I purchased these tires for a road trip, 500 miles one way, and I'm very pleased with them so far. I haven't had a chance to drive in the rain yet but, the dry traction and level of road noise is very good. I've gone thru 3 sets of PS2 and 2 sets of Michelin AS. I don't drive it like I'm on the track but I do have fun on the occasional off ramp. These tires are comprable to the PS2, PS2 has better steering feel. The Sumitomo's are quiter and for the cost, it can't be beat. I will update my review after putting some more miles on them. Thanks to others who have reviewed them, I'm not dissapointed. When it comes time to change out the tires on the porsche, these will be going on them. I think these tires are an excellent street tire.
