Mud tires are expensive. They can run from $150 to $800 each, a lot of money for some of us. A set of quality tires can quickly be destroyed by a misaligned suspension or poor tire maintenance. The mud tires on our Dodge were experiencing cupping, which caused the tread blocks to wear unevenly. There was 1/4 inch difference from block to block. The uneven tread wear made the truck ride at almost all speeds as if it had a death wobble. The irregular wear was caused by the passenger side toe being out of alignment.
