So I'm curious if other owners experience what I just did on these tires.
Overall, I love the PS A/S 3's. They have great ride, feel and control.
Problem is, I only got 11,000 miles on the rears as the center treads wore down to 2mm tread depth remaining.
Since I do not carry a spare, and run-flats are like driving plywood tires, I elected to replace these under Michelin's warranty and was give 50% credit to new tires.
If you have staggered fitment on your car, the 45,000 mile warranty goes down to 22,500 per Michelin's warranty. That means I should be able to get at least that or somewhat close to 22,500.
I've never worn tires bald on the tire's center on ANY BMW I've owned (3 to date). And on a sports car like this I budget getting 15-17k miles per set.
So, these are great tires for feel, driveability, comfort and performance. I'm quite surprised to get only 11k miles out of them.
Am I satisfied with these tires? Yes. Am I satisfied with Michelin's warranty? Yes.
I'd like to hear your feedback along with miles driven. At this rate I'll be buying tires again for this car in 12 months :-(
