This weekend I put a pair of 700x32 Marathons on Velocity Synergy rims.
One tire went on just fine, but the other seemed mishapen and took 3 or 4 tries to get the bead to seat. Later, about 8 miles into a ride it blew out badly.
I may have just gotten a bad tire, but I am curious if anyone else has had a problem like this. I don't think it was badly installed.. I've changed my share of tires, and haven't ever had this problem before.
