Some time back I posted about fixing a set of FF 20 wheels. Right after that, I attempted to mount the tires on them. Well, today I finally got them mounted. It just took some warm weather to get those things to go on the wheels. Those sidewalls are stout. Anyways, they are mounted and basking in the SUN with 20 lbs. air in them. It took 30 PSI to get the first one fully seated. 40 PSI to get the second one. And that was with grease on both the wheel and tire bead. I think they will hold air just fine and if so, time to LOAD them.
