We are running in a class that says "Only true radial tires allowed, Drag radials and soft compound tires not allowed." One competitor showed up on M/T E.T: Street and another on R/T Sportsmans. A debate ensued if the R/T´s would qualify as soft compound, the E.T. were definately illegal. The wisdom I have picked up on the www is that "true" radials have a treadwear of 400 and higher. The R/T´s do not give any info about its treadwear.

My Charger had a bad day; spinning the wheels almost half track. There is another race on June 19th. I plan to do better then

Thank you for your interest,
