I'm just curious as to when beadlocks are required. Also is there a recommendation on hp or tq level that a person should use them? Thanks

This would be for a drag slick. Nhra track.

I would think beadlocks would become a viable option at the 1300-1500 h.p. range. Most cars (actual door cars) woudnt have the power to necessitate it. If your spinning a tire on a rim, you can always use screws to help.

I would think unless your appraoching pro stock/ pro mod type hp, then you should be good to go with a conventional drag racing setup.

Best of luck

It's debated whether or not screwing a drag radial is 'safe'

Usually needed when you are stretching radials onto a wider wheel. For example a 275 on a 11-12" wide wheel.

I believe NHRA requires them at any speed over 210mph. Or you can run liners, but that would be for a bigger slick. If you are talking about drag radials, or outlaw 10.5, then I agree with the above statement about stretching them on wider wheels.

It's a debatable thing. I know an outlaw drag radial racer going 4.40s in the 1/8 on non beadlock non tire screwed wheels (they glue them to the rim I believe). It can make life easier on the stretching and changing of tires though...

I'm looking more for a bigger tire 33.5x17x16 slick. i'm guessing around 1,300 and 2,700lb race weight.

At that size and likely psi you'd be running, beadlocks probably wouldn't hurt.

That doesn't mean anything if you don't know the wheel width. 315's are a little more forgiving than a stretched 275. We glued the 315s on a 12" wheel and were fine, then went to the 12" 275 combo and it as trying to pull the bead off the wheel.

when you want to spend 2k on them. prostock cars ran screws for many years and had no problems

Which is why I said it's a debatable thing! You can't just blindly say "If you run 10s on slicks you must screw your rims" because it doesn't apply to every case. Once he mentioned the horsepower level and slicks size, did you see my answer change?

You are nearing the need for them. As someone else stated, prostock ran rim screws up until 12-15 years ago, but they are several hundred pounds lighter than you. My dragster has 33.5x16x15 slicks on 15x15 wheels with rim screws. It only weighs around 1600lbs tho. Regardless, NHRA requires them at 210ish mph so I have to stay under that until I can afford the beadlocks. You might look into liners like the tafc guys run. I think the will work with a regular wheel, but you would want wheels that haven't been drilled for screws. The liners use a second valve stem and act like a short inner tube that applies pressure against the beads from the inside. Then you still adjust your tire pressure accordingly and retain some sidewall flex.

Single beadlocks can be $550 for 2 wheels. I just did it for peice of mind since I hate rim screws and don't feel like peeling off glue.

Who did yours and do you have pics?

Grease pencil, mark rim and tire. if the marks move after a run, lockers required

deion82

Well I contact nhra and as far as rules 6.50 or quicker and 210 mph or faster. So I just went with a 15.1 sfi weld 2.0 wheel. Save me a chunk of money for other items. Haha

deion82

I should mention unless its a prostock or pro modified. Then beadlocks are required no matter what you run.

I've spun tires on weak 1.40 60's. Screws can work but don't like them. Since I'm trying to plant 1000rwhp at lauch,I won't have to worry with a beadlock.

Rim screws were run forever on Prostock wheels with sub 1.00 60's Just an FYI.
