The new Michelin Defender Series tires are able to achieve their long life through
MaxTouch Construction that optimizes the contact patch for long, even wear through the life of the tire.
The entire surface of the tire is computer designed to come in contact with the road surface so not only do you get better traction but much longer and even wear.
Michelin Tire achieved this by the way the belts are constructed in the tire to allow even pressure across the entire tread surface.
