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.
