Tools to Tackle Tire Life Challenges
Anyone watching, for the first time, the factory assembly process for a mining-class off-the-road tire is likely to be surprised at the number of individual components it takes to make these multiton giants. Typically, as many as 60 or 70 items of various size and composition -- ranging from rubber to rayon to steel -- are ultimately merged through heat and pressure into a deceptively simple-looking rubber donut engineered to survive the incredibly tough conditions encountered in mining applications. Tires need air, and the newest ones need more air than older models. For example, Michelin's XDR250 tire for 250-ton-class haulers, introduced in 2015, contains at least 9% more air than its predecessor, which allows it to carry heavier loads. The trend toward increased air capacity in giant-tire product lines is mainly a function of new lower-profile, wider-tread designs that are intended to reduce tire-to-ground contact pressure and thereby extend tread life. The extra width afforded by these designs results in a larger internal air chamber.
