I've only got 4500 miles on mine so far. I was impressed with winter traction here in MN this winter. Anyway, they don't look like they have any wear on them. I'm running them at 40 psi.
Yep, the tread depth was certainly true between my tires - the one bought directly from Firestone was Significantly deeper.Many times an oem tire does not have the same ratings at its equivalent in aftermarket. When a car company buys tires for a car, they must meet certain mpg ratings, noise, comfort etc. A lot of the time the oem tires have less tread depth than ones you buy at the store. However, this is not true with Michelins.
The Primacy MXV4 is no longer. Michelin just released the Premier A/S line of tires replacing them. They look like they are going to be a great tire.
