Well, I just placed my order with Tires.com for a set of Yoko Geolandar HTS G052 in P255/55R18. I was able to get the 4 tires with a tire warranty for LESS than TireRack's price for just 4 tires shipped.

Honestly, I've been a customer of TireRack for about 7 years and have purchased many sets of tires through them. I was truly torn between the two retailers, but the price difference was too large to ignore. It was TireRacks surveys that helped me make my decision though - Tires.com quality and quantity of surveys/responses are not nearly as good.

Once I get the tires mounted and balanced and a proper 4WA done, I'll let you all know how the tires are.
