Large, stable tread blocks reduce squirm in the footprint, promoting stability, grip and tread wear in both the dry and the wet. Multiple lateral grooves and sipes maintain all-season traction for the life of the tire. Four deep circumferential tread grooves evacuate water from under the footprint minimizing the risk of hydroplaning. Computer optimized contour reduces tire internal stresses and increases overall tire durability. Tech 9 tyres will not only match, but will beat any competitor’s price. That’s the Tech 9 Guarantee!
