It seems that restricting tyres on some treadwear number may well be a real can of worms Tony. We are still waiting to hear back from Dunlop regarding a treadwear number for the Direzzas (probably one the most popular DoT/road legal race tyres in NZ) or even if such a number/ rating exists. It seems that this number is primarily a US market initiative and may not be available for tyres not used in that market and at best seems to be somewhat arbitary.Originally Posted by RacerT
Given that there were a number of competitors using the Hankook at last year's Festival and Ray appears happy to allow them in his series maybe that ship has already sailed. I am finding the combination of purchase price, performance and a wear rate which seems at least no worse than other DoT tyres to be a fairly compulsive argument.
