Discount Tire - purchased Michelin Pilot A/S 3, run flat. Since my Vette is a daily driver I went for the A/S type tire. Plus no more tire hop when cold!When you replaced the tires on your C7 vette ,where did you go to get them done, a dealer , independent garage , franchise like tire rack? I understand a certain machine is needed to change these tires due to the type of rims on the car. Any bad experiences ?
