+2 for Tire Rack as well.
I've used them many times and the tires are always in perfect shape. Best prices and by far the best selection.
My local tire places are expensive, except for some that have brands I've never heard of.
Just stay away from the stock Goodyear tires. Summitomo's will do OK, but treadwear is very low. No need to buy the most expensive tires, cause there are plenty other that have been mentioned that have better than average traction in rain/dry AND also have a decent treadwear rating.
