I got the Mission rear mounted. When I got it I thought "Man, this is a heavy, stiff tire." My initial thoughts were confirmed when it came time to mount it. It did not want to pull down into the center and stay, even with my considerable bulk on top of it. Fought it for a good hour before heading out to get some bead buddies. Waited for morning to start again. Started with putting a heater on it. Used the bead buddies and added some strap clamps and blocks to push and pull it in. Toughest tire I've mounted. It also took quite a bit of weight to balance. It is nice to see a tire with an American flag on it.
