I don't like using tubes in any of my drag race tires,no screws either Your committed so trying rotating the tires side to side and watch the movement. I inflate my new tires to between 25 and 30 lbs to seat them on the rims and let them sit overnight before using them at the lower pressures needed for racing They still move some, both the radials and bias plys The tire moving with the tube is a big No No your taking a chance on ripping the stem out of the tube
