This weekend I had a second "tire explosion" while 15 miles from home. My Roubaixs original tires lasted 2000 miles and then the rear went out on me. In the last 6 months or so I have replaced the rear tire TWICE with similar Specialized Roubaix tires. Both have failed and at $60 a pop it aint funny anymore.However, could the problem be that I am over-inflating? The tires are rated to 8 BAR and I always pump approx 7.7 BAR into the tires before a ride. Now, I am in the 280lbs so I am wondering if the weight and the close to max pressure are the issue. Could it be that when I hit a pothole or similar that the tire pressure is increasing beyond the limit of 8 BAR and weakening the tire?
It was a little humorous I guess. Early Sunday morning, and as I rode past the church in Carnation, WA, BBBBAAAANNNNNNNGGGG - It literally sounded like a gunshot going off. Birds flew out of the trees, church-goeers were startled and the Clyde in his lycra was sheepishly apologising and pointing at the tire. My wife was thrilled that she had to get out of bed and come get me on a Sunday morning
Any thoughts on tire pressures for us bigger guys?
P.S. Enough of the $60 tires. Just bought a pair of Nashbar Road 2 tires for $15 a piece. Good reviews too.
