Apologies for crashing this thread somewhat - though I have been reading these forums for a couple of years - hoping someone might be able to give me some advice!
I'm doing this event tomorrow and am pretty much a newbie (don't worry, am starting at the back). Have just gone to give my bike a final going over and noticed on the back tyre a crack that runs from the sidewall to the middle of of the flat bit, though seems pretty stable - but worse, a semicircular tear of about 1cm in the tread - if I lift up the flap I can see the tyre wall under it - they are bontrager race lite hard case tyres, if that makes any difference. TBH I could have done 3 or 4 rides with them like that, or it could be new. Should I change it? I have a new tyre but are there any downsides to doing a long ride on a new one?
