I bought a new Dunlop 952 rear tire for my bike last fall but due to too many honey-do's I haven't had time to mess with getting it mounted up until late last week. Got the tire on without pinching the tube and started my standard ritual of air it up without the valve stem to help seat the bead, let the air out, then air it up to about 25 lbs and let it sit overnight to check for leaks and I was having a helluva time getting the bead to seat on both sides of the tire. I finally got one side to seat by airing up to 35lbs and letting it sit overnight but one side is still being a stubborn SOB. I've aired it up to 40lbs, left it sit, bounced the wheel about a bajillion times, aired it down and bounced it, baby powder on the rim, etc and still no love. Anybody have some good tips for a REALLY stubborn bead other than yank the tire off and put a different one on?
