196 STARTING AND OPERATING Improper alignment will not cause vehicle vibration, which may be a result of tire and wheel out-of-balance. Proper balancing will reduce vibration and avoid tire cupping and spotty wear. TIRE CHAINS Install chains on rear tires only. Tire chains may be installed on all models except Sahara. Follow these recommendations to guard against damage and excessive tire and chain wear: • Use chains on P205/75R15 or P215/75R15 tires only. P225/75R15, LT30 x 9.50R15, and LT245/75R16 tires do not provide adequate clearance. • Use SAE class "S" tire chains or traction devices only. • Chains must be the proper size for the vehicle, as recommended by the chain manufacturer. • Follow tire chain manufacturer's instructions for mounting chains. • Install chains snugly and tighten after.6 mile (1 km) of driving. • Do not exceed 30 mph (48 km/h). • Drive cautiously, avoiding large bumps, potholes and extreme driving maneuvers. • Do not use chains or traction devices on the Poly-spare tire. TIRE ROTATION RECOMMENDATIONS Tires on the front and rear axles of vehicles operate at different loads and perform different steering, handling, and braking functions. For these reasons, they wear at unequal rates, and develop irregular wear patterns. These effects can be reduced by timely rotation of tires. The benefits of rotation are especially worthwhile with aggressive tread designs such as those on On/Off Road type tires. Rotation will increase tread life, help to maintain mud, snow, and wet traction levels, and contribute to a smooth, quiet ride.
