These 'Super' Sports replaced the OEM Michelin Pilot Sports which still had well over half of their tread left. I am incredibly pleased with the switch. Somehow I have better steering response and really predictable on-the-limit handling, yet with definitively better comfort and much quieter road noise levels than the OEM tires. Oh, and at a much better price. I am absolutely sold on these tires - I lost nothing in the switch. Simply better everything. I can only assume this is down to improved technology and improved compounds. I wouldn't even consider another brand or model of tire when these wear out. Outstanding.
