The P4000 Super Touring successfully combines tire characteristics that were generally considered to be mutually exclusive. It's an all-season, high-performance tire. Yet it also delivers outstanding comfort and treadlife. Which means superlative wet grip, hydroplaning resistance and snow traction of a world-class, all-season tire. But without the typical compromises of a noticeably harsher and noisier ride. Much of the credit for these significant refinements must go to Pirelli's extensive use of Computer Aided Engineering and Testing (CAE/CAT). As a result, the P4000 Super Touring's highly flexible sidewalll is better able to absorb the shocks from road suffices and obstacles without compromising its lateral or cornering stiffness.
