While sitting in my living room I hear what sound like a gunshot coming from the garage. Uppon investigation I see the front tire blown off the front rim of my 2007 Cannondale touring bike. Rims are DT Swiss TK 7.1 with Schwalbe Marathon 700 x 35 tires. I keep them at 85 PS
There is no vilable damage to the rim and the tires have just over 1300 miles (tread still looks like new). Appearently the bead becam unseated.
Is there anything other than defective tires that would cause this to happen?
