Tires were my job on the team, before setting tire on rim I checked for spots the tire bead could hang up on & if needed file them down. Before beading the tire I'd spray the snot outta the area the tire had to slide over. Thought about getting some of that gel Docs use when checking yur prostate, man that stuff is slippery If tire didn't bead up by 20lbs I took it back down & lubed it some more
