After using Tyreweld, you should drive to allow the foam to make it’s way round the whole tyre and find the puncture. You will then need to repair the puncture permanently, and we’d recommend visiting a garage for this as they’ll check to make sure the tyre’s safe, legal and roadworthy. The Tyreweld foam will wash out easily allowing the mechanic to carry out his repairs.
Tyreweld causes no damage to tyres and can be easily cleaned out prior to a professional repair. However it might be that on inspecting your tyre, the repairer has found other damage which makes it unroadworthy. If this is the case, ask for details so you know why the tyre is being replaced.
