Thank you very much for the info ;-)

British Tyre Manufacturers’ Association

Repair of SSTs

SSTs have specially reinforced sidewalls to enable them to perform when deflated for a limited distance and at a restricted speed. The distance permitted under these conditions may vary according to the tyre or vehicle manufacturer concerned.

When running in a totally deflated or significantly under-inflated condition the tyre’s internal structure is subjected to high stresses and hence may become weakened and permanently damaged, rendering the tyre unsuitable for repair. Unlike standard tyres, damage symptoms may not be visible with SSTs. As each tyre manufacturer may use different technical solutions to provide run flat capability, the views on repairing of SSTs varies across the industry.

Hence, reference should be made to tyre specialists or to the relevant tyre manufacturer for repair guidelines and to the vehicle owner’s handbook regarding the use of repaired tyres on the vehicle.

Prior to a repair being carried out the tyre must be removed from the wheel and given a thorough internal and external examination by a tyre professional. This is to ensure there is no visible structural damage that may preclude a repair.

The responsibility for the repair remains with the repairer of the tyre.

Also proper puncture repairs should be carried out in accordance with BSAUl59 regulations. Only a vulcanised plug patch should be used, which repairs the tyre to the required standard.

Hence for inspection and a 'plug patch' repair, the run-flat tyre must be removed from the rim.

I know mines wasnt even removed from the car, though it never ran flat or had tyre pressure indicator on. It was only because i heard it that i checked and seen it in middle of tyre. The tyre repair place is under 2 miles so drove straight, screw pulled plugged and back out.. never had any problems.

Not every tyre shop works to the industry standards. That is clear from your experience. National Tyre Distributors Association (NTDA) and BSAU 159 make it clear what is the accepted repair standard.

Quote:
The BSAU 159 standard states that tyres should be removed from their rims to be thoroughly inspected to ascertain their suitability for repair. The standard also defines appropriate repair materials.

For the proper procedure, an example from etyres....

Quote:
The first step, and one of the most important requirements of the BSAU 159, is to remove the punctured tyre from the wheel so it can be given a thorough inspection to check for its suitability for repair.
