When I purchased my new Infiniti Q50 it came with Bridgestone Tires reviews Run Flat Tires. When I did my winter- summer tire change, my service company (Tire World) pointed out to me that the driver's side front tire had a lemon (ha!) sized blemish on the sidewall. Odd since I had only 7K miles on it, and no tire or wheel scuffing to indicate that it had been curbed (which is what Bridgestone would say later) so I called the company who referred me to a local Firestone Dealer.
