Tires, Wheels and Loading WHEELS Your vehicle may be equipped with two-piece bolt-together beadlock rims. Beadlock rims allow the tires to survive operating at lower air pressure which provide greater traction due to the larger tire-to-ground contact area during slow, off-road operation. Always reinflate the tires to the tire manufacturer's recommendations when no longer in slow, off-road driving conditions. The beadlock also acts as a safety device ensuring that the tire does not unseat from the rim or rotate on the wheel when tire pressure is reduced, while also preventing the entry of foreign objects, debris or water into the tire's air chamber. Note: The wheel/tire assemblies should be serviced only by trained personnel who have read and understand the wheel assembly/disassembly information contained within the Workshop Manual. SNOW CHAINS Tire chains cannot be used on vehicles equipped with M/TR tires. ON-BOARD AIR SYSTEM Your vehicle is equipped with an on-board air system which has been designed to provide compressed air for multiple uses, including the addition of air to the vehicle's tires. The system uses a 25 ft. (7.6m) length of air hose equipped with a clamp-on style air chuck. When not in use, this hose is secured to the floor of the truck. A compressor, mounted to the frame under the truck on the passenger side frame rail, is included along with an air reservoir on the driver side. When the compressor is on, the output pressure at the air tank is limited to 80 psi (552 kPa). The air coupling, to which the hose is to be connected, is located just above the floor behind the driver's seat. 8
