[quote] It's probably the same thing as running 12.5" tires on 10" rims, which used to be pretty common.


That's what I have now, and it is a problem when airing down. My tires slip on my rims if I air down below about 15 psi. I haven't lost a bead yet but it throws my balance off every time I air down. Last time I was wheeling I marked my valve stems with a marker and all 4 tires slipped. This was at the start of a trip;

By the end of a week some of the tires had slipped 6-8 inches on the rims.
