I was told by the tech guy at our track,that if you run with less then 15 lbs of pressure in your slicks you need to use screws.I dont know if that is the rule for nhra but that is what i was told.

You can see that the wrinkle is pulling from where the screw is on the wheel.






5 screws around the diameter of the wheel will make for large paddles, but fewer paddles (4 paddles)






this doesn't compare with my pic showing NO screws at all. somethings not right with this theory.

not exactly sure what you are talking about ? what yours shows is a little low on air pressure, but not real bad

I run 9 x 28 M/T's with tubes on an 8 inch rim with 18 lbs of air. They aren't screwed to the rims. Been doing this for the past 6 seasons without any issues. The tubes keep the tire stiffer at launch and all the way down the track.


yep I agree with Monte, don't matter how many passes or years you have been doing it you are taking a huge risk for yourself and the car in the other lane. I would refuse to race you.

Find the spot in the rule book that states

Car must run tubes

car must have screws in rims

You goofs still doing dry hops too ?

I run a fairly light car (Altered) with 17x33 tires & have run 14x32s on a 3800lb car. I've run tubes & no tubes but NEVER did I not "pin" the tires. As someone said, it only takes one time & you'll REALLY regret it. On both cars they seemed to react better, tires lasted longer and with no tubes the 60' was better. I've always indexed the screws, as mentioned previously, so the only conclusion/ question I can come up with is : For the small time & expense, why WOULDN'T you "pin" the slicks to the rims to avoid any potential problems when there's tons of evidence it actually helps?

Then you better go thru tech with everyones car and also, you better check their drivetrain to see if there is a failure going to happen soon there too

Good lord

Know better than what ? To disagree with you ?

You really think, if NHRA thought for a 2nd after 60 years that you needed screws, they would not have that in the rule book ?

So do you inspect every car that lines up against you for EVERYTHING that MIGHT POSSIBLY GO WRONG?
I'm estatic to know that I'll never have to race you...maybe my 8 3/4 would break and send shrapnel into your lane too

here it is, if you dont think it's dangerous to have tubes in a wheel with nothing to prevent them from shearing off the valve stem somethingb is wrong with you I don't need nhra or anybody else to tell me it's dangerous. I have seen it happen, lucky the tire went down in the pits not on the track at speed.

I dont have any screws and I never have, I have been through tech over and over and they have never said anything about rim screws. Even though I marked my tires last year and seemed to turn a couple inches each run. I was told if they turned it would break the beads with no tubes? I had tubes in my old slicks and when I bought my new Hoosier Q.T. pro's at the track the Hoosier dealer said dont run tubes!! I have a 8 3/4 to!! 3800lbs
I will probly screw them for next year.

You really crack me up. I go low 8's with no tubes or screws in a 3300 lb. car. Been running it this way for 12 years. Never had an issue. I run 12.75 lbs. in my TT5 M/T.

Well after many months of not agreeing with you. This time with you. Never run a slick with tubes without screws. Valve stem is guranteed to shear off. My buddy that goes as slow as you heared off his valve stems w/o screws.

I would screw the rim too if I had tubes in
Back in the day, many people just put a hose clamp around the valve stem to keep it from being pulled thru
