Drag radial spinning on rim??
 

I posted this question on another forum but have not had any luck on suggestions or advice so I'll give it a shot here:

Im running a M/T 28.0 / 9.0R 3354R tire on a 3400 pound Nova. Car runs 11.70 in good air 11.90 in the summer.
I have had the issue of the slick turning on the rim.
My wife drives this car primarily and as it has became quicker and quicker I have started to have fears of the tire deflating du to the tire movement on the rim.
I have tried some RTV between bead and rim but with no success.
I tried adding rim screws, and it did stop the rotation but the car has slowed .3.
I called M/T and was told the rim screws are a bad no no on the radial tires.

Has anyone else had issues like this?
If so how/what have you done to stop it?

What tire pressures? Trans/ratio?

400 TH 2.52 low gear 4:11 rear gear
8" wide rim 16 psi

Spins both off of foot brake as well as TB

When the tires are mounted you cannot use lube, only water, RTV will not help

We run the M/T PBRs 29.5x10.5 on a 9" wide rim. The car is a 3200 lb. Camaro runs high 5s 1/8th & high 8s 1/4 mile. They do move about 2"s over about 50 runs. We leave off a transbrake & 60' in the high 1.20's - low 1.30s.

IMO, you're not running enough pressure. We started around 18 lbs. & are at 20 lbs. now to help slow the slip.

Get rid of the rim screws, M/T is right!

I have double beadlock rims now but haven't been to the track on them. I'm going to lower the pressure back down around 18 lbs. again.

With a 11.70 car I?d go up to 22 lbs?you?re probably wadding up the tire around the narrow rim. You can slow-mo video to see how the tire is reacting. More pressure you use and hook the faster you’ll go.

To all that have replied.
Thank you for the advise.
I'm getting tires discounted tomorrow to clean all the crap of and weld the holes shut.
Will try more air pressure next time out.

While you are at it, sandblast the bead areas of the wheels.

Re: Drag radial spinning on rim??
 

totally unnecessary. I've run radials for 2 decades without once ever "spinning on the rim"

All that required is the rim's and tire's bead is cleaned with acetone/Lacquer thinner, brakekeen, etc. and them mount them dry. IF they move at all, it will be minimum in the 1st few hits

Just to add another question to the group here.
long as the rim screws do not tear up the bead, how are the rim screws any different from a beadlock wheel?
