I'm about to change wheels and tires. My car is set up for cornering, so I drive fast in canyons and hope to run an occasional road course track day or time attack. In 15" the only speed rating in the sizes I like is "S". Has anyone run these as hard as I will be with these S-rated Goodrich T/A or Firestone Indy 500??? I know that stepping up to 16" size opens up a whole lot of possibilities, but I thought I'd ask for help first. Any opinions??? Thanks!
