Pirelli Pzero Rosso vs. Bridgestone SO3 PP's: which will get better mileage?
It's almost new tire time and I'm wondering which way to go. I'm VERY happy with the performance of my current set of Rosso's, but they only gave me about a year of service so I'm wondering if the SO3's are going to be a longer-lasting tire. Thanks in advance...

The Bridgestone S-03s have a treadware rating of 220. The Rossos have a rating of 240. That means
that the rossos will last longer by a percent of 240/220, or 1.1 times longer than the Bridgestones (i.e., 10% longer). I have put around 5k miles on my S-03s, and they still look new, except for some scrubbing on the outer edge from an auto cross clinic at the Quattro Challenge. I'm expecting to get 20 to 30k miles out of them. In fact, my Dunlop SP 8000s that were on my A4 before this went 30k miles, and have a treadware rating of 200.

more or less true, but comparing treadwear ratings of different manufacturers should be taken with..
a grain of salt, as each company sets their own standards when defining a base treadwear of 100.
Yes, they're all governed by NHTSA guidelines, but there's a certain level of "play" in there.
Hence, comparing treadwear ratings among different tires of the same manufacturer makes sense, but among different manufacturers - not.

there is no industry standard for treadwear..so you have to rely on manufacturers honesty...
but given those two tires, iwould agree that the pirellis will last marginally long than the S03's. But given the bridgestones better wet performance, i'd give up mileage for performance anyday.
got 8k on my Pilots.

My Rossos wore like CRAP!
First off, the Rossos seemed to have to be sliding when generating good grip. That leads to a feeling of sloppy handling and probably wears off the tread while sliding in the process.
Secondly, they wore unevenly. All 4 tires had the wear bars showing in the middle of the tread, with 50% more tread on the edges. This was in an 18" size, 225/40-18 on my S4 at 38f/36r pressure (Audi recommends 36f/34r on 225/45-17's) and none of my other tires have worn this way. I replaced them at about 13,000 miles, and that included mostly freeway driving plus a 3,200 mile road trip. Friends reported this seemed to be a Pirelli feature.
Third, even if I wouldn't have worn out the center tread, those tires wouldn't have gone for more than 17,000 miles, and given how I was driving on them and a 240 wear rating, they should have gone 20,000-22,000 miles based on my experiences with AVS Sports and Michelin Pilot Sports.
