Oh jeez just cut the BS. There's nothing wrong with a short burnout to clean the tires. I don't care what brand the tires are or whether they are bias ply tires or drag radials or even street tires. Then find out what tire pressure works for you. With YOUR tires, YOUR suspension, on the track YOU run on. If the tires are not contacting all the way across, an adjustment is needed. Pay attention to what's going on and make adjustments as needed. There's no reason that you need a specific air pressure no matter what. You have to adjust to the results.
