Got my new rear tire installed today, greased tire bead yesterday and let it sit, installed tire on rim today ( greased rim). Put 50 lbs of air in, slowly, let it sit in front of space heater to warm tire. Put 10 more pounds in and let sit in front of space heater for another 30 minutes, POP! Both sides seated. Quickly decreased pressure to 10lbs. Hope to get it installed Saturday or Sunday and try it out. Prior to install measured bead (exactly 14 inches), no trimming just a little patience.
