Dry Lube For Tire Mounting?

[GreggT]

Guys...I've had this problem of my Sport Cups rotating on my Turbo hollow rims (on the track).....as you might expect, the rear wheel spins forward in the tire and the front is just the opposite.

The fellas at the Michelin truck thought it was a curious problem, and after confirming there were no tire-rim size issues suggested the mounter may have used a lube that kept heating up and slipping.

I don't think that's the case, my shop is Kelly Moss Racing and they have even roughed up the rim for me and then remounted....and I believe either use Sliptac or Rubilite (sp?) for mount lube.

Has anyone had this issue or experience w/any lube roduct that gets the tire on, but doesn't help it move later?......TIA.

A local tire/alignment shop puts on a Porsche tech session for us once or twice a year. He has seen the same thing on Vetts. He said that once it gets hot the lube bakes out, so you are supposed to take it easy until then or the tires can rotate on the rim. I do not know what they use.

Appreciate the comment but 'taking it easy' on the track is not really an option (and if you do, you're not heating up the tires).

Last time out, my tires were up to temp on & off all day and we respun all four at the track (because they had slipped to the point of being way off).......back on the track and they continued to slip.

I'm running Mich recomended pressures.
