3 Tough Tires For A Tough Job Mining represents one of the most severe operating environments for any tire. To meet this challenge, Goodyear has designed a complete range of specially constructed tires to provide optimum treadwear, traction, and cut resistance. High Strength Casings The body of a Goodyear bias mine tire is composed of a specially processed 3-T nylon cord, which provides superior fatigue and bruise resistance. The Goodyear radial mine tire incorporates steel cable for ultimate strength and cut resistance. Tough Tread Compounds Goodyear has developed a family of abrasion and ultra abrasion resistant compounds, which greatly increase tread wear and resist cuts and snags. Full Range Of Tread Designs Since job conditions vary from mine to mine, Goodyear offers a full range of tread patterns one is just right for your operation. World Wide Sourcing Goodyear produces mine tires in key plants around the world. Check your Goodyear representative for availability in your specific location.
