Hi all, I am running a bike in the M750PG class this year, and I have a question regarding my tires; The class record is 137.8MPH, requiring tires in the class to have a "V" rating. The tires I have are Avon AM23 (rear) and Avon AM22 (front) tubeless tires. I will be running them tubed on (spoked) Excel rims. On the sidewall of the tire it states: "If running with tube max speed 210KPH (130.9MPH)" In the rulebook, it states that shaving a tire will bump the tire "up" one speed class. If I shave these tires, will they be "within regulation" to run in my speed class?
