so this is a dumb situation. I’ve changed countless tires with no issue, but this wheel for my new front end will not seat a bead on any tire. I’ve tried two different tires now. Here is a run down of the tricks I’ve tried: Various lubes Over 100psi Leaving tire in sun and heated with heatgun Sit over night over inflated. Hammer on tire lightly and over inflated Ratchet strap around tire. Bounce tire lightly and over inflated. Remove /reinstall tire countless times. Inspect and polish/sand any imperfections in the rim lip. Lightly and over inflated ride the bike a few hundred feet. My question is could the rim itself be causing this? It’s an aftermarket “pro-wheel” rim laced to a RM250 hub. I’ve trued the wheel to within 1-2mm run out on each axis. About as good as ya gonna get being a used wheel, and my stock DR wheel was worse and held tires fine. Ima gonna 2nd amendment all over this wheel soon.
