When a puncture can be repaired
British Standard BS AU 159 allows a repair only in the central repairable area of the tread, with a hole no larger than 6 mm for a normal car tyre, after the tyre has been taken off the wheel and inspected inside. A plug stabbed in from the outside, while the tyre is still on the car, is not a proper repair.
Costa Tyres removes the tyre, checks the liner for splits, and fits a patch-plug combination from the inside. That is the repair we do in Staines and on mobile puncture call-outs.
When you need a new tyre instead
- The hole is in the shoulder or sidewall.
- You drove on the flat and the sidewall is chewed or the liner is creased.
- There is more than one puncture, or the hole is too large.
- The tread is already close to the 1.6 mm legal limit.
- It is a run-flat that has been used with no pressure.
We would rather sell you one correct tyre than a repair that fails on the M25. If you are comparing tyre repair and tyre replacement, send a photo of the nail and the sidewall.
Mobile puncture repair around Heathrow
Airport roads collect screws. If the pressure warning has just come on and the tyre still has air, do not keep driving “to see”. Pull over somewhere safe and call +44 7771 363978. Mobile puncture repair covers Staines, Stanwell Moor, Ashford, Feltham and Heathrow hotels.
Slow punctures are often a leaking valve or a rim that is not sealing, not a nail. We check those before we condemn the tyre. After a repair we set the pressure and, if you want, book a tyre pressure check on the other three.
Questions drivers ask us
Can you repair a puncture at the roadside?
Yes, when the hole is in the repairable tread area and we can remove the wheel safely. Sidewall damage needs a new tyre.
How much is a puncture repair in Staines?
The price depends on whether it is a workshop job or a mobile call-out. We quote before we start. A repair is cheaper than a new tyre when the tyre is still legal.
Is a string plug enough?
An external string is a get-you-home measure at best. We repair from the inside to BS AU 159, or we replace the tyre.
Will the tyre be safe at motorway speed?
A correct tread repair on an undamaged tyre is designed for normal use, including motorways. A damaged sidewall is not.
