– The Goodyear Tire & Rubber Company has another addition to its Wrangler tire lineup — the Wrangler featuring SilentArmor Technology Pro-Grade. Sporting a new tread compound and enhanced toughness and treadwear capability, the new Wrangler SilentArmor Pro-Grade features a new, chip- and chunk-resistant tread compound, enhancing tread wear in heavy loading and towing applications. Two high-tensile steel belts and a layer made with DuPont KEVLAR (two layers of KEVLAR in Load Range E sizes) help absorb road noise and provide a smooth and quiet ride. The tire also features an enhanced Rim Lock, offering a more stable bead area to reduce rim slip for minimal balancing throughout the life of the tire and a Rugged Rim Guard, which helps protect expensive wheels from accidental curb damage.The Wrangler SilentArmor Pro-Grade also features a rugged tread pattern for a consistent tread contact patch, at a variety of load and speed conditions, to maximize traction in all conditions and enhance tread life and resistance to uneven wear. Traction ridges are also used within the tread of the tire for enhanced traction in wet or muddy conditions, and the tire bears the industry’s mountain-snowflake symbol, certifying it for “severe snow” usage.Wrangler SilentArmor Pro-Grade fits the Ford F-250 and F-350, Chevy and GMC 2500 and 3500 models, and Dodge 2500 and 3500, and more. Pro-Grade expands the availability of Goodyear’s SilentArmor Technology, currently available in 33 sizes covering P-metric, LT- metric, and high flotation applications for 15-18 inch rims, with 14 select LT sizes with load ranges D and E and rim diameters ranging from 16-20 inches. This 47-size lineup will continue to grow, with seven more sizes scheduled to be added in 2007.
