I'd choose a brick and mortar store with a reasonable price and good reputation and just do it. You can buy tires online for a great price but usually it's a wash when you take them anywhere for mounting and balancing. I read here on Moparts the white lettering on the TA Radials turn brown shortly after washing off the blue coating. The brown discoloration evidently does not wash away. Thats a shame because I think TA Radials look the best. Cooper makes RWL tires and some lesser known choices are, Mastercraft, Galaxy and Milestar
