HTR Enhance L/X tires featuring T-speed rated sizes are Sumitomo's Standard Touring All-Season tires developed for the drivers of family coupes and sedans. Designed to combine extra long treadwear with good ride comfort, HTR Enhance L/X tires provide all-season traction in dry, wet and wintry conditions, even in occasional light snow.HTR Enhance L/X tires feature Sumitomo's all-season compound molded into a 5-rib asymmetric tread pattern that blends ride stability with even wear. Wide outboard shoulder blocks, interlocked intermediate blocks and a notched center rib enhance handling and cornering stability. Four circumferential and long lateral grooves promote water evacuation that resists hydroplaning and enhances wet traction. Strategic Tread Block siping increases all-season capability and promotes long treadlife by resisting irregular treadwear.The tire's internal structure includes twin steel belts reinforced by Sumitomo's spirally wound Jointless Nylon Band (JNB) technology to increase highway stability and long-term strength. Tuned sidewall stiffness promotes handling while a polyester carcass helps absorb road disturbances to increase ride quality.
