2007 Dodge Ram 1500 Pickup Owner's Manual - Page 375

STARTING AND OPERATING 375 Improper alignment will not cause vehicle vibration. Vibration may be a result of tire and wheel out-ofbalance. Proper balancing will reduce vibration and avoid tire cupping and spotty wear. SUPPLEMENTAL TIRE PRESSURE INFORMATION - IF EQUIPPED A light load vehicle condition is defined as two passengers {150 lbs (68 kg) each} plus 200 lbs (91kg) of cargo. Cold tire inflation pressures for a lightly loaded vehicle will be found on the face of the driver's door. TIRE CHAINS Use "Class S" chains on 1500 Ram Trucks, or other traction aids that meet SAE Type "S" specifications. Use "Class U" chains on 2500/3500 Ram Trucks, or other traction aids that meet SAE Type "U" specifications. NOTE: Chains must be the proper size for the vehicle, as recommended by the chain manufacturer. CAUTION! To avoid damage to your vehicle, tires or chains, observe the following precautions: • Because of limited chain clearance between tires and other suspension components, it is important that only chains in good condition are used. Broken chains can cause serious vehicle damage. Stop the vehicle immediately if noise occurs that could suggest chain breakage. Remove the damaged parts of the chain before further use. Install chains as tightly as possible and then retighten after driving about 1/2 mile (0.8 km). Do not exceed 45 mph (72 km/h). Drive cautiously and avoid severe turns and large bumps, especially with a loaded vehicle. Do not install tire chains on front wheels of 4x2 vehicles. Do not drive for a prolonged period on dry pavement. Observe the tire chain manufacturer's instructions on method of installation, operating speed, and conditions for usage. Always use the lower suggested operating speed of the chain manufacturer if different than the speed recommended by the manufacturer. 5
