The 22.5″ wheels are mounted with Turnpike front and Hankook rear tires. Work in the last 10 years has included replacing the front wheels and tires as well as recapping the rear tires. The seller states that a Freightliner air-ride suspension system is installed and that the front hubs, two rear axles, and the brake drums were replaced as part of the refurbishment. A rebuilt hydraulic steering system has also been added.
