i was at a petrol station one night & there was a little curtainside wagon with the garage air line poking in thru the back doors... i went to see how long he'd be as i needed it & there was this bloke pumping up the tyres on michael schumachers 1994 championship winning benetton(one of them) as they apparently move about on their wheel straps unless you pump the tyres up a bit....... he was off to a show with it... it was very nice.....
