After coming from Michelin Pilot Super Sports in 255-45-20's on my 2012 Chrysler 300 SRT8, these Pilot Sport AS-3 255-45-20's are NOT even close! The ride noise is 65 to 75% louder than the Super Sports. They sound like a drum pounding on every tar strip/expansion joint in the highway. They sing like crazy on concrete and feel like you are riding on bricks not tires! Straight line tracking is acceptable, but hook up under heavier acceleration is an effort in futility! I have been a Michelin fan for many years, but these Pilot Sports AS-3 are a huge failure for Michelin! Purchased these tires on 05-05-2014 and I will send them back here shortly under their 30 Day Promise Plan. Bottom line is: Old School is the BEST School! Summer tires ONLY in the SUMMER! Winter tires ONLY in the WINTER! All season tires are NO tires at all!
