Gentlemen,

My tires keep slipping on the rims when driving on the track. As you would expect, the rear tires slip from accelleration and the fronts from braking (opposite direction slippage). Last time, when the rears were 180 deg. off where they were when they were balanced, I removed the weights and significantly improved the shaking.

The best I've come up with is to mount the tires dry without lubricant.

When at the track I run Hoosier R6 255/35 and 315/30-18 (I know the front tires are smallerbut the width is desirable and I am keeping the fingers crossed on diff longevity. At the track I lower the boost to 1.1 bars using a manuakl boost control. In addition to making the car last longer the torque curve is much nicer.

Several of you have more horsepower than I do so you should have this same problem, or maybe a solution. Good ideas how to stop the tires from slipping on the rims would be welcomed.

I tried everything including dry mounting and using 3M Professional Strength spray adhesive on the tires. They still moved about 1-2" per track session. Every track day, I would flip the wheels left to right on the car which slowly rotated the tires back where they started. It was still annoying as I hate it when wheels go out of balance. I got fed up with it and last year and had several sets of track wheel built that had knurling on the wheel bead. This locks the tire on the rim and keeps the tires in place. Works beautifully. Tires don't move a millimeter. The OEM wheels on a Nissan GTR use this same technology. Here's what it looks like. Finspeed is the only wheel manufacturer that has this as an option on their wheels.

I've found letting the tires get 'hot' a couple times before applying real torque, engine or brake, gets them attached well to the rim. I also find using soap, instead of other substances, to mount the tires helps as well.
Ultimately, the knurling is the best/right way to do it..

Mounting tires using rubbing alcohol in a spray bottle works very well. You spray both the tire and wheel beed and the alcohol makes it very slippery yet evaporates very quickly so by the time you are ready to seat the bead the tire and wheel is dry and you are effectively mounting them dry at that point. I also always wiped the tire bead down with acetone to get rid of any release agent. I never had much luck with the hairspray method but the 3M adhesive definitely helped.

GM ran into that on one of their new uber cars. Their solution was to sandblast the inside edge of the rim to rouch up the surface. Mask the wheel off and use something somewhat aggressive and you might be able to do the same thing? If you look around you can probably find pictures of what the wheel surface looked like - it was one of the new track oriented Camaro I believe.

Sandblasting is a bit of a double edged sword because you are effectively taking away material from the wheel bead and thus slightly loosening the tire to rim fit. You have to be careful not to be too agressive bead blasting. I have a friend that took his CCWs, roughed up the wheel head with 40 grit sandpaper, and then sprayed the wheel bead with epoxy based paint. He then lightly dusted the wet paint with very fine sand thus giving it a rough texture after it dried. It worked..

Yup, anything that allows the tire to slip over the beads/seat and doesn't leave a residue. It's definitely harder to get the tire on, but I know when I do it this way it's generally a 90% success.
...some shops use tire dressing/'armour all' as the lube which naturally doesn't work well for us...some default to the rubber sealer crap no matter what, horrible...

Good info. Thanks guys

If you're not using the tires for too many miles you might be able to use Dyna Beads. They're small ceramic ***** that roll around inside the tire always keeping it in balance. You won't need weights and it won't matter if the tire slips. Used mostly on motorcycle/truck/rv tires.

I think the problem with using them on track tires is the softer inside liner getting beat up by the ceramic.

was going to mention the beads as well, but don't have any real experience with them in a performance application...
Anyone here with high-speed and/or track time with them???
