4100 lb. car. Hoosier radials. No screws, no problems.

Thanks for all the good advice! I'll try it with no screws, but with reference marks and check periodically, to see if I'm getting any movement.

I appreciate the help, everybody!!!

I have seen numerous sets of radial tires move (slip) on the wheel, from stockers to heads up 7 sec drag radial cars. I have also seen cases where the tire slippage is uneven. In other words the distance between the "marks" of the inside and outside of the tire differ by 1/8" to 1/4". When this happens, it can effect the dynamics of how the sidewalls react and cause some quarky handling issues that could easily be overlooked. I spoke with a gentleman several months back who had a similar problem with his beadlock wheels. Come to find out, the tire had slipped on one side, the sidewalls were now in a "bind", reacting differently instead of in unison with each other and this was causing the car to steer/move around early in the run.
Additionally, in my opinion, even if the tire slips evenly on each side, I don't want that variation to affect my cars performance. If the tire is slipping on the wheel, there is ET lost, or who knows even gained if the slip dampened the hit, helping prevent blowing the tire away???? Regardless, it is just another variable that we can control, so control it. Then it is just one less thing you have to wonder about.

And yes, for those of you who know me, I am biased. I have designed a tire screw (two different lengths)and stainless steel inserts (4 different lengths) so I don't have to resort to using the same sheet metal screw in a high dollar set of wagon wheels that I have holding the sheet metal up on my pole barn.

Everyone has their own opinion and way of doing things and that is what makes the world go around. So stick with what is working for you. I just had to throw in my 2 cents. Take care guys.

Chris,

You raise some interesting questions in what is a deceptively complicated issue. Looks cut-and-dried on the outside, but in reality, can have some interesting twists and turns, such as the slip on one side, but not the other, sidewall issue.

I'm gonna have to think about this one for awhile..
Thanks for you input!!!

I sandblast the bead area of the wheel to minimize slippage.
