For 20 inch wheels the best quote for a set of tires I've got is $684. That's for the Hankook's which are decent tires for a good price. A lot of members run Hankook's on this forum from what I've seen. $684 is just for tires only so guess around another $100 after mount and balancing.

 

Just ordered Michelin A/S 3s. Car came with the standard Bridgestone Potenza RFTs when I purchased the car. The car came with a spare so I was told I could go either way. These came highly recommended by a friend and all reviews seem really positive..even though its a All Season. I guess we will see. They are rated for 45K.

I will have to Bridgestone's RFTs for sale. They had a 6 out of 11 on the meter.

 

I really like Yokohama S.Drive! I got a set of 20s as well and planing on stretching them a lil so s.drives are good for that and don't bubble as easily as the V12s.
