Tire durability was also improved with changes to the compounds in the tread and base, which helps reduce overall heat generation and improves the cut, chip and wear of the tire. Titan also removed the steel from the sidewalls of the tire, providing for a more durable carcass, while the lower sidewall flange features a new compound and profile for added durability. The tire’s new narrow profile eliminates potential interference issues with haul trucks. Sizes offered include 59/80R63, 53/80R63, 40.00R57 and 27.00R49.
