Cuts, breaks and abrasions can penetrate deep into the inner fabric of your
car tyre which can be dangerous, even capable of causing high speed blow-outs. However, penetration of the tread by a nail or shard of glass or metal can often be safely repaired.

At National Tyres and Autocare only a special vulcanised plug patch is used which repairs the tyre to high standard in accordance with NTDA and BSAUl59 regulations.
