The AVID H4s/V4s radials are Yokohama's High Performance All-Season tires designed to take everyday driving to a new level of comfort and confidence. The AVID H4s/V4s radials were developed to provide sporty cars, coupes and sedans with good treadwear, responsive handling and year-round traction, even in light snow. On the outside, Yokohama developed an all-new tread compound for the AVID H4s/V4s radials that delivers grip on dry, wet and snow-covered roads while setting new high mileage levels for H- and V-speed rated performance tires at Yokohama. This new tread compound is molded into a computer-optimized directional tread design that combines large independent shoulder blocks and intermediate blocks with a solid center rib to enhance straight line tracking and high-speed stability on dry roads. Four wide circumferential grooves and multiple cross grooves effectively evacuate water for hydroplaning resistance while slightly offset tread blocks further enhance light snow traction. On the inside, the AVID H4s/V4s features twin, high-tensile steel belts reinforced by nylon belt edge strips to provide responsive handling and high-speed durability.
