something that Jeepers due to help out beads that get mud and crap in them, or are leaking. statically overfill the tire to slightly less than ridiculous, and then set it back to normal, then take it for a drive.
Just an idea. other thing you can do it unmount the tire, clean the bead and seat surface and install again.
They strap you down into it to the point of loading up your suspension. then the drum itself is a knurled surface which is pretty grippy. I don't think i have ever been to an dyno even where a truck has spun it tires on it, and the ones i see online are always 1200+ hp.
