Ouote,
"but a tyre that has had a puncture, will have been run flat, even for a short distance. Tyres are not designed to be run flat, and damage can occur in the sidewall from being run flat"
Not really people spot nails in tyres in there garage, take off the wheel there and take it to the tyre shop or it's a slow puncture and only loses 5psi a week..
Not defending the decision to buy punctured tyres off ebay because thats just really scraping the barrel, as said you can get tyres like Maxxis pretty cheap and a brand new maxxis if far better than a 3/4 part worn punctured Pirelli Diablo Supacorsa.
I mean you you wouldn't buy piss of a tramp for 50p a ltr rather than spend £2.50 on a pint of cider at ya local?
