I had a pair of slicks that where really bad, it would feel like it was hopping off the ground around a thousand feet in high gear I balance every pair now on a bubble balancer No screws or tubes, I do use dishwasher soap and water to mount them and then inflate to 25+ lbs to help seat the beads, I check the circumferences with a seamtress tape and inflate them to get them both within 1/4 inch of each other at race pressures I do mark the wheel and tires and watch for rotation(slipping)I swap them to the other side if the tires are moving very much, as already said once they move and get swapped to the other side they seem to stop moving after that
