My initial set after my RSA's were the Michelin's Pilot Sport A/S Plus (Ultra High Performance All-Season) Paid around ~$1300 3 years ago when they first came out and were rated #1 for ultra high all season performance, currently rated #4 by Tire Rack.

They lasted about 3 years and almost 35K miles.
I just bought a second set of tires, the Bridgestone Pontenzza S-04 Pole Position (Max Performance Summer) for $1132 when it was all said and done. This tire is rated #2, right behind Michelin's Pilot Super Sport which is currently rated #1 for Max Performance Summer.

By the way, both tires performed wonderfully when new. The S-04 PP give a softer ride, also my no1 criteria was driving in the rain... since it rains so much down here. all the other parameters matters, but not as much as wet handling..
Now keep in mind I have been a Michelin tire guy ALL of my life, I must of bought 10 or more sets on all of my cars over the years. However, I purchased 2 sets of tires (a set for my Sky, and 2nd set for my daughters G6 GT, a different tire model, don't recall that model number and apparently has been discontinued), from them in both cases (to my astonishment) both sets sets showed sign of what I describe as "brittleness"... Cracking, and hair line cracks developing on the tires. In my first set above, it was pretty bad after 3 years, so much so that small chunks were being broken off, and it picked up a tack which punctured it, that is when I decided to replace them with the Brigestones since my wife pilots my Sky on her daily commutes.. tire safety is paramount with me. Also the place I bought my current set, that tire guy stated the the michelins have 'developed' this phenomena lately on this cracking business. Therefore I decided to go a different way. Hopefully all of those people currently buying the new Michelins Pilot Super Sports will report back yearly to see if this "brittleness" has been resolved before I buy another set of Michelins

. Just thought i would share that information.. To many tire options to not check everything out.. good luck on your selection..:thumbs:
