It wasn't just one rim. I've had trouble with at least 3 different rim brands. The one incident where I blew out 4 tires in one day occurred on a Mavic A719 front rim and a Ritchey OCR rear rim. None of those blowouts occurred on tires that had been pumped above the recommend pressure which is 90 psi. The tires were 37mm Continental Touring Contacts with a folding bead. I didn't experience any more blowouts for the rest of the trip...this happened on the first day...but I had to run my tires at 60 to 70 psi and ride very, very, very carefully around any kind of holes in the road. I also carried 6 (six) tubes for the rest of the 2 week tour that I never used.

I've used many other folding bead tires before and since on many bikes in many different applications and widths from 23mm fast tires to 2.2" mountain bike tires on 17mm rims and never had any other brand blow off the rim unless I mounted the tires wrong. And any blowoff that happened did so during inflation not miles after the tire had been mounted.

Personally, I would use...and have used...a Bell folding tire from Helmart before I'd use a Continental.
