Energy MXV4 S8 Tires are Michelin's best-selling and most popular Grand Touring All-Season tires developed to meet the needs of sporty coupe and luxury performance sedan drivers. Michelin Energy MXV4 Plus tires are designed to offer a high level of comfort, long tread life, consistent and precise handling and all-season traction, including in light snow. Energy MXV4 Plus tires incorporate an advanced version of Michelin's Radial XSE Technology (which consists of a Smart Tread Compound, Optimized Casing Shape and Optimized Mass Distribution) and use Michelin's silica-based rubber compounds that help resist wear, improve fuel economy, and hold the road. This compound is molded into a seven-rib tread design that provides more grooves to enhance foul weather traction. It also incorporates offset shoulder and diagonal intermediate blocks that are designed to "flow" through the contact patch for a quiet ride. The tire's structure includes a rounded casing shape to provide predictable handling, and has been optimized to equalize the tire's footprint pressure to extend its tread life. BAZ Technology (spirally wrapped nylon, Banded At Zero degrees) reinforces the Energy MXV4 Plus' twin steel belts to provide high-speed durability while it helps maintain ride comfort.
