4x4 Diamaris P275/40R20

The 4x4 Diamaris is Michelin's Street/Sport Truck Summer tire that provides their highest level of wet and dry traction for luxury sport utility vehicles. Used as original equipment on the BMW X5 4.6is, Porsche Cayenne S and Cayenne Turbo, the 4x4 Diamaris is also available in the large rim diameter sizes appropriate for other light trucks. The 4x4 Diamaris molds a wet weather tread compound into an asymmetric tread design that features large outer shoulder blocks contributing to steering response and cornering confidence. A continuous center rib enhances steering precision and high-speed stability while two wide, circumferential and multiple lateral grooves channel water to reduce the possibility of hydroplaning. The tire's internal structure includes two high-tensile steel belts reinforced by Michelin's BAZ technology (spiral wrapped nylon Banded At Zero degrees to tire rotation) to enhance stability at high speeds while improving tire uniformity and reducing weight to ensure even ride quality.
