Help me narrow down the problem here. New bike, pumped the tires up to mid-range of sidewall's recommended specs (55lb pumped the day prior, 65lb max spec). After a good two days of thrashing on trails the front tube popped. I'm 220 lbs and the tire felt like it had just enough give to be comfortable and turn well on pavement.
Was the tire pressure too high for aggressive trail riding? Or should I be looking at the cheap Specialized tubes/tires/poor LBS build quality as the problem? I'll be taking the tube/tire apart for inspection today, didn't have the heart to check it yesterday as the bike is a day old and I was tired
