I bought new wheels so I posted a question about screwing slicks and balancing over on the bullet and this is what most do. If mounting slicks on mew wheels WITH-OUT tubes guys scuff and clean the wheels lip, soap the inside of the tire carefully (side walls for leaks) keeping the slicks lip clean and dry, mount the slick on the wheel, spray or brush "High Tac" gasket sealer on the slicks lip, blow up slick to 20 pounds pressure over night, bubble balance and mark slick and wheel to see if it moves or I should say how much it moves. Most of the guys said it will move some and stop but the don't re-balance. I didn't really want to drill my new wheels and they said if you do it this way you don't have to drill them.
