tirerack.com. I'm in the market for tires. The sites that look the most used are tires.com. which is Discount Tire Warehouse as well as tirerack.com. Like the user feedback there. Also need to check out 1010tires.com which is a Canadian company so the exchange rate is quite good. I particularly like the user reviews at tirerack.com. I'm probably going to get the Bridgestone Pole Position's for our Volvo and then some winter tires as well. On 1010tires.com is some good information about maintaining things. Good point is that you need to rotate tires very 8,000 miles or basically every other oil change.
