    Bridgestone S-04's...and our rear wheels are only 9.5" wide, seriously?

    I was starting to look into tires. Having had Pilot Super Sports on the car I sold last summer to get my CTS-V, I fully intended to get those awesome tires again. I'm aware of the sizing issue, but figured I would just upsize by 10mm, and get 265/40-19 front and 295/35-19 rear. That was until I realized we sedan owners only had a mere 9.5" width on those rear tires. Seriously, Cadillac??? 285's on 9.5" rims??? The 295 PSS is rated for a 10-11.5" wide rim. I'm sure I could get away with being a half inch too narrow, but wasn't planning to do it. Any good deals on 10" wide matching (i.e., matching the sedan style) rear wheels from the coupe? For cheap, I'd get those, but was not looking forward to spending real money to do that. Does the offset work just fine moving those to the sedan?

    Then I looked for alternatives in our stock size of 285/35-19 rear and saw Bridgestone S-04's. I had S-03's once and swore them off. I found my old "why I swore them off" review from another forum from years ago. See below:

    #1: The sidewalls are like rocks. They have the hardest sidewalls I've ever driven on BY FAR. This leads to horrible ride quality over any sort of pavement imperfections.
    #2: Short treadlife. I only got 11k out of them. I would expect 15-16k out of a set of tires the way I drive.
    #3: Squirmy/unreassuring in high speed corners. They just don't "feel" confidence-inspiring in high speed corners. I think a lot of this is due to their rigidity. They're just not compliant enough to flex and maintain grip and begin sliding controllably. This trade-off makes them feel really good in slow 20mph corners though.
    #4: The tramlining is just ridiculous -- it's a struggle whenever there is the slightest groove in the pavement. The car is barely even controllable under heavy braking if there is a groove in the pavement.
    #5: They're heavy. S-03's are 3-5 pounds heavier per tire than many of their competitors.
    I think there are other reasons that I've forgotten as well.

    Now, I've read the test review on
    tire rack comparing them to the Pilot Super Sport and don't know how much improvement has been made on the above concerns, but I don't know that there has been any. I loved the Pilot Super Sports though. Who has an impression of the S-04's? If you can specifically address the types of things I pointed out above, that would be appreciated. This is a luxury car after all, albeit one that belongs on a race track in its spare time.

    Putting 295/35/19 on a 9.5 wheel is hardly noticeable an will make no difference how they perform just a little more bulge if you can even notice .the bridgstone s-04 is not as sticky as the Michelin . But is a decent tire I know there over 150 bucks cheeper . I don't know how long they will last on the street I only ran them on the track .

    I would go for Super Sports. As for a 9.5" wide wheel, that's appropriate for a 285 tire. Us V1 guys were stuck with non staggered 8.5" wide wheels and 245 tires.
