tire rack is a door-to-door orgasm of tire and wheel greatness. used them many times on my VWs and my S4. tires came mounted & balanced on the wheels, all shipped nice & bubble packy, from the nice UPS man.
jack the car up, throw 'em on, and you're rollin' in style in no time. if TR has a better price, you can't lose.
The only way you can lose is to pay more than is necessary. unless, that is, you like doing that kind of thing.
