The Michelin Pilot Sport 4 SUV is an extension of the hugely successful Pilot Sport 4 and 4S product lines, which have been leading the ultra-high performance car segment for a number of years. Building on the already strong foundations, Michelin has adapted the tire to better handle the higher centre of gravity and heavier bodyweights SUVs generally have, and developed the PS4 SUV in conjunction with some of the most demanding SUV manufacturers, such as Porsche. Like the PS4, the new SUV tire has an asymmetric tread pattern with the outer part of the tread optimised for dry grip and cornering, and the inner part focused on providing the best grip possible when it’s wet. The construction of the tire is also improved, with a two layer high density casing ply and ridged tread blocks allowing the tire to keep Michelin's usual long tread life.
