Screws in side wall for slicks

Dual bead locks for radials. You cannot screw a radial.. But if you don't run tubes with 20 lbs and up they stay in place on a mild 10 second car

Screw both side for slicks with tubes .

You can glue either but wait until you go to break the bead to change them. With the soft side wall it is nearly impossible depending on the glue.
