Just received a wheelset and tires in the mail today from ebay. Tires are used Continental Grand Prix. Noticed a tear in the sidewall, contacted the seller about it. My main question is, is the tire safe to ride or is it repairable? It's not bulging but doesn't look too good. I put it on the rear wheel.
I know there are probably lots of threads like this but as with bent frames it's always a judgement call.
