@78Buckshot that's a rare deal indeed! 10R22.5s won't fit in my wheel wells, the biggest I can do is 9R22.5 or 255-80R22.5; each is approximately 38.5" give or take .2" which is 2" taller than the 8.25-20s the bus rolled in on. The new tires might rub a little bit when going all the way to lock while parking, but that's a small price to pay for lower cruise RPM, and modern day driveability.
Really excited to get my rig rolling with new tires and taller rear gears.
