Potenza S-04 vs Pilot Super Sport on CS7's (decision factors)?

I have narrowed my choice to:
- Bridgestone Potenza S-04 Pole Position
- Michelin Pilot Super Sport
* Both tires are well respected/highly rated
* Comfort is acceptable
* Wet and dry rating are high
* Both are quiet tires, compared to the competition (through the life of the tire)
* Both have stiffer sidewalls
* The PSS's are a lighter tire (better unsprung weight)

Setup and driving:
- KW SC C/O's with a 5/8 to 1" drop (on order/not installed)
- Alufelgen CS7
- FR 225/40/18 RR 255/35/18
- Daily driver + spirited driving, no track use
- Currently on Dunlop SP Sport 01 DSST RFT's
- Tires will be used all year (SOCAL weather)

My key decision factors are:
1. Rubbing and fitment
- I have Alufelgen CS7's (18") and read about rubbing issues on the PSS's
- The S-04 tread width seem to be have slightly narrower tread width (.3 narrower on the rear tire)
* That might be a good thing (rounder sidewall)
* I am willing to do a fender roll, if necessary

2. Cornering response
Since I am coming off of RFT's and who knows if I will ever get the M3 control arm kit, I removed other tire choices due to the softer sidewalls and poor cornering response
- The S-04's seem to get equal or slightly better overall rating cornering response compared to PSS's

3. Tread wear
- Hopefully get decent miles out of the tire
- The PSS's have a better UTQG rating (300 vs 280), but who know if this really means anything...
- The S-04 claims superior tread wear toward negative camber
* http://www.tirerack.com/tires/tires....+Pole+Position


Finally, My questions are:
- Has anyone ran both the S-04's and PSS's? Any comments/comparisons?
- Anyone with Alufelgen CS7's running S-04's? Any fitment issues?
- Did you get the expected life out of the S-04's/PSS's?
- Did the extra weight of the S-04's seem noticable?
- Any uneven wear due to negative camber and lowering?
- Just go with the PSS's and know that you will be able to fix the rubbing issues!


Any help would be amazing... Thank you!

I was in yor same position, but I couldnt find the Pole Positions here in Mexico, so I went ahead with the PSS.

FWIW, I was pretty concerned about all the reviews about the "loss in sharpness" when ditching the RFT, but at least in my opinion its a little overexagerated by some. I got the tires inflated with nitrogen at 40 psi and I could only feel a LITTLE diference in sharpness the first day, afer that, you dont even notice.

I think it doesnt really affect the performance of the car at all, only the way you feel it if you're extremely picky ann like complaining about minor things.

In conclussion, PSS are relly good tires, I normally dont believe in the internet reviews as they all talk wonders abut all products, but these tires really perform. Pus they are supposed to last longer than tires with less threadwear and same or less grip.

Thanks Boosted1...

Anyone else have real world experience with the S-04's? There isn't a full review that I could find on this forum for the E82.

I like that the S-04 tire is slightly rounder due the clearance. If I wasn't so concerned about a soft sidewall and cornering, the Conti DW would be my choice due to cost and life of the tire. If noise wasn't a problem, there are other comparable options.

Any other comments or suggestions?

Thanks!

Well went with the Potenza S-04's. $100 less than the PSS's at Americas Tire/Discount Tire and they bought my RFT's for $200.

Should have them on in a week or so... I'll post a review once I have some impressions and a few hundred miles on the tires.

I have a set of PSS and they are GREAT! Excellent grip, great wet performance and great tread life. I have run them hard and the tread wear is surprisingly minimal. The tires really smooth out the ride compared to my runflats...no more jarring BANGS on bumps.

I have PSS run flats, and although I have no other frame of reference since these came on the car, they perform a lot better than what I've read. It almost seems like they are too sticky for the suspension. I get significant body roll on off-camber turns and the dreaded rubber band effect but the tires stick and stick. When they do start to go it's a progressive loss of grip even without dsc on.

I also have not experienced any rubbing with 235/40/18 and 265/35/18 and Dinan stage 1 suspension.

Michelin Pilot Super Sport do not provide any run flat capability in the event of a tyre...


how do you have PSS RFT?

I almost responded that I was positive, but I had to go check. They are PSS, but don't appear to be rft's. The dealership swapped the rims and tires, but told me they were run flats. Silly me I believed what they said. I'm guessing it was an honest mistake since they are an upgrade over stock.

All other input still stands though, they are really quality tires. My only other frame of reference with z rated tires are pirelli, kumho, and BFG g force on a 99 Contour SVT. These are hands down better in all aspects ride, performance, and noise.

Thanks for catching that I'd be running around with a flat tire wondering what the hell was going on!

I am really impressed with the S-04's. One of my major concerns was missing the crisp turn in on the RFT's. Honestly, the difference is so minimal I think going with the S-04's with a stiffer sidewall was the way to go.

- Cornering response is almost comparable to my Dunlop SP Sport RFT's
- The ride is forgiving over street imperfections, no more jolts!
- Grip is impressive, but I am sure it will only get better (only 150 miles so far)
- No clearance issues with the CS7's and 255's with a 1" drop (fender rolled just in case)

So far, no regrets. We will see about tread wear and post break in results.

Precisely why i would avoid the PSS s because of the rub issues, whereas the S-04 is not as wide as the PSS, so it wont rub, i hope.

- Side pic attached
- No rubbing with a 1" drop, over bumps or passengers (front/rear seats), but note that I rolled my fenders just in case
- Wet traction is great
- Bridgestone was offering a 30 day money back guarantee, might want to check and see if this is still offered
- Yes, the Wheels are Alufelgen CS7
http://www.alufelgenwheels.com/wheels_type.php?type=cs7

I am still very impressed with these tires. If the tread wear holds up, I will definately be purchasing them again!

Very nice! something to consider. I ordered the tires based on your experience. Thanks!
Rims are a toss between the VMR710s or the 264's OEM. Will shall see.
