Radial Slicks Moving On Rim
 

I have 20 - 25 passes on our new Hoosier Radial Slicks (9x30) mounted on 8" wide Cragar Superlights. The slicks move about a 1/2" after about 5 passes. The Driver's side is the worse. I rotate them to try & re-index, but of course that's not going to work. The rim bead/tire bead were cleaned with acetone & mounted dry on the 1st 10 runs.

Next, I broke the beads clean them again. Then I glued them using 3M black weatherstrip adhesive. They are still moving on the rims. I don't know what to do & don't want bead lock rims.

The car weighs 3100 lbs. with driver. It has a pump gas 434 Chevy 630 hp/600 ft. lbs. torque. 5800 stall, 1.76 glide & 4.10 rear. Runs 10.0s - 10.40 depending on tune & track with mid-high 1.4 60's.

Would like to here some suggestions.

I forgot we are running 18-20 lbs. air pressure.

I clean the rim bead area then just use Permatex High Tack gasket sealant . Inflate to around 25-30 psi and let sit for a couple of days then good to go . Only ever had to redo this once . Bugger to clean the rim when replacing tyres , I use paint thinner
Good luck

I had the same problem with the Camaro when running 17psi. Went to 20psi and has not moved since. It's a given I don't have the tq/hp your car does tho. Our rims are 10" btw.

put screws on them!

Should be on 10" wheels. When I ran 9" Hoosiers, on 10" wheels, I used 24 to 26 psi. You will use more air on wider wheels. Every radial I have used liked wheels 1" to 2" wider than the tread area. With the air needed for the wider wheels, it has always been faster, but with the added air my tires never slipped. No glue or screws on any of mine, just mounted clean and dry.

I sandblast the bead areas of the wheel.

Thanks guys!


Sounds like I need wider rims & more pressure. I'm not putting screws in radials.

We're their any adverse effects from the slicks moving on the rim.

Mine hooked harder, ran quicker on wider wheels anyway.
