Replaced the OEM Michelins. Traction, handling, and stability of the OEMs with the added bonus of being much quieter. Haven't experienced them on hot pavement yet, so I'm not sure how chirpy they will be. Bottom line: I'm very pleased with these tires. I shopped hard for a Max Performance tire that didn't create a lot of road noise due to the occasional long trips over highway I make. So road noise is important to me. Finally, like all Michelins, these Super Sports are a little pricey, but so far, very much worth it. Believe the high ratings you're seeing from everyone. CR rates them tops too.
