What is normal wear for a drag tire?
: There is no set degree of “normal” wear. If you feel you are getting to much wear, look to shorten the burnout time in the water box. Too much burnout will shorten the tread life of the tires. The softer the compound the more wear you would see given the same amount of burnout time. Most wear to the tread life of a drag tire comes from too much time in the burnout procedure.
