Our attendance guarantee
Once we have confirmed your job with you and agreed the price, we guarantee to attend. We cannot give an arrival time, because it depends on where you are and, where the police or National Highways are managing the scene, on when they allow access. The price is agreed before we set off, with no separate call-out fee. The guarantee does not extend to the Dartford Crossing itself or its approach roads, where only a constable or traffic officer may move a vehicle.

The M25 is a dangerous place to be stuck with a flat tyre: heavy traffic, high speeds and, on the all lane running sections, no hard shoulder to stop on. Once you are safe, tell us your junction and direction of travel and we will agree the price and the plan with you before we set off.
More about the M25 for mobile tyre fitting
The M25 is about 117 miles (188 km) long and runs round most of Greater London. The Dartford Crossing, between J31 and J1a, closes the ring in the east. It is the A282, not motorway, and J1a and J1b are on it. Junction numbers rise clockwise from J1a on the Kent side to J31 on the Essex side. The main interchanges are the M20 at J3, the M26 at J5, the M23 at J7, the A3 at J10, the M3 at J12, the M4 at J15, the M40 at J16, the M1 at J21, the A1(M) at J23, the M11 at J27 and the A13 at J30.
The M25 has four motorway service areas: Clacket Lane between J5 and J6, Cobham between J9 and J10, South Mimms off J23 and Thurrock, reached by leaving the M25 at J30 or J31. There is no service area between Cobham and South Mimms, or between South Mimms and Thurrock. Head for one only if you can reach it safely; otherwise follow the steps in the next section.
The Dartford Crossing has its own rules. Under the Dartford-Thurrock Crossing Regulations 1998 (regulation 9), only a constable or traffic officer may move a vehicle that is at rest because of a breakdown on the crossing, other than in a designated parking area, or on its approach roads, and nobody else may repair it without their express permission. Our attendance guarantee does not extend to the crossing itself or its approach roads, where only a constable or traffic officer may move a vehicle. Elsewhere on the M25, call 07960 200253 once you are safe: the price is agreed before we set off.
Smart motorway and hard shoulder sections on the M25
Not all of the M25 has lost its hard shoulder. National Highways' smart motorway map (January 2025 edition) lists two all lane running sections, J5 to J7 and J23 to J27, where the hard shoulder has become a running lane and emergency areas stand in for it. A map footnote makes J6 to J7 eastbound a four-lane controlled motorway, so part of that stretch keeps a hard shoulder, but do not count on one between J5 and J7: read the signs. The map shows controlled motorway, a smart motorway type that keeps a permanent hard shoulder, on J2 to J3, J7 to J23 and J27 to J30. A hard shoulder is for emergencies only.
If a tyre fails or a warning light comes on, follow these steps from National Highways and Highway Code rule 277. Step 1: do not stop in a live lane unless it is absolutely necessary, and leave the motorway at the next exit or pull into a service area if possible. Step 2: if you cannot do that, go left. Move into the left lane, pull into an emergency area or onto a hard shoulder if you can, and stop as far to the left as possible, leaving space to exit, with your wheels turned to the left. If you can, stop just beyond an emergency telephone. A hard shoulder gives less protection than other places of relative safety because it is so close to fast traffic. Step 3: switch your hazard lights on, and your sidelights too if it is dark or visibility is poor. Step 4: if it is safe and possible, exit by the side furthest from the traffic and make sure passengers do the same. Wear high-visibility clothing if it is within easy reach, keep passengers away from the carriageway, children under control and animals in the vehicle or, in an emergency, under control on the verge. Step 5: wait well away from the vehicle and moving traffic, behind the safety barrier where there is one, aware of unseen hazards such as sudden drops, uneven ground or debris. Do not stand where your vehicle could be forced into you, do not return to it even if it is raining, cold or dark, do not attempt repairs and do not put a warning triangle on the carriageway. Step 6: if you cannot reach a place of relative safety and also cannot leave the vehicle safely, stay in it with your seat belt and hazard lights on, call 999 immediately and ask for the police, or press the SOS button if your vehicle has one and ask for the police.
If you cannot leave the vehicle, or you have not stopped near a free emergency telephone, call 999 immediately and ask for the police. Otherwise use the free emergency telephone, or call National Highways on 0300 123 5000, facing the traffic while you speak and saying if you are vulnerable. Emergency areas are marked by a blue sign with an orange SOS telephone symbol and may have orange surfacing, and their phones link directly to National Highways control rooms. If you are in an emergency area, you must use the emergency telephone and follow the operator's advice for exiting; a lane may need to be closed so you can rejoin safely. Then call us on 07960 200253.
Why choose CityGrip on the M25
CityGrip Recovery is a car recovery company. We are open 24 hours a day on 07960 200253 by phone or WhatsApp, and we work on cars, vans and 4x4s. On the M25 we can supply and fit a replacement tyre, deal with locking wheel nuts and seized wheels, or arrange recovery. If you are in a live lane, get to safety first by following the steps in the smart motorway section above, and call us once you are safe.
The price is agreed before we set off, with no separate call-out fee. Motorway mobile tyre fitting runs from £250 to £750 and ordinary-road mobile tyre fitting from £140. National Highways says recovery operators are never expected to work in a live lane, and that it allocates traffic officers or calls on the police so they never have to. We guarantee attendance on every job we confirm (not on the Dartford Crossing itself or its approach roads), and where the police or National Highways are managing the scene we attend as soon as they allow access. If a tyre cannot be fitted safely, we arrange recovery.

How we decide whether a tyre on the M25 can be repaired, and when it cannot
Not every flat tyre on the M25 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 motorway work takes more planning and time and can only start once the scene is safe.
What should I do first if my tyre fails on the M25, before I call for mobile tyre fitting?
Get to safety first. Do not stop in a live lane unless absolutely necessary. Leave at the next exit or service area if you can; otherwise go left and stop as far left as possible with your hazard lights on (full steps above, from Highway Code rule 277). If you cannot reach a place of relative safety and also cannot leave the vehicle safely, stay in it with your seat belt and hazard lights on and call 999 immediately, asking for the police. Call us once you are safe.
What should I do if my tyre fails on the Dartford Crossing?
The crossing is the A282, not a motorway. Only a constable or traffic officer may move a vehicle at rest because of a breakdown there (other than in a designated parking area), and repairs need their express permission. Highway Code rule 275 applies on any road: stop in a place of relative safety if you can and keep well away from your vehicle and moving traffic. If you are in danger, call 999. Our attendance guarantee does not extend to the crossing or its approach roads.
What is an emergency area on the M25 and when should I use it?
An emergency area is a bay marked by a blue sign with an orange SOS telephone symbol, with a phone linked to control rooms. Use one in an emergency if you cannot leave the motorway or reach a service area. On the M25 they stand in for the hard shoulder on J5 to J7 and J23 to J27, though part of J6 to J7 keeps one. You must use the emergency telephone and follow the operator's advice for exiting; a lane may need closing so you can rejoin safely.
What does guaranteed attendance mean?
Once we have confirmed your job with you and agreed the price, we guarantee to attend. We cannot give an arrival time, because it depends on where you are and, where the police or National Highways are managing the scene, on when they allow access. If you are in a live lane, follow Highway Code rule 277 and the steps in the smart motorway section first, and call 999 if you cannot reach a place of relative safety and also cannot get out safely. Do not wait for us in a live lane: call us once you are safe, and we attend as soon as the police or National Highways allow access. Our guarantee does not extend to the Dartford Crossing itself or its approach roads, where only a constable or traffic officer may move a vehicle.
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.
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 a 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, a master key set can sometimes take 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 M25
- Any position the police or National Highways have not yet made safe. We attend as soon as they allow access, and if the tyre cannot be fitted safely at the roadside we arrange recovery.
- 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 should go back to the vehicle manufacturer’s torque figure, tightened 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.
If a tyre cannot be repaired and we cannot supply 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, we arrange recovery: we are a vehicle recovery firm first, so the car can be moved rather than left where it is.
If you stop on the M25 itself, follow Highway Code and National Highways guidance before anything else. Leave the motorway at the next exit or pull into a service area if you can. If you cannot, stop as far left as you can with your wheels turned to the left and your hazard lights on. If it is safe and possible, exit by the side furthest from traffic and wait well away from the vehicle and moving traffic, behind the safety barrier where there is one, watching for unseen hazards such as drops or uneven ground. Use the emergency telephone, or call 999 and ask for the police if you have not stopped near one. Do not attempt a wheel change and do not return to the vehicle. If you cannot reach a place of relative safety and also cannot get out safely, stay in the vehicle with your seat belt and hazard lights on and call 999 and ask for the police. Motorway work is priced at £250 to £750, against ordinary-road fitting from £140, because it takes more planning and time, and some motorway jobs end in recovery to a safe place rather than a roadside fit.

M25 mobile tyre FAQs
Do you cover the whole M25 including the Dartford Crossing?
We cover every junction of the M25 and take calls 24 hours a day, but our attendance guarantee does not extend to the Dartford Crossing or its approach roads. The crossing is the A282, not motorway, and J1a and J1b are on it. Under the Dartford-Thurrock Crossing Regulations 1998, only a constable or traffic officer may move a vehicle at rest because of a breakdown there, other than in a designated parking area, and repairs need their express permission. Elsewhere on the M25, call 07960 200253 once you are safe.
What if I get a flat on a smart-motorway section of the M25?
National Highways lists two all lane running sections on the M25, J5 to J7 and J23 to J27, where emergency areas stand in for the hard shoulder. Part of J6 to J7 keeps a hard shoulder, but do not count on one between J5 and J7. Get to safety first and follow the breakdown steps in the smart motorway section above. We guarantee attendance on every job we confirm (not on the Dartford Crossing itself or its approach roads), and where the police or National Highways are managing the scene we attend as soon as they allow access.
Can you reach me on the M25 around Heathrow?
We take calls 24 hours a day. We cover every junction of the M25. Our attendance guarantee does not extend to the Dartford Crossing itself or its approach roads. We guarantee attendance on every job we confirm (not on the Dartford Crossing itself or its approach roads), and where the police or National Highways are managing the scene we attend as soon as they allow access. If a tyre cannot be fitted safely, we arrange recovery. Once you are safe, call 07960 200253 and give us your direction and the last junction you passed.
How much is a mobile tyre change on the M25?
Motorway mobile tyre fitting on the M25 runs from £250 to £750, and ordinary-road mobile tyre fitting starts from £140. The price is agreed before we set off, with no separate call-out fee. We attend as soon as the police or National Highways allow access.
Can you fit a tyre if I have no spare on the M25?
Yes. Once the scene is safe we can supply and fit a replacement tyre on the M25, or arrange recovery if it cannot be fitted safely at the roadside. The exception is the Dartford Crossing and its approach roads (the A282), where only a constable or traffic officer may move a vehicle at rest because of a breakdown (other than in a designated parking area) and repairs need their express permission, so our attendance guarantee does not extend there.
Should I change the tyre myself on the M25?
No. Highway Code rule 277 says not to attempt repairs on a motorway and not to put a warning triangle on the carriageway. On the Dartford Crossing and its approach roads (the A282, not a motorway) only a constable or traffic officer may move a vehicle at rest because of a breakdown (other than in a designated parking area), and repairs need their express permission. If you are in danger, call 999, and call us once you are safe.
How do I tell you exactly where I am on the M25?
Once you are safe, tell us your direction (clockwise or anticlockwise), the last junction you passed (for example J21 for the M1) and any numbers and letters on a marker post or driver location sign. Do not walk along the carriageway, hard shoulder or verge to find one: read a marker post only if you can see it from where you are safe. A mobile mapping app can also tell you your position.
Can you change tyres on vans and 4x4s on the M25?
Yes. We work on cars, vans and 4x4s, and we deal with locking wheel nuts and seized wheels. The price is agreed before we set off. We guarantee attendance on every job we confirm (not on the Dartford Crossing itself or its approach roads), and where the police or National Highways are managing the scene we attend as soon as they allow access. If a tyre cannot be fitted safely at the roadside, we arrange recovery.
My car has run-flat tyres, do I still need you on the M25?
A run-flat can be driven a limited distance at reduced speed after losing pressure, but how far depends on the tyre model, so do not rely on it. It is a way to leave the motorway, not a repair, and a run-flat that has been driven on while flat is replaced, not repaired. Leave the motorway at the next exit or pull into a service area if you safely can; if you cannot, follow the steps in the smart motorway section above. Once you are somewhere safe, call us to supply and fit a replacement tyre or arrange recovery.
My tyre pressure warning light has come on near J5 Clacket Lane, can I carry on?
Treat it as a warning that something is wrong. Clacket Lane services sit between J5 and J6, in the all lane running section. National Highways says that with a red or amber warning light you should leave at the next exit or pull into a service area if possible, and not stop in a live lane unless absolutely necessary. If the tyre is going down or the car handles abnormally and you cannot reach the next exit or service area safely, follow the steps in the smart motorway section above.
What is the legal tyre tread depth for driving the M25?
The legal minimum for cars, light vans and light trailers is 1.6 mm across the central three-quarters of the tread and around the whole circumference (Highway Code Annex 6). National Highways advises checking tyre pressure, tread depth and tyre age, including the spare, before a long journey, so do it before you set off rather than at the roadside. If your tyre is close to or below the limit, we offer mobile tyre fitting and can supply and fit a replacement.
What's the nearest service station on the M25 if I break down?
The M25 has four service areas: Clacket Lane between J5 and J6, Cobham between J9 and J10, South Mimms off J23 and Thurrock, reached by leaving the M25 at J30 or J31. There is none between Cobham and South Mimms, or between South Mimms and Thurrock. Highway Code rule 275 says the safest place to stop on a motorway is a service area. If you cannot reach one safely, follow the breakdown steps in the smart motorway section above. Call us once you are safe.
How quickly can a mobile tyre fitter reach me on the northern or eastern M25?
We guarantee attendance but do not promise an arrival time. We guarantee attendance on every job we confirm (not on the Dartford Crossing itself or its approach roads), and where the police or National Highways are managing the scene we attend as soon as they allow access. Call 07960 200253 once you are safe, give us your direction and the last junction you passed, and we agree the price with you before we set off.
Do you fit tyres overnight near the Dartford Crossing and QE2 Bridge?
We answer calls 24 hours a day, including overnight. The Dartford Crossing itself (the A282, including the Queen Elizabeth II Bridge, the tunnels and the approach roads) has its own rules: only a constable or traffic officer may move a vehicle at rest because of a breakdown there (other than in a designated parking area), and repairs need their express permission. So our attendance guarantee does not extend there. If you are in danger, call 999.
I have run-flat tyres, can you still help if one deflates on the M25?
A run-flat can be driven a limited distance at reduced speed after losing pressure. The limit depends on the tyre model, and a deflated one may show no wobble or pull, so do not rely on feel. On the M25, leave at the next exit or pull into a service area if you safely can; otherwise follow the steps in the smart motorway section above. We guarantee attendance on every job we confirm (not on the Dartford Crossing itself or its approach roads) and, once the scene is safe, we can supply and fit a replacement tyre or arrange recovery.
Will the TPMS warning light be sorted after a replacement tyre is fitted?
Fitting a replacement tyre normally clears a TPMS warning caused by the pressure drop itself, once the new tyre is up to the correct pressure. If a sensor has been damaged or the light stays on afterwards, that is flagged at the time so it can be checked or replaced separately rather than left unresolved.
