And like I told you, I highly doubt that drag radials will pass tech inspection for auto-x.
I saw these on tirerack.com. Good price, and had 9.1 reviews for handling. They seemed to have higher reviews than other, more expensive tires with softer compounds. These Michelin Pilot Super Sports appear to have 300 treadwear, VS 220 for Perelli P Zeros.
