MICHELIN PILOT SPORT A MW1 - Specially designed for driving on rainy and dry roads. The MICHELIN Pilot Sport A MW1 has a notch rate(1) that is twice as high as the MICHELIN Pilot Sport R P01, giving it excellent water evacuation. The transverse notches also allow it to find traction in the event of a change in grip (polluted roads, mud, gravel, etc.).
