Old Tires to take over from the new tires…. all Pirelli P-Zeros old Classic, new T-equipment. This year I ran the rear hard, very hard to say the least. Up until the rock in front of my driveway pierced through and punctured my tire. I did u-turns on which I spun out the rear, sometime w/ tractions control and sometimes without. Oh how much the electronic nannies help… and how much they limit, all in the name for safety. I will take them, but if I can…. release them, let her loose and live young!
