CityGrip provides 24/7 mobile tyre change on the M20, covering J1 to J13 including the hard shoulder and the emergency refuge areas on the smart-motorway sections. We fit your spare, supply and fit a replacement tyre if you have no spare, deal with locking wheel nuts and seized wheels, or recover the vehicle if the tyre cannot be changed safely on a live carriageway. Motorway mobile tyre change runs from £250 to £750 depending on the tyre and vehicle, with the exact price agreed before we set off. Call 07960 200253 for a mobile tyre fitter near you on the M20.
The M20 is Britain’s route to the Channel Tunnel and Dover, dominated by freight and prone to Operation Brock contraflows when the ports back up. A flat tyre in a narrowed contraflow with lorries either side is a genuinely dangerous place to be. Our tyre vans and network cover the M20 from the M25 down to Folkestone, reaching your junction with the right kit.
M20 mobile tyre FAQs
Do you cover the M20 to the Eurotunnel and Dover?
Yes. We cover the M20 from Junction 1 at Swanley to Junction 13 at Folkestone, including Junction 11a for the Eurotunnel and the Dover approaches. If you have a crossing booked, tell us when you call and we will give a realistic arrival time.
What if Operation Brock is in place on the M20?
When Operation Brock is deployed the moveable barrier changes the lane layout and can remove the usable hard shoulder, so a flat tyre is more dangerous. Tell us Brock is in place, which side you are on and the junction, so we route to you correctly.
What do I do if I get a flat while Operation Brock is running on the M20?
Operation Brock narrows the lanes and removes the usable hard shoulder, so stopping among queuing lorries is dangerous. If you can, reach the next exit. Tell us Brock is in place, which side of the barrier you are on and your junction, so we route to you correctly.
How much is a mobile tyre change on the M20?
Motorway mobile tyre change runs from £250 to £750. It costs more than an ordinary roadside tyre change (from £90) because it is done on a live, high-speed carriageway with the correct warning equipment and safety procedures. A common tyre on a standard car sits at the lower end; a large, low-profile, run-flat or 4×4 tyre supplied at night sits at the upper end. We agree the exact figure on the phone before we set off.
Can you fit a tyre if I have no spare near J1 Swanley & M25 on the M20?
Yes. Most new cars carry no spare, only a sealant kit, which cannot fix a sidewall cut or a blowout. We can supply and fit a matching tyre at the roadside near J1 Swanley & M25 where it is safe to do so, or recover you towards J7 Maidstone services if it is not.
Should I change the tyre myself between J1 Swanley & M25 and J13 Folkestone & Dover on the M20?
No. Changing a wheel anywhere on the M20, whether that is up by J1 Swanley & M25 or down towards J13 Folkestone & Dover, is one of the most dangerous things you can do on a motorway. Get everyone out of the left-hand doors and behind the safety barrier, and call us. If you are stuck in a live lane and cannot get out safely, stay belted in with your hazards on and call 999.
How do I tell you exactly where I am on the M20?
Give us 'M20', the last junction you passed (for example J8 Leeds Castle), your direction of travel, and the number on the nearest blue marker post or the driver location sign on the verge. That pins your position to within about 100 metres so we reach you quickly.
Can you change tyres on vans and 4x4s on the M20?
Yes. We change tyres on cars, vans, 4x4s and light commercials anywhere along the M20, and carry the equipment for larger wheels, locking nuts and wheels seized to the hub.
My car has run-flat tyres, do I still need you on the M20?
Run-flats let you keep going a limited distance at reduced speed, typically around 50 miles at up to 50mph, but that is a get-you-off-the-M20 measure, not a repair, and many run-flats cannot be repaired at all once run flat. Leave at the next exit if you safely can, then call us to supply and fit a replacement or recover you.
My tyre pressure warning light has come on near J3 M26, can I carry on?
Treat it as a warning that something is wrong. A slow puncture can become a blowout at M20 speeds. Ease off, leave at the next exit if you can do so safely and check the tyre. If it is going down, do not carry on, get somewhere safe and call us.
What is the legal tyre tread depth for driving the M20?
The legal minimum is 1.6mm across the central three-quarters of the tread and around the whole circumference, the same limit anywhere in the UK. Below that you risk a fine and penalty points for each illegal tyre, and grip and wet braking fall away long before you reach the limit. Any tyre we supply and fit is legal and correctly matched to your vehicle.
