Bridgestone Potenza S-04 Pole Position
Follow-Up Review: 10,000 miles on tires

Not sure if I correctly update the category ratings....however-- <br><br>To be a good Reviewer is to be fair and realistic, right? <br><br>I am updating the reivew to include new found information. After noticing extreme inner edge wear on just one tire realized that the front wheel bearings were worn and loose. New ones were installed. The car came back to life. The steering was vastly improved. It was fun to drive again. <br><br>The S04 tires, naturally, were also much better. Steering thru corners and general tracking was finally acceptable. Yes, acceptable like when you were a kid and received a 'C' grade. Got the job done, but left a fair bit on the table. <br><br>The massive inner tire wear stabilized. However I think these tires too sensitive to toe-in and camber. This car does not have extreme suspension specs. Which makes me think the tire is too sensitive. (Granted a modern Audi is very nose heavy and generally hard on front tires, depsite AWD.) <br><br>For example the current Michelin Pilot AS/3's are wearing perfectly. No abnormalities. <br><br>Overall I may have been a bit harsh on B-stone. However the ride quality is commensurately Harsh, too. In a couple months I'll put the summer tires back on and see if I need to update this again. <br><br>Thanks everyone.
Initial Review: 7,500 miles on tires

Purchased for all season wet use. Very easy break-in with multiple rebalances as tires settled in. Tires hold balancing quite well, however.
Biggest complaint is the poor ride quality- tried various tire pressures from 35PSI to 43PSI (OE spec is 36psi to 49PSI). Went with 35 series instead of 30's but can only surmise it helped any. Wanted the higher load index (100) to hopefully prevent flat spotting- no such luck. Takes a couple miles to warm up. The RE962's were even worse (different size).
The Audi is heavy and powerful (4260lbs; 515hp/500tq) and generally naws thru tires rather quickly, especially on the front. The 275 width on 9.5 wheels doesn't seem to have helped much, if at all, since the circumfrential grooves just get bigger, reducing the foot print. Had Michelin Pilot's (old) that bubbled, so got the B-stones. Immediately noticed the stearing vagueness, but hoped once the tires wore down a bit, steering response would return. No such luck. Alignment is perfect, done at a european race shop.
The dry limit seems a bit low to me, even when setting the car up long as possible to load the tires. Transient response is numb and a bit mushy (even at higher PSI), but are consisently predictable, at least it's safe.
These tires are rated 2nd on TR, but would say it's a d-i-s-t-a-n-t 2nd place. Overall, I should have anted up for the Michelins, or Conti's if I wanted to save. Friend of mine has the same car with the new Michelin Pilot Sports-- loves them.
-----Even called B-stone, but there's no tread warranty and customer service was impersonal with people seemingly flipping pages to figure out the answer. I'm a serious car guy and expect and hope someone on the other end can hold a reasonable technical dialogue and know basic info off the cuff. Think I'd rather deal with the French for serious performance tires. The S-04's are a good choice for someone that has low-ish high performance aspirations. 3rd and last set of B-stones....
