Ah.. I think I'll wait to be stopped like you were and tell them I'm waiting for instructions.
Did I tell you why I'm sour Gfalls? The family car was failed last year for "canvas" showing on one of the tyres. Canvas? On a modern tubeless steel wire enforced tyre. I thought it was a wind up. but no. I tired to tell the lad that canvas has not been used in tyres since he was a young lad. Anyway, conveniently enough there is a tyre place 2 doors away form the NCT centre... sweet eh?
passed the second time, he didn;t even check was the tyre replaced. I couldn;t wait to get back for my next NCT.
