Repairing a tyre is not as straightforward as you first might think.
Our tyre repairs policy reflects that of the British Standard - BSAU159. The British Standard also defines limits to the location, size and number of repairs that can be carried out and suggests recommended materials to be used for the puncture repair.
Types of Damage
Tyre damage repair should only be attempted if the tyre has first been checked thoroughly. If the tyre displays any of the following characteristics, a puncture repair should not be attempted;
- Illegal tread depth (below 1.6mm across the central ĺ of the tyre tread throughout the entire circumference)
- Secondary damage - caused by the injuring object
- Ageing/deterioration of tyre rubber
- Bead damage
- Exposed cords
- Faulty/poor previous repairs
Inspection is vital - if you have any doubts about whether or not a tyre should be repaired, do not repair it.
British Standard BSAU159 also defines the requirements for safe minor car tyre puncture repair and its proximity to the sidewall. To remain compliant, we are only able to carry out tyre repairs to the central ĺ of the tyre (known as the minor repair area). If the puncture is situated outside of this area it is deemed too close to the sidewall to guarantee a safe and lasting minor repair.
Unfortunately we are unable to repair runflat tyres.
Runflat tyres have reinforced sidewalls which means they can be driven on for a short time after picking up a puncture allowing you to travel to safety or to your nearest tyre fitter. Unfortunately, when a runflat tyre picks up a puncture itís hard to tell if the structure of the tyre wall has been compromised because the punctured tyre could have been driven on for an excessive amount of time or at unsuitable speeds (over 30mph) but the added strength of the runflat tyre can mask this damage. For this reason, we cannot carry out minor repairs to runflat tyres as the tyre may no longer be safe to use.
