yokohama introduces new geolandar h t4 all season highway tire Yokohama Tire has introduced a new addition to its GEOLANDAR lineup, the GEOLANDAR H/T4. This all-season highway tire is designed for light trucks, SUVs, and commercial vans, and is offered in 62 sizes ranging from 15- to 22-inch wheel diameters. According to Kevin Nguyen, Yokohama Tire's manager of product planning, the H/T4 continues the company's lineup of highway-focused tires. It's intended to deliver a balance of durability, ride comfort, and all-season capability for everyday driving. The tire also comes with a 70,000-mile limited treadwear warranty for Euro-metric sizes and a 55,000-mile warranty for LT-metric sizes. The tread design focuses on maintaining traction in different conditions. Dual lug grooves and wide circumferential channels help manage water and reduce the risk of hydroplaning, while the tread pattern is shaped to support grip in wet and light snow conditions. Ride comfort is addressed through a multi-pitch tread pattern that helps reduce road noise. The shoulder blocks are designed to stay rigid over time, which helps keep noise levels consistent as the tire wears. For durability, Yokohama uses a compound aimed at handling the added stress of hauling and towing. The tire also features a dual sidewall design, with one side offering additional protection against road hazards. To extend tread life, the H/T4 uses triple 3D sipes that help stabilize the tread blocks and promote more even wear. The compound also incorporates a mix of silica and carbon intended to support tread longevity, fuel efficiency, and wet traction.
