apologies, the search never happened. google fu/foo/fool is weak. +1 new front sedona knobby, looks round to me +2 hours on the trucks bed liner in the sun +1 drz front wheel (cause the back would be difficultererer) + 1 gallon dawn + water, or wd40, or motor oil, or well, i've tried everything in the garage now +85psi = the damned thing still won't set in the bead as it should. i've a stack of tires taller than me that didn't have this problem. i've gone up/down on the pressure but 85 psi was my limit. i really don't want to get impaled. i've hammered on it, dropped it from shoulder height, rode it at 30 mph with 8psi, rode it at 70mph at 20 psi, kicked it and used all my really good cuss words. it will not seat. ideas not covered already ? (yes, the tire is in the rim lock correctly, no it's not tightened yet) (yes, i cleaned the rim/bead) (yes, i put a 21" tube in, not a 26, or 700c, or whatever) ok, fire away.
