M/T ET drag radials slipping on rims #2653082 05/07/19 05:36 PM 05/07/19 05:36 PM

That didn't stop even after about 10 runs. One of the tires started leaking air at the bead after a run, so I dismounted the tires. The beads weren't damaged. I read that some people are glueing the beads to the rims with Permatex High Tack. So I did that when I put the tires back on. The tires are still spinning about an inch on the rims after 7 runs with the High Tack. I feel like I want to put bead screws in, but everyone (including M/T) says you can't do that on radials. So what's a poor racer supposed to do? Bead locks are expensive. Why is it that I can't use bead screws? Everybody says so, but nobody ever says why

One or two guys had ripped the bead out of their radials with screws while others reported that they had done it for years with no problems. https://www.yellowbullet.com/forum/showthread.php?t=144867 https://www.yellowbullet.com/forum/showthread.php?t=159200 Master, again and still

It’s a step by step process and the best results take 2-3 days. There is no way in heck you should have issues with a 9 inch tire if you do the proper steps. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

More than that and they spin I suspect it's the low air pressure you use. Most radial users I know run 18-22 psi and the higher pressure seems to reduce the tire rotating on the wheel. Maybe your chassis settings aren't optimized for a radial, which requires you to run lower pressure as a Band-Aid for the chassis.

Maybe your chassis settings aren't optimized for a radial, which requires you to run lower pressure as a Band-Aid for the chassis. That's exactly what I'm thinking. I've ordered mono leafs and shocks from Calvert. Hopefully that will help. Mazzolini thinks so. The glue cured on the rim/tire for over a month before I raced. I put plenty of High Tack on both the rim and the bead and waited until it tacked before joining them. I don't think I did anything wrong.
