First time: BIG ratchet straps (2), valve core removed, many a hit from the Cheetah.
A couple of days ago, a slathering of this stuff and it aired right up . . . . no straps, no cheetah! JTM Products, Inc. - Products - Tire Mounting Lubricants
Again . . . let me say that this is the best $9 that you could EVER spend.
The tire, once inside the rim, will seat itself with only an air hose. The bead just slides right on, it does not even "pop" into place.
I am sure it is cheaper than ether . . . . certainly safer!
