Tire screws

[Cornpatch MO]

usta be everyone put screws thru their wheel rim edge into the tire bead , to keep the tire from slipping on the wheel. I don't notice that so much anymore. At what point do you need something to stop tire slip on rim? For instance a 8- 9" slick and about 400 HP. with 3:55 rear gear and a clutch or tranny brake. I been out of the loop for about 20 years- drag raceing.........................MO

Just curious. Why do sometimes a post to General tech appears on recent posts and sometimes not? What qualifies for recent post? Recent posts are what I first go to everyday...........................MO

not sure if they did it when they would run low tire pressure and "wrinkle" the tires off the line to keep the rim from spinning inside the tire.

Mark the tire with a dot or something near the tire valve.If it moves you need to use rim screws:icon_bounce:

Don't see screws much anymore because beadlocks have become more common ??

Few years back my brother was running a low 10 second demon,foot break car.Didnt have the screws and never a issue.

I've also seen guys just run them on the back side.

Back in the old days (60s & 70s) NHRA had a 7 inch tire treadwidth rule in stock and I believe superstock classes. The only way to get enough traction with these narrow slicks was to run extremely low pressures and really wrinkle 'em up at the launch. Made for kind of a hairy ride at the top end as the back of the car would start to dance around.. At these low pressures the wheels would just spin inside the tire hence the sidewall screws. Slicks being run now are not only wider, they are better in every way. They are designed to be run at a higher psi and still give excellent traction so most don't need sidewall screws. That said,it's a good idea to mark the tire and wheel to make sure that the wheel isn't moving around inside the tire,
