ok. i'm going to re-deflate the rear tire again, check it (time permitting), but definitely make sure i work it around at low pressure before fully inflating. my two cents about the above ethics business is that this later advice did not come out until well after the +1 [\thread], so even if everything was known, not everything was said.

someone mentioned working the tire closer to the rim. how exactly does one do this? it was also said to "squeeze" the tire at low pressure-- wouldn't that push the tire towards the center of the rim/wheel not towards the rim? i will look at it under low pressure and see if i can get it to seat correctly. maybe a slicker style rim tape would help vs. the more fabric type? to help the tire move freely to the outside towards the rim?

but anyway, seems like it's a problem re: mounting. i'm headed down to remount that thing now. if i never repost to this forum, it blew under high speeds on today's ride.
