The Primacy is my first Michelin tire ever owned (I am 65)and the best tire I have ever owned. My OEM Bridgestone Turanza EL400's wore out in 8,500 miles. My Primacys now have 61,000 miles on them and are at 4/32 tread depth ..... treadwear indicators still not showing but I will be replacing them soon with another set of Primacys. If I drove them to the treadwear indicators, I'd probably get 70,000 miles out of them. Quiet tire with great traction and superior handling.
