What is a good replacement tire for the XX'S stock rear wheels. The dunlops that come from the factory are garbage is my opinion. I was rideing down the canal bank and caught the right rear on a rose bush, punctured it right where the tread meets the sidewall. Can patch it...of course. The thing that sucks the most is...the bike only had 1.5hrs on it. $131 later got it replaced, needless to say...I aint buyin dunlops as replacement tires.
