Michelin North America introduced the MICHELIN XDR 3 surface-mine haul tire in size 27.00R49 for rigid dumpers with a 400-ton-payload capacity. The tire is designed with new compounds, corrosion-isolating cables, and a revolutionary tread pattern that helps provide exceptional tire life, the company reported. The design allows customers to choose between increased speed and load for the same tire life as predecessor competition or reduced speed and load for increased life. The tread pattern provides excellent load distribution across the contact patch, lowers contact pressure and reduces wear rate, the company reported. It also dissipates heat, improving tire life. The XDR3 is MEMS-ready and reduces rim slip through a new flat-bead wire, which is designed to strengthen the clamping force on the wheel and increase its contact surface with the rim, the company reported.
