The Wrangler MT/R with Kevlar® (MT/R - Maximum Traction/Reinforced) is Goodyear's Off-Road Maximum Traction tire developed for light truck driving enthusiasts who take off-road traction seriously. The Wrangler MT/R with Kevlar is designed to increase tire toughness when it conquers mud, crawls over rocks and explores trails.The Wrangler MT/R with Kevlar features a silica rubber tread compound molded into an asymmetric tread design that combines off-road traction with on-road handling and wet traction. Goodyear's advanced mud-flow geometry tread design enhances self-cleaning capabilities while shoulder blocks (which alternate being stepped in and out) and a wraparound tread design on the upper sidewall increase traction in mud, sand, ruts and rocks. The tire's internal structure features twin steel belts and is Goodyear's first off-road tire to incorporate Dupont Kevlar, an innovative material that's, pound for pound, five times stronger than steel. The use of Kevlar sidewall reinforcement brings enhanced cut and puncture resistance to an area of the tire that demands extra toughness when driving off-road (increasing sidewall cut and puncture resistance by about 35% compared to the original Wrangler MT/R). The Kevlar also helps stabilize the sidewalls when drivers return to the pavement for the ride home.Off-Road Maximum Traction light truck tires, which are often called mud tires, are branded with the M+S symbol, but their typical oversize applications, use of extra-large smooth lugs and minimal snow-biting sipes often challenges an Off-Road Maximum Traction tire's on-road wintertime traction in slush, packed snow and on ice.
