Also what if you don't would it cause problems with valve stem on the tubes tearing off ? thanks 1969 Dodge Charger 1969 Dodge Superbee

I started screwing mine together when I seen the tire move on the rims. I marked both and watched them close. Mine started moving in the low 13's and MPH was 110. My car weighs 3800lbs too.

Im new to this racing in a strait line and was wondering the same thing. What if your not running tubes? Size of tire and pressure comes into play?

Not being a smartazz as usual. Just asking? as I think tubeless is safer with screw in metal valve stems.

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. 6442263-atcowheelieresize.jpg (69 downloads)

My tires are stiff sidewall , and honestly they hardly leak air I always ran tubes , and screws and bought into the wives tales myself . Needed ? Maybe ..but so far so good here !!

They had bead locks on it in Tulsa Meh' I don't know , I find it hard to believe that 5-6 little #10 screws with the tapered end sticking into the tire bead maybe and 1/8 of an inch matters in anyway But, it is up to those to decide for themselves My tires have never moved any, none, zero,zip,zilch,nada But they rims are 15 inches wide and the tires are 16 inches wide so that may matter too

Also what if you don't would it cause problems with valve stem on the tubes tearing off ? thanks We talked about putting screws in wheels at the Dave Morgan Chassis Seminar that I attended. There are a lot of factors to consider that get over looked. Things I would have never thought of. For starters, You want to "Index" your screws. Basically, where ever you put a screw on the front side of the wheel, make sure you put the screw on the back of the wheel directly across from the screw on the front of the wheel. If the screws are staggered , this will cause the car to "wonder". Mis-aligned (staggered) screws tend to want to "twist" the tire, as the tire is being pulled from those points at where it is screwed to the rim. Here is the best picture I could find in my library. SORRY it isn't a Mopar. You can see that the wrinkle is pulling from where the screw is on the wheel. Second, how many screws do you put in the wheel? That depends on how big or small you want the "paddle" of the tire to be. Watch some of the high horsepower cars, and the tracks they make out of the whole. you can see the tire is "paddling" the ground. If the screws are further apart, the "paddle" is bigger, the closer the screws are, the smaller the paddle it. for example.... 5 screws around the diameter of the wheel will make for large paddles, but fewer paddles (4 paddles) 10 screws around the diameter of the wheel will make for smaller paddles, but more paddles (9 paddles) What is the right amount of screws for a car? That I don't know. I personally haven't run screws. My tires seem to hook up just fine with out them. -Kenny

No tubes EVER for me and they leak very little when it sits for a couple of weeks. Next step............bead locks; Can`t imagine the high hp 6-second cars NOT running screws or locks.

ProSport I Live Here Joined: Jan 2003 Posts: 17,918 Akron, Ohio	I quit running tubes years ago just because I had 2 valve stems rip off the tube and quickly lose air, could be dangerous. I think this happened because the hole in the wheel didn't properly line up with the valve stem on the tube. I use Dawn dish soap and no tubes, and I use 8 screws on each side of the wheels. I saw a Mustang wreck many years ago from breaking a bead. I've heard that running 16 screws on each side of each wheel will help stiffen the sidewall. Also, I recently read that the screw should thread into the wheel, I didn't know that, the holes in my wheels have always been bigger than the screws so the screws just thread into the tire. 340Rick and Bobsprofab turned me onto a stainless screw that has a nice rounded head and uses a square drive bit, they look clean and can even be polished. 1970 Challenger, all aluminum 528 Hemi, HDK suspension, Tremec 5 speed manual

Is there any reason anymore to screw the tires on unless you're running tubes? If you have enough power and bite you can knock a bead out and the tire will go flat instantly. The lower the tire pressure the more likely this could happen-especially if you are "driving" the car. That's why faster NHRA cars are required to use beadlock wheels.

Running 16 screws each side probably acts like a stiffer sidewall because you are anchoring the tire to the wheel more often, and closer together. I have notices some of the higher powered small tire cars are running more screws. That "Square bit" screw you speak of is a Canadian invention It is called a "Robertson" Head. I really like them, much easier to use with out striping the head of the screw or the end of your bit. -Kenny

I prefer to screw them on. If the tubes are installed properly you won't rip out the stems. Use plenty of tire talc inside a dry clean slick, that means all the soap residue must be flushed out or your tube will stick and rip. it's ok to butt heads, just don't do it with a butthead

If the tire ever happens to slip on the wheel, it will likely rip the stem out of the tube and you will be in for a rough ride, straight into the wall. I understand you have done it for 6 years. But all it takes is once. Personally, I think people are nuts, not to anchor the tire to the rim in some way, but thats just me. Last year at an ADRL race, I saw a driver get after an XTF car too hard in the water and knocked both rear tires off the beads. Thats how fast it can happen Monte Last edited by Monte_Smith; 01/28/11 02:18 AM.

I did mark the tire to the stem and mine moved all the time... thing was I never knew if it went a few inches or a few turns... then I switched over to running tubes and screws... this currant set up has yielded my best 60ft with a 1.19 and I think its the stiffer side wall....also I get more runs out of a set of tires... I never get rid of the tires due to being worn out (tread surface) but the side walls giving out and when they start going I see the 60 ft going away. So for me its a better set up all around with tubes and screws..... my opinion is if you have a big tire with low pressure you COULD be asking for problems

I agree, I have a buddy runnin 8.60's in a 2800# car and when he spent $450 a piece on new rims he sure wasn't gonna drill hole in them. We marked the wheel/rim and it moved about 1/2" after the first pass then never again.

If the tire ever happens to slip on the wheel, it will likely rip the stem out of the tube and you will be in for a rough ride, straight into the wall. I understand you have done it for 6 years. But all it takes is once. Personally, I think people are nuts, not to anchor the tire to the rim in some way, but thats just me. Last year at an ADRL race, I saw a driver get after an XTF car too hard in the water and knocked both rear tires off the beads. Thats how fast it can happen Monte I really don't know what these guys are thinking. Maybe they just haven't seen this stuff happen themselves.

Also what if you don't would it cause problems with valve stem on the tubes tearing off ? thanks We talked about putting screws in wheels at the Dave Morgan Chassis Seminar that I attended. There are a lot of factors to consider that get over looked. Things I would have never thought of. For starters, You want to "Index" your screws. Basically, where ever you put a screw on the front side of the wheel, make sure you put the screw on the back of the wheel directly across from the screw on the front of the wheel. If the screws are staggered , this will cause the car to "wonder". Mis-aligned (staggered) screws tend to want to "twist" the tire, as the tire is being pulled from those points at where it is screwed to the rim. Here is the best picture I could find in my library. SORRY it isn't a Mopar. You can see that the wrinkle is pulling from where the screw is on the wheel. Second, how many screws do you put in the wheel? That depends on how big or small you want the "paddle" of the tire to be. Watch some of the high horsepower cars, and the tracks they make out of the whole. you can see the tire is "paddling" the ground. If the screws are further apart, the "paddle" is bigger, the closer the screws are, the smaller the paddle it. for example.... 5 screws around the diameter of the wheel will make for large paddles, but fewer paddles (4 paddles) 10 screws around the diameter of the wheel will make for smaller paddles, but more paddles (9 paddles) What is the right amount of screws for a car? That I don't know. I personally haven't run screws. My tires seem to hook up just fine with out them. -Kenny Good info. Thanks! Fastest 300

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?

I have seen it happen, lucky the tire went down in the pits not on the track at speed.

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.

I have run slicks with out screws but never with tubes in them. although I do think you get a better result with screws and safer to boot.dosn't matter how fast people have gone with out them. take a look at how many people have posted problems with out them. it only takes opnce to have a bad day.

I run tubes now for the extra sidewall strength, it does improve the 60ft's, at least on my car. If I'd been running tubes back then I have no doubt I would have torn the valve out of the tube. IMHO for the little time and money it costs it's worth doing for the extra insurance, I've also yet to see a car run slower after screwing the tyre to the rim.

If it might be beneficial and it can't hurt and it doesn't cost anything, I just do it, but that's me. I know my 60' improved a bit and became more consistent when I went to 16 screws per side. If the results don't match the theory, change the theory.

Not sure what your trying to get at here... No your situation won't compare with this set up BECAUSE your not running any screws. Screws serve the purpose of holding the tire where it is, but they also serve the purpose of controlling the "paddle" of the tire.

Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.
