In attempting to mount a motorcycle tire, I was unable to properly seat the beads. While the tire inflated and held air pressure, it failed to easily seat across identical points on both sidewalls. When I did eventually get the first, the second side continued to be troublesome. Before the first bead set, that area of the tire was hard to compress together. It seemed that the beads stayed close together there. Rotating the tire on the rim showed that it was the same spot on the tire that was always affected rather than a spot on the rim. The following were tried:
- Various inflation and deflation attempts.
- Lots of Windex.
- Moderate amounts of dish-soap-like tire lube.
- Spooning the tire completely off the rim, then back on it.
- Hitting the inflated tire with a hammer.
- Bouncing the tire off the ground when inflated and when deflated.
- Leaving it sitting overnight with up to 70psi in the tire.
One bead finally popped on at 80psi after the first 2 hours of effort -- and the shockwave made me temporarily deaf. Since then, I kept it to 70psi or lower. I worked on it for a total of five hours. I finally gave up and brought it to a friend's shop. I believe he pumped it up to the full pressure of the shop compressor: over 130 psi. He also tried the hammer trick and some spray-on tire lube. We finally seated the second bead with 60psi and bearing grease on about half the rim.
Are there better approaches to this madness? A certain kind of tire lubricant that will works best? I know the catch with the grease is that it won't dry and will remain in a lubricating state until I clean the rim for mounting the next time -- though I really doubt that damn thing will actually spin on the rim.
