All Seasons radial tires qualify as snow tires, with a 37 percent higher average rating for snow traction than non-All Seasons radial tires. Other performance areas that were slightly improved are listed below:

    • Wet traction
    • Rolling resistance
    • Tread life
    • Air retention

This was done by improvements in both tread design and tread compounds. These tires are identified by an M+S molded in the tire sidewall following the size. The suffix MS is also molded in the sidewall after the TPC specification number.
