I bought all four tires at Costco in Windsor for $644.00 out the door. I live across from Detroit and the tires were only $2.00 more than Belle Tire and when you factor in the $10.00 return toll to cross the Ambassador Bridge, the exchange on the money (10 cents on the dollar) and the gas, I actually saved money. The Kumhos were not that bad, but I was going to replace them in September anyway and I saw the price and had to pull the trigger.
