Hi Pish, Welcome to PriusChat. There are a lot of threads here about tires for the Prius. Use the Search (Advanced Search) function to search titles only with the word "Tire" or "Tires" in it. In any event, the best thread on the subject is nyprius' "Tire Upgrade ..." This thread is long, but you should at least read nyprius' excellent initial post: http://priuschat.com/forums/prius-modifications/20573-tire-upgrade.html Good luck.
