Yes, CityGrip Recovery covers the A12 for mobile tyre fitting, 24 hours a day. We are based at 68 Ruckholt Road in Leyton E10, on the A106 at the Lea Interchange where it meets the A12, so this road runs past our door. Call 07960 200253 for punctures, blowouts, wheel changes, run-flats and TPMS work from Poplar and Bow out through Leytonstone, Redbridge, Gants Hill, Romford, Brentwood, Chelmsford, Witham, Kelvedon and Colchester to Copdock Mill. Roadside fitting on the urban and ordinary sections starts from £140. Where the vehicle sits on fast dual carriageway and the job needs live-traffic safety procedure, motorway rates of £250 to £750 apply. The price is agreed on the phone first, and there is no call-out fee.
The A12 changes character at the M25, and so does the tyre job
The A12 is really two roads sharing one number, and a roadside tyre fit on each is a different piece of work. From its start just north of the Blackwall Tunnel, at the junction with the A102 and the A13 in Poplar, out to Brook Street Interchange at the M25 is roughly fourteen miles of Transport for London Road Network. That means red route the whole way, no stopping at any time, and the whole London length sits inside the London-wide Ultra Low Emission Zone, where a non-compliant vehicle pays £12.50 for the day. Past Brook Street, which is A12 junction 11 and M25 junction 28 at the same time, the road becomes an all-purpose trunk dual carriageway running 52 miles across Essex to Copdock Mill near Ipswich: mostly grade separated, national 70mph on the open sections, and a mix of dual two and dual three lanes with eight changes in width between the M25 and Ipswich.
That split decides the price. On Eastern Avenue at Gants Hill, in a retail park at Gallows Corner, on a slip road off the Green Man or on the forecourt at Boreham services, this is ordinary work and roadside fitting starts from £140. Where the vehicle is stuck on open dual carriageway past Ingatestone, Boreham or Kelvedon, with traffic running at 70mph and the job needing live-traffic safety procedure before anyone can touch a wheel nut, motorway rates of £250 to £750 apply. You are told which of the two you are looking at on the phone, before anyone leaves the yard, and there is no call-out fee added afterwards.
Blackwall to Brook Street: viaducts, tunnels and no verge to work on
From Poplar to Hackney Wick you are on the East Cross Route, built from around 1970 to a lower standard than the rest of the Ringway 1 scheme it belonged to: two or three lanes each way, and a hard shoulder only where there happened to be spare ground. South of Old Ford there are tight bends and forward visibility as low as 50 metres in places, which is why the limit was cut from 50 to 40mph after a 2002 safety report. Bow Interchange is a triple-level junction over the River Lea, opened in 1967 with a 1,450ft viaduct, where the A11 Bow Road and the A118 Stratford High Street come in. One blocked lane there backs up three trunk routes at once, which is exactly why a car stopped on the flyover with a shredded tyre is not somewhere a fitter should be kneeling.
North of the Lea Interchange, where our own yard sits on the A106 Ruckholt Road, the 1990s M11 link road runs in deep cuttings and through the 175 metre twin-bore George Green cut-and-cover tunnel at Wanstead, then under the Green Man roundabout in an underpass opened in 1999. Neither has a refuge. From Redbridge Roundabout, where the North Circular crosses the A12 on a viaduct and which the RAC lists as an accident hotspot as well as a congestion point, the road becomes Eastern Avenue: a 1920s and 1930s arterial about ten miles long, with traffic lights at almost every junction, a roundabout at Gants Hill that has the tube station directly underneath it, the signalised Moby Dick crossroads at Chadwell Heath (named after the pub, which took its name in turn from whale jaw bones used to mark an old tollgate), and houses and shops fronting straight onto the carriageway. Limits are 40 and 50mph, including a statutory 2,800 metre 40mph length across Havering. At Newbury Park the road runs tight against the Grade II listed 1949 bus station canopy, an Oliver Hill design that won a Festival of Britain award in 1951, because the original station building was demolished in 1956 to widen Eastern Avenue. There is often no verge at all to work in.
Gallows Corner, where the A127 Southend Arterial Road and the A118 meet the A12 at Romford, is the pinch point at the London end. Approach limits are 50mph on the A12 and 40mph on the A127, with 30mph at the junction itself, and the 50-year-old temporary flyover is being fully replaced: the junction closed to general traffic from 9pm on 23 June 2025 and only partially reopened on 10 May 2026, with full reopening still to be confirmed. The compensation is space. Gallows Corner Retail Park, the Tesco Extra beside it and the B&Q almost opposite give proper off-road ground to jack a car up on, which is more than most of this road offers.
Essex: junction 11 to junction 33, and the two lanes that never became three
A12 junction numbers run from 11 at Brook Street Interchange, which is also M25 junction 28, to 33 at Copdock Mill near Ipswich, which doubles as junction 55 of the A14. Numbers 1 to 10 were reserved for use inside the M25 and never used, and the numbers only appeared on the road in December 2003, which is why plenty of drivers still give directions here by place name rather than junction. Brook Street has had a £170m National Highways upgrade adding a dedicated two-lane loop from the M25 anticlockwise onto the A12 eastbound, plus new slip roads and four new bridges; up to 7,500 vehicles pass through the roundabout at peak times. From the Brentwood bypass, which opened in November 1965, the road runs three lanes each way to Chelmsford apart from about a mile of the Ingatestone bypass that stays at two, and the northbound three-lane stretch out of Brentwood was actually cut back to two to manage the queue at the narrowing. That is a hard-braking point, and hard braking in a queue is where kerbing and sidewall damage happen.
From Boreham Interchange at junction 19, the end of the 1986 Chelmsford bypass, through to Marks Tey at junction 25, the road drops to dual two lanes and carries up to 90,000 vehicles a day. HGVs make up 9 to 12 percent of that traffic because of Felixstowe and Harwich, roughly double the share on a normal A-road. The widening that was meant to fix it, junctions 19 to 25 at three lanes each way, was cancelled by the Secretary of State for Transport on 8 July 2025, so the layout stays as it is. National Highways says it will pursue smaller junction, signage and speed management improvements under the 2026 to 2031 programme instead, and the A120 Braintree to A12 scheme has been dropped from that programme as well, which keeps the freight exactly where it is. Junctions through Hatfield Peverel, Witham and Kelvedon are closely spaced with short slip roads, which is the stated reason National Highways funded £840,000 of average speed cameras around Kelvedon, alongside a second £740,000 scheme at Hughes Corner on the Essex and Suffolk border near Dedham and East Bergholt.
Speed is why we treat these sections as motorway-grade work rather than ordinary roadside work. In one hour of checks between Chelmsford and Witham in June 2025, Essex Police recorded more than 180 speeding offences, with three drivers detected above 100mph and top speeds of 140mph, 121mph and 110mph. Even inside roadworks the pattern holds: average speed cameras on a temporary 40mph limit logged 916 offences in nine weeks, almost fifteen a day. Add the current resurfacing between junctions 20b and 22 and between junctions 24 and 25, which runs to October 2026 with weeknight closures from 9pm to 5am, and the nearside of that stretch is a poor place to be standing while a bead is broken and a tyre is machined off.
Where we will fit at the roadside on the A12, and where we will not
We will not set up in a running lane. That rules out the East Cross Route viaducts, Bow Flyover, the Eastway tunnel on the northbound slip at Hackney Wick, the George Green Tunnel at Wanstead and the Blackwall Tunnel itself, which is 30mph with a 4.0m height limit northbound and 4.7m southbound. In London the red route also makes stopping unlawful as well as unsafe, so a wheel change on the hard red line in Poplar, Leyton, Ilford or Romford risks a penalty charge on top of the risk from traffic. If you are stuck somewhere like that, the honest answer is recovery to a safe place first and the tyre fitted there. Say so on the phone and we will price the job that actually needs doing rather than the one that sounds cheaper.
There is no continuous hard shoulder on the A12: it is an all-purpose trunk road, not a motorway, and on the London section there is a hard shoulder only where there happened to be spare space when it was built. In practice the usable working spaces are lay-bys, slip roads, junction roundabout land set back from live lanes, the forecourt at Boreham services on junction 19 (still called Chelmsford services by most people locally) and the service area at junction 28 Cuckoo Farm, which opened with that dumbbell junction in December 2010 beside Colchester Community Stadium. Retail park car parks are the other realistic option and there are good ones right on the road: Gallows Corner Retail Park with the Tesco Extra and B&Q around it, and Tollgate Centre and Stane Retail Park immediately at junction 26 Stanway. If your tyre is losing air slowly rather than gone completely, nursing it to one of those at low speed and meeting us there is usually safer and cheaper than stopping on the carriageway.
Where a vehicle genuinely cannot be moved and sits on the nearside of a 70mph section, we will still come out, but that is live-traffic work at £250 to £750 rather than the £140 urban rate, because it needs proper protection in place for the whole time the wheel is off. And where there is sidewall damage plus wheel or suspension damage, or no usable spare and no safe space to work, we will tell you straight that recovery is the right call rather than sell you a roadside fit that should not be attempted there.
How to describe where you are on this road so we reach you first time
The A12 catches people out because half of it has no junction numbers at all. In London, quote landmarks instead: Blackwall Tunnel northern approach, Bow Flyover, Hackney Wick, Lea Interchange, Green Man, Redbridge Roundabout, Gants Hill, Newbury Park, Moby Dick at Chadwell Heath, Gallows Corner. In Essex, give the junction number and the interchange name where you know it: junction 11 Brook Street, junction 15 Webbs Farm, junction 19 Boreham, junction 25 Marks Tey, junction 26 Stanway, junction 27 Spring Lane, junction 28 Cuckoo Farm, junction 29 Crown Interchange at Ardleigh and junction 33 Copdock Mill.
Direction matters more here than on most roads, because exits are far apart and the carriageways are separated by a central reservation you cannot cross. Tell us whether you are heading toward Colchester and Ipswich or back toward London, and give the last junction, roundabout or set of lights you passed. If there is a marker post or a driver location sign within sight, read it out. The Essex sections also carry variable message signs, CCTV and incident detection equipment installed under a technology package announced by government in 2008, so the sign you passed can be a useful reference point in itself. A what3words pin works well in the dark between Witham and Kelvedon where there is little to describe, and if you are anywhere near Gallows Corner tell us which approach you came in on and which diversion you followed, because the works there have moved traffic onto unfamiliar side roads. If you are reporting debris or a spill rather than calling us out, the A12 is a trunk road maintained by National Highways on 0300 123 5000, not by the county or borough.
What we bring to an A12 job, and the technical side of the fit
We fit cars, vans and 4x4s. That matters on this corridor because of the sheer volume of light commercials running to the Essex ports and the trade and retail parks off junctions 25, 26 and 28: van tyres are usually reinforced or C-rated and carry different load and pressure ratings from the car version of the same size, and fitting the wrong one is a genuine safety issue on a fully loaded vehicle at 70mph past Kelvedon. Tell us the size off the sidewall (for example 225/45 R17 94W), the load index and speed rating, and whether the vehicle carries a full-size spare, a space saver or only a sealant kit. Plenty of newer cars come with the sealant kit and nothing else, which is the whole reason roadside fitting exists on a road with nowhere to stop.
Run-flats are common on the German saloons and estates that fill this road, and they need proper machine work rather than hand levers, both on and off. We handle direct TPMS sensors carefully during the change and reset or relearn the system afterwards where the vehicle requires it, so the dashboard warning goes out instead of staying on for the rest of the journey. Locking wheel nuts are worth sorting before we arrive: the key is normally in the glovebox, under the boot floor or with the spare wheel, and if it is lost or the nut has been rounded off by an air gun, say so on the call so the right removal kit comes out with us. The legal minimum tread in the UK is 1.6mm across the central three quarters of the tread and around the whole circumference, and if the other tyre on that axle is close to it, we will say so rather than leave you to find out at an MOT.
Why choose CityGrip on the A12
We are a working recovery and tyre outfit based at 68 Ruckholt Road, Leyton E10 5NP, on the A106 where it joins the A12 at the Lea Interchange, so the London end of this road is home ground and the Essex end is a straight run out. The pricing is deliberately plain: from £140 for roadside fitting on the ordinary and urban sections, £250 to £750 where the job sits on fast dual carriageway and needs live-traffic safety procedure, agreed on the phone before anyone sets off, with no call-out fee bolted on afterwards. We keep the fee side low and transparent because a puncture on Eastern Avenue should not turn into an argument about the bill at the kerbside, and we would rather tell you a job needs recovery than sell you a roadside fit that is not safe to do at a live 70mph nearside. If your tyre went because of debris, a pothole or another driver, our sister claims service at citygripclaims.co.uk deals with the paperwork side separately.
What actually causes tyre failure here
Debris is the problem this road is known for. Over four nights in March 2026 Colchester City Council cleaned the A12 between junctions 26 and 29 in both directions: seven officers removed 3.7 tonnes of waste by hand, including 19 tyres and 13 abandoned road signs, and a mechanical sweeper took roughly ten tonnes more, close to 14 tonnes in total. The council said plainly that clearing it reduces the risk of accidents and prevents damage to vehicles. Blown lorry tyre carcasses are a constant on the Boreham to Marks Tey stretch where HGVs are 9 to 12 percent of traffic, and a carcass strike at 70mph takes out a sidewall rather than giving you a slow puncture you can drive on. Surface condition adds to it: the A12 was rated the worst A-road in England by Transport Focus, with 64 percent overall satisfaction and only 52 percent of drivers satisfied with the road surface in a survey of more than 9,500 drivers; the concrete carriageway between Marks Tey and Stanway had to be dug out and rebuilt in asphalt; and the resurfacing between junctions 20b and 22 and between junctions 24 and 25, running to October 2026, brings temporary surfaces, joints, steel plates and narrowed lanes. In London the damage pattern is different and mostly kerbing: Redbridge Roundabout, Gants Hill, the Green Man, Moby Dick and Gallows Corner all have tight multi-lane entries, deep kerbs and heavy lane changing, and a bad clip there splits a sidewall or buckles a rim. Diesel and oil spills finish the list. They close sections of this road regularly, with documented examples between junctions 21 and 22 near Hatfield Peverel, between junctions 18 and 19 at Chelmsford and between junctions 25 and 26 at Marks Tey, and a contaminated surface removes grip exactly where people are braking hardest.
How we decide whether a tyre on the A12 can be repaired, and when it cannot
Not every flat tyre on the A12 can be repaired. We assess the damage against BS AU 159, the British Standard for repairs to tyres for motor vehicles used on the public highway, and we assess tread against Regulation 27 of the Road Vehicles (Construction and Use) Regulations 1986. If the tyre falls outside those limits we will tell you it needs replacing rather than patch it and hand it back. Mobile tyre fitting on ordinary roads starts from £140. On a motorway or hard shoulder it is £250 to £750, because the work is done alongside live traffic and takes more time, more equipment and more care.
The repairable area is measured, not guessed
BS AU 159 sets a repairable band across the tread as a percentage of the tyre’s nominal section width: 60% up to and including 155mm, 65% over 155mm up to 200mm, and 70% over 200mm. On a 205 section tyre that is a 144mm band; on a 225 it is 158mm. Damage outside that band is not repairable. It is not the same thing as the “central three quarters” wording in the tread depth law, which is the mix-up most tyre pages make.
Maximum injury size, and why the tyre comes off the wheel
Measured at the base of the injury after preparation, the maximum diameter of penetration damage is 6mm. The standard requires the tyre to be removed from the wheel and inspected inside and out before any repair, because the damage that decides the answer is often only visible from the inside. A plug pushed into a tyre that is still on the rim is not a repair the standard recognises.
What the standard does not accept
Liquid sealants, externally applied plugs, an inner tube fitted into a tubeless tyre and temporary repairs all sit outside BS AU 159. Sidewall damage beyond cosmetic scuffing is not approved for repair at all. There is no limit on the number of minor repairs inside the repairable band provided the patches do not overlap, and a tyre repaired correctly keeps its original speed and load capabilities.
Tread depth and the law
Regulation 27 requires at least 1.6mm of tread depth throughout a continuous band covering the central three quarters of the breadth of tread, right round the tyre. A cut over 25mm, or 10% of the section width if that is greater, deep enough to reach the ply or cord makes the tyre illegal, as does any lump, bulge or tear caused by separation, or any exposed cord. In the MOT, tread below the requirement is recorded as a Dangerous defect. TyreSafe puts the penalty at up to £2,500 and three penalty points, per tyre.
TPMS, explained properly
Direct TPMS uses a battery powered sensor inside each wheel, each with its own ID that has to be registered to the car so it knows which sensor is where. Indirect TPMS has no sensors and infers a soft tyre from wheel speed through the ABS, so it needs resetting and a period of driving to relearn after a tyre change. Sensor batteries are sealed in, typically last five to ten years and cannot be replaced separately, so a sensor that dies during a wheel change means a new sensor. On an M1 car first used on or after 1 January 2012, a TPMS malfunction is a Major MOT defect, so we tell you at the roadside rather than let you find out at the test.
Run-flats and locking wheel nuts
Bridgestone rates its run-flat technology for up to 50 miles at up to 50mph after a loss of pressure, and run-flats need TPMS to work, because you cannot feel the deflation. Once a run-flat has been driven on while flat it is replaced, not repaired, because the internal damage cannot be seen. For a lost locking wheel nut key we try a master key set first, which takes the nut off undamaged. If the nut is rounded or the pattern is unknown, a reverse threaded extractor socket grips and removes it, but the nut is destroyed doing so and needs replacing.
When we will not fit or repair at the roadside on the A12
- Any position on a live carriageway where working alongside traffic is not safe. We recover the vehicle to somewhere safe and fit it there instead.
- Damage outside the repairable band, or a penetration larger than 6mm measured at the base after preparation.
- Sidewall damage beyond cosmetic scuffing, and any tyre with exposed cords, a lump, bulge or tear from separation, or belt separation.
- Any tyre that has been driven on while flat, run-flats included, because of the secondary damage that cannot be inspected away.
- Tread already below 1.6mm across the legal band, a broken bead core, liner deterioration, solvent contamination, or an earlier repair that falls outside the standard.
- A replacement whose load index or speed rating is below the vehicle manufacturer’s specification. Fitting one is a Major MOT defect, and a load rating insufficient for the axle weight is a Dangerous one, so we source the correct tyre rather than fit what is nearest.
Wheel nuts and bolts go back to the vehicle manufacturer’s torque figure with a calibrated torque wrench, in a star pattern, in stages. Judging by feel or finishing with an impact gun risks stretched or snapped studs, distorted brake discs and cracked alloys. The familiar re-torque intervals, 30 minutes stationary or 40 to 80km of driving, come from commercial vehicle guidance rather than car law, but we will re-check on request.
If a tyre cannot be repaired and we do not carry the right size for your vehicle, we say so on the phone before setting off rather than after arriving. Where a roadside fit is not the safe answer, recovery is: we are a vehicle recovery firm first, so the car can be moved rather than left where it is.
If you stop on the the A12 itself, follow the National Highways procedure before anything else: get as far left as you can, use the hard shoulder or an emergency area, leave the car by the nearside doors, and get behind the barrier and up the bank. Do not attempt a wheel change on the hard shoulder. If you are stopped in a live lane and cannot get out safely, stay belted in with your hazard lights on and call 999. This procedure is why motorway work is priced at £250 to £750 rather than £140, and why some motorway jobs end in recovery to a safe place rather than a roadside fit.

A12 mobile tyre fitting FAQs
My tyre has gone inside the Blackwall Tunnel or on the northern approach. What should I do?
Do not attempt anything yourself. The tunnel is 30mph with a height limit of 4.0m northbound and 4.7m southbound, and TfL has recorded 1,604 closures in a nine month period, 287 of them caused by breakdowns. Follow the instructions from tunnel staff and the control room and let them get you clear of the bore. Once you are somewhere safe on the Poplar side, call 07960 200253 and we will fit the tyre there. Bear in mind that both Blackwall and Silvertown have been charged crossings since 7 April 2025, so any movement through the tunnel is a paid one.
I am on the elevated East Cross Route near Hackney Wick with a flat. Can you come to me there?
Not to fit in a live lane. That stretch was built from around 1970 with only two or three lanes each way, a hard shoulder only where there happened to be spare space, no intermediate exits and no refuge. If the tyre still holds any air, drive slowly to the next exit and stop somewhere off the carriageway, then call us to that spot. If it does not hold air at all, the correct answer is recovery to a safe place first and the tyre fitted there, and we will tell you that on the phone rather than send a fitter onto the viaduct.
Do you still work around Gallows Corner while the flyover replacement is going on?
Yes. The junction closed to general traffic from 9pm on 23 June 2025 so the 50-year-old temporary flyover could be replaced, and it partially reopened on 10 May 2026 with full reopening still to be confirmed, so tell us which approach you came in on and which diversion you followed. The retail park, the Tesco Extra beside it and the B&Q almost opposite give proper off-road space to work in, so if you can reach one of those car parks it is a straightforward job at the £140 rate.
Is it safe to change my own wheel on Eastern Avenue at Gants Hill or Newbury Park?
We would not. Eastern Avenue is a 1920s and 1930s arterial with traffic lights at almost every junction, roundabouts and buildings fronting straight onto the road, so there is often no verge or footway width at all. At Gants Hill the tube station sits directly underneath the roundabout and the pedestrian subways feed into it. In a side street or car park with a level surface and a proper jacking point, changing it yourself is reasonable. On the carriageway itself, with a 40 or 50mph limit and no verge, it is not.
Will I get a ticket for stopping on the A12 in Ilford or Romford?
Very possibly, and there is a second cost behind it. The whole London length of the A12 is on the Transport for London Road Network as a red route, and red lines mean no stopping, parking, loading or unloading at any time. Redbridge and Havering also enforce moving traffic contraventions such as box junctions and banned turns by CCTV. On top of that, every London mile of the A12 sits inside the Ultra Low Emission Zone, so a non-compliant vehicle picks up a £12.50 charge for the day it broke down there. That is why we normally work off the red route rather than on it.
What does mobile tyre fitting cost on the A12?
Roadside fitting on the ordinary and urban sections, which covers most of the London length and any job done in a lay-by, slip road, forecourt or car park, starts from £140. Where the vehicle is stuck on fast dual carriageway in Essex and the work needs live-traffic safety procedure, motorway rates of £250 to £750 apply. Which of the two applies is settled on the phone on 07960 200253 before anyone sets off, and there is no call-out fee added on top.
Do you cover the A12 past Chelmsford, out through Witham, Kelvedon and Marks Tey?
Yes, the whole Essex length from junction 11 Brook Street Interchange at the M25 through to junction 33 Copdock Mill near Ipswich. Be aware that the run from junction 19 Boreham to junction 25 Marks Tey is only dual two lanes carrying up to 90,000 vehicles a day, with heavy goods vehicles at 9 to 12 percent of traffic, so we will talk through the best meeting point with you rather than assume the nearside is workable where you are.
Can you meet me at Boreham services on junction 19?
Yes, and it is a sensible place to head for if the tyre will get you that far. Boreham services, still called Chelmsford services locally, is a BP forecourt with M&S Food, a Wild Bean Cafe, a McDonald's Drive Thru, a Premier Inn, showers and toilets, and it can be reached from the A131, A138 and B1137 as well as the A12. Beaulieu Park station opened next to it on 26 October 2025 with more than 700 parking spaces, so there is more level, lit ground there than at almost any other junction on this road.
What about the Colchester end? Where is sensible to meet there?
Junction 26 Stanway is the practical one: Tollgate Centre shopping park has more than 489 free spaces about four miles west of the city centre, and Stane Retail Park sits immediately at the junction. Further north, junction 28 Cuckoo Farm is a dumbbell layout with a roundabout each side of the A12 linked by a bridge, opened in December 2010 to serve Colchester Community Stadium, and there is a service area there. All of those give a level, lit surface well away from live lanes.
The A12 is closed overnight for resurfacing near Witham. Can you still reach me?
Yes, though it may take longer to get to you. National Highways is resurfacing between junctions 20b and 22 and between junctions 24 and 25 through to October 2026, with weeknight closures from 9pm to 5am and traffic diverted onto local roads. Tell us which diversion signs you followed and roughly where you left the main road, because on those nights a postcode on its own is not enough to find a stopped vehicle.
The tyre picked up a bolt on the A12 near Marks Tey. Can it be repaired or does it need replacing?
A repair is only permitted within the central three quarters of the tread, in line with the British Standard for tyre repairs. Anything in the shoulder or sidewall, a cut longer than the permitted limit, a tyre that has been run flat and damaged its inner liner, or one already below the legal 1.6mm, has to be replaced. On this road most failures come from debris strikes and kerbing rather than a clean nail in the tread, and those are replacements. We will tell you which you have when we look at it.
I have run-flats on my car. Can they be fitted at the roadside on the A12?
Yes. Run-flats need proper machine work rather than hand levers, and they are not generally repairable once they have been driven on in a deflated state. If yours has carried you from the Green Man to a car park at Gallows Corner while flat, expect to replace rather than repair it. Give us the full size, load index and speed rating off the sidewall when you call, so the right tyre comes out with us on the first visit rather than the second.
Will the tyre pressure warning light stay on after you change the wheel?
It should not. Where the car has direct TPMS sensors inside the wheel, we handle them carefully during the change and then reset or carry out the relearn procedure so the dashboard warning clears before we leave. Where the sensor has already been destroyed by the same kerb strike that killed the tyre, which happens often enough at Redbridge Roundabout and Gants Hill, we will tell you at the roadside rather than leave you guessing why the light is still on.
I have locking wheel nuts and cannot find the key. Can you still do the job?
Usually, but tell us on the call. The key is normally in the glovebox, under the boot floor or stored with the spare wheel, and finding it before we arrive saves time you would otherwise spend sitting beside a busy road. If it is genuinely lost or the nut has been rounded off by an air gun, we bring removal equipment, but that adds time to the job, and on somewhere like Eastern Avenue or a junction 25 slip road that extra time is time you are exposed to traffic.
I have a space saver on. Can I drive from Brentwood to Colchester on it?
No. Space savers are normally limited to 50mph and to short distances, which does not sit well with a 70mph dual carriageway carrying Felixstowe and Harwich freight. Get to the nearest safe stop instead: a lay-by, a junction, Boreham services at junction 19 or the retail parks at junction 26 Stanway, and have the proper tyre fitted there. Call 07960 200253 and tell us where you are heading, and we will meet you at the sensible point rather than at the far end of Essex.
