If you have a puncture you may be wondering whether you can salvage it by having it repaired or whether you need to buy a new tyre. In some cases you can repair a puncture however it is unlikely due to the following factors.
The size of the puncture :-
If the puncture is minor and has occurred in the centre of the tyre you may be able to get it fixed. If the puncture is bigger than 6mm in diameter you cannot legally repair it. Small punctures caused by sharp items such as nails can often be repaired as the damage is normally quite small. If you've been unlucky to drive over a larger item then its most probably caused irreparable damage.
The type of tyre :-
Run flat tyres are designed to drive with a puncture for limited mileage usage allowing you time and distance to get to a garage rather than being stranded at the side of the road. It’s important to get any punctured run flat tyre replaced.
Where the puncture happens :-
Normally punctures can be repaired if they happen toward the centre of the tyre. If it’s near the sidewall more often than not the tyre would need to be replaced. The sidewall takes the burden of the weight of the car and any repairs weaken the structure. Repairs wouldn't last long on the sidewall and its recommended to get new tyres in this instance.
