At its nearest measured point, the A406 North Circular is about 0.1 miles in a straight line from our only base at Brent Cross, NW2. We give you an arrival time when you call.
Replacement of a cut, bulging or split tyre once the car is safely off the main road and parked somewhere safe.
If a tyre fails and the car can still be driven safely, get it off the main road into a side street or a car park where the owner allows it. On a busy road or dual carriageway, do not try to change the wheel yourself; call your breakdown cover, or 999 if the car is somewhere dangerous. We never work on the carriageway of a motorway or main road, on a hard shoulder, in a smart motorway emergency area or on a slip road.
The North Circular has no hard shoulder anywhere between the Chiswick roundabout and Beckton, and Transport for London runs the whole road as a red route: no stopping on the carriageway, slip roads or underpasses except in a breakdown.
We cannot stop or work on a red route; the car needs to be on a side street or private ground first.
The road's junction list and the full Highway Code steps are on its main page, under Related pages below.
A tyre with a cut, a bulge, a split, exposed cords or sidewall damage is not safe to repair, so it is replaced. A bulge means the inner structure is broken and the tyre can fail without warning, so it is safest not to drive on it.
The fitter fits the new tyre at the car and balances the wheel. The fitter also checks the wheel for damage from the same kerb or pothole and looks at the tyre on the other side of the axle: tyres on the same axle must be the same size and type, and should have a similar tread depth. If both need changing, we tell you before any work starts.
When the car is parked somewhere safe and legal, such as a side street near the exit or a car park where the owner allows it, we can come to it. Tell us which junction you left at and where the car is now.

A tyre that has burst, split or been cut on the sidewall is beyond any repair, so the answer is a new tyre. What matters first is getting the car to a safe place without driving on the damaged tyre for longer than you have to.
A bulge on the sidewall means cords inside the tyre have broken and air is pushing the rubber outwards. It can fail without warning, so the tyre should be replaced rather than driven on.
Cuts deep enough to show the cords, cracking around the bead and damage from a hard kerb strike are also replacement jobs.
If a pothole caused the damage, note the exact location, photograph the hole and the tyre, and keep the receipt for the new tyre.
Claims go to whoever looks after the road: National Highways for motorways and major A roads in England, and the local council for most other roads.
Hold the steering wheel firmly and keep the car straight. Do not brake hard: ease off the accelerator and let the car slow down, then brake gently once it is under control.
Indicate, move to the side when it is safe and switch the hazard lights on.
Call or WhatsApp with where the car is, the registration and the tyre size from the sidewall. A photo of the damage helps find the right replacement.
You hear what the job involves and the options for your car. Nothing is booked until you say yes.
The fitter comes to your home, your workplace or a safe place to park, raises the car on a jack and does the job beside it.
Before the fitter leaves, the wheel is checked for security and the tyre pressure is set to the maker's figure.
“Arrived and was very kind and polite. Reassured me about changing the tyres and was quick and attentive straight away.”
“Excellent service from start to finish. He came out quickly to help my mum change her tyre and was extremely friendly.”
Cars and light vans need at least 1.6 mm of tread across the central three-quarters of the tyre, around the whole circumference.
For a car, each illegal tyre can bring a fine of up to £2,500 and three penalty points; the maximum fine for a van is higher.
Push a 20p coin into the main grooves at several points around the tyre. If the outer band of the coin is visible, the tread may be close to the limit and should be measured properly.
A tyre is also illegal with a cut longer than 25 mm or a tenth of its section width, whichever is greater, that reaches the ply or cord, a lump or bulge, exposed cords, or the wrong size or type for the car.
The last four digits of the DOT code on the sidewall give the week and year of manufacture, so 2319 means the 23rd week of 2019.
Rubber hardens and cracks with age even on a tyre that has done few miles, and many tyre makers advise replacing any tyre ten years old or more.
There is no fixed figure that suits every car, so the price is built from a few things and told to you before you decide.
The price is given on the call. The price is the same at any hour. Asking for a price does not commit you to anything.
When you compare prices, compare like with like: the same brand and pattern, the same load index and speed rating, and whether balancing and a new valve are part of the job.
Tyre blowouts: causes and prevention
Most tyre blowouts are preventable. Here are the main causes, the simple monthly checks that stop them, and what to do if one happens anyway.
A blowout at speed is frightening but survivable if you react correctly. Here's exactly what to do, why braking is dangerous, and how to prevent the next one.
You don't always need four new tyres. Here's when you can replace just one, when you should do a pair, and when all-wheel-drive means replacing all four.
Get the car somewhere safe, send a photo of the damage and the size, and the new tyre comes to the car. Tell us what has happened and the make and model of the vehicle.
