I can feel the difference between the PSS and the RE050As. The PSS make the car feel slightly quicker off the line and my braking feels slightly better as well. The RE050as did feel like they may have had slightly better steering response though

Just got a set too! For the people who have purchased this tire size combo, has anyone noticed when going over a "dip" over 35mph, the sound of tire rubbing in the front?

^I don't have them but I'd be surprised unless you are lowered, have spacers, or aftermarket wheels. Even slightly lowered, I never hit the fender liner with the 245/35 PSS on stock wheels.

Lou obviously you are the most vocal proponent of the Bridgestones, so this is really directed at you.

I have been waffling between the 235/40-265/35 and 245/35-275/30 combos in a Michelin PSS, on the OEM late wheels. Car will be lowered 1" in the front from stock ride height.

I like the idea of the 285/30 in the rear both for the extra 10mm in width, as well as the extra .200 or so in height (over the 275) to match the front tire height (would obviously run a 245/35).

My only concern is the weight of the Bridgestones as opposed to the Michelins. Thoughts?

Sure...rotating mass is not something you want to add to a car but come on now...seriously? tire weight? Are you trying to set a time attack record or something?

Sure, I thought about weight when I made my decision, but the other criteria you mentioned outweighed that in my mind. The PSS is a darn good tire, but as we all know, it doesn't come in the correct 285/30/19 size. So I read the reviews and took my chances. I did try the Continental DW first, and those, IMHO, are a crap tire. But I'm very happy with the way things turned out with the S-04.

Hahaha! Negative, but I always compare tire weights across brands when contemplating a tire to put on one of my vehicles that I drive hard. I have vehicles with everything from 205/55/16 to 38x15.50x18, and know that a few extra pounds of unsprung weight can make a difference (however minor it may be).

Any other feed back out there on the SO4's ? Tire rack has them for $800 plus shipping while the PSS are $1018 plus shipping. No tracking here (well maybe once) but more so an everyday car.

The Potenza S-04 is an excellent tire that I recommend to customers very often. I sold some to my best friend for use on his Chrysler Crossfire that sees some track use and daily driving during the summer only. When they came out, they were the #1 tire in the Max Performance Summer category, but they were surpassed by the PSS when it was released. The PSS has better grip in the wet and dry, it is quieter and rides better, and it lasts longer. I sell the S-04 when the PSS isn't available in the appropriate sizes or if the PSS is out of the customer's budget. Basically, the S-04 is great, but it's definitely the #2 tire in the category. I hope this helps.
