When can you safely repair punctures?

Cuts, breaks and abrasions to the tyre casing can penetrate deep into the inner fabric of the tyre and can be extremely dangerous - 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. Puncture repairs should be carried out in accordance with BSAUl59 regulations.

Only a special vulcanised plug patch should be used which repairs the tyre to the required standard.Don't ever let anyone else attempt to repair your tyre to a lesser standard - it could prove fatal in the event of the repair failing at speed.

The main points of the BSAUI59 regulations are:

Tyres can only be repaired in the area marked 'T'. For tyres rated 'V' and above, only one repair is allowed.

NOTE: NEVER FIT AN INNER TUBE WITH A TUBELESS TYRE EXCEPT ON A TUBE TYPE WHEEL
