19a Notice the treadwear rating between the BFG Comp T/A (000) and the Nitto NT555R (100). Regular street tires usually have a treadwear rating between 350 to 600. The higher the treadwear number, the longer they last. Past experience using both brand of tires has shown us the BFG to last between 3,000 to 4,000 miles. The Nitto has lasted us roughly 5,000 miles with the same street/strip use.
