      Benefits of Michelin:

      • MICHELIN Primacy™ tires are the #1 choice among top vehicle manufacturers for their premium and luxury models.[1]

        1 out of 4 premium vehicles sold in North America is equipped with MICHELIN® tires.

      • The MICHELIN Primacy™ Tour A/S has the quietest tread design among leading competitors.[2]

        Enhanced ComfortControl with PIANO Noise Reduction Tuning combines frequency cancelling shoulder grooves and block chamfers with ultra smooth belts resulting in an exceptionally quiet ride.

      • 17% better snow traction than the MICHELIN® Primacy™ MXM4®.[3]

        Latest generation of advanced rubber compound maintains tread block flexibility in cold temperatures to help grip on snow and ice, while sharp lateral groove angles bite into snow to handle turns with confidence in winter conditions.
