Thanks for taking a look. Here's my question:
The wheel (without a tire mounted) was accidently dropped onto concrete from a height of 6'. This caused a very slight flattening of the rim at the point of impact, measuring a half inch at most. Otherwise, the wheel is round and true, according to the truing stand. The flat part is barely noticeable by eye, but can be felt by hand, and is obvious on the truing stand.
Mounting the same maxxis tire on this rim at ~110 psi resulted in the tire bead coming off the rim while riding. The second time it happened, it resulted in a KABOOM, shredding the bead and the tube. The rubber around the bead exploded, revealing the threads. I am confident that the tube was not pinched and the tire was seated correctly, as best as i can tell. Running a Continental tire on the same wheel at ~80psi caused no problems on a flat 50 mile ride.
My question: Is the slight bend in the rim causing tire failure at high pressures, or was the failure the result of a defective tire?
Thanks for your insight in advance.
