What is the rule of thumb of when to put screws in the rims when using slicks ? what ET or power level or always? Also what if you don't would it cause problems with valve stem on the tubes tearing off ? thanks

If I use slicks I use screws-especially if you are using tubes.

Good question. 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?

OT a little, Why use tubes anymore? Not being a smartazz as usual. Just asking? as I think tubeless is safer with screw in metal valve stems.

Personally i like running tubes,,,sidewall seems stiffer,,,tires hold air longer,,,not sure what the downside to tubes are,,,other than weight,,,,

I personally do not screw my rims since I stopped using tubes. Is there any reason anymore to screw the tires on unless you're running tubes?
Master, again and still

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

There is no answer to this question. Too many variables. Monitor them. When you see them start to slip on the wheel, thats the time to screwem.

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.
