Hard rubber compound make wheels last longer, although this negatively impacts their traction when driving on tough terrain.Such wheels often come with enticing treadwear warranties that fully or partially cover the tire cost should you fail to reach the expected mileage under warranty.Unfortunately, this option dictates that you sacrifice performance for longevity. Not a worthy choice for the truck tires.Mud tires with soft rubber compounds often come with lower treadwear mileage warranties or no warranties at all.While the longevity of soft rubber compounds is lower, these compounds ensure better traction in all conditions, especially muddy, wet or wintery roads.You need to decide whether durability or performance is your priority.
