I have seen there is a new tire out by bridgestone called the Potenza S03. Any thoughts on this? Anyone used these tires yet? Also, if I decide to change to those tires, should I change all 4 tires, or can I keep my S02's on the front since their tread is still good??

 

You'll probably find alot more info by using the search function on this board. The S-02 discussion has been a long going topic with owners.

The S-03's are the replacement for the S-02 Pole Positions, which are different that the OEM S02's. The OEM S-02's are "W" rated, adn have more contact pacth surface than that of the other versions of the S-02's. There are also S-02's for Porsches (Usually denoted with an "N")

S-02 Pole Positions, and their replacement, S-03's are desoigned to be better all weather performance tires. You wil lose some of the dry road handling but increase wet traction. Depending upon what you are looking for, and how you drive, you may find S03's perfect for you or, really hate them.

I am sure a search on this topic will yield you more info, but this is a summary of what I remember of the discussions.

 

if you take a look at tirerack.com (one of our site sponsors) you can do a very comprehensive comparison search on those tires vs each other, as well as others. ratings include wet and dry handling, warranty, price, and lots more. worth looking at.
