It may take a few more passes to "set" the tires. keep trying..
I run the exact same #'s and slicks, rim size as you. I have no slippage...

I'm on my 5 or 6th set of Hoosier Radials and have never had an issue. For curiosity, I put a paint mark on the tire that aligns with the valve stem on the last set. After about 70 runs you can see how much they have moved - not much at all. For the record - this is a 3400 LB A/SA Max-Wedge 64 Plymouth - mounted on 10" Weld Wheels w/ no special work on the bead - no adhesives - but always run with 21+ pounds of air pressure.

As referenced by others, I think the wheel width and higher air pressure are the key.

I've had this same issue for years. Tires would rotate 1/2"-1" on every pass. Hoosier 30x9, 10" wheel, 20lbs of air 3200 lb car. Swapped tires from side to side and they would move back to a point, sometimes one and not the other. Tried screws, then the tires would move and leak. My next move is to scuff up the bead area of the wheels, give the tire bead something to bite on. Sandblasting suggestion is a good one, I was thinking DA and 180 grit paper.

No out of balance issue yet. Going to break the beads & re-index to where they were initially balanced at.


I haven't tried over 20 lbs. air pressure yet. Might try 21, but they are crowning pretty good at 20 with that 8" rim.

That is why they should be on 10" wheels. They will hook harder, and run faster with more air.

If wheels are very old that could be a problem.Every time you have tires mounted the wheel changes very little but it does change.I have been mounting slicks for 35 years the older the wheels the easier the comeoff and go on.I use the spray permetex.Radials allways like more air than you would think.Dwight Allen

They were bought in early 1989 & have had many tires mounted on them.

Most everybody I know don't even check to see if the tires move. Just put the on and let them eat. Maybe I am just lucky idk. It might not be any big deal if they move a little bit.

My main concern is the tire/rim balance!
