TIRES OF FOUR-WHEEL DRIVE CAUTION Always use tires of the same type, size, brand, construction (bias, bias-belted or radial), and tread pattern on all four wheels. Failure to do so may result in a circumference difference between tires on the front and rear axles which will cause excessive tire wear and may damage the transmission, transfer case and differential gears. If excessive tire wear is found, it is recommended that all four tires be replaced with tires of the same size, brand, construction and tread pattern. The tire pressure and wheel alignment should also be checked and corrected as necessary. Contact an authorized NISSAN dealer. pressures are shown on the tire placard affixed to the glove box. Tire chain Tire chains must be installed only on the rear wheels and not on the front wheels. Do not drive with tire chains on paved roads which are clear of snow. Driving with chains in such conditions can cause damage to the various mechanisms of the vehicle due to some overstress. When driving on clear paved roads, be sure to change to 2WD. Snow tires If you install snow tires, they must also be the same size, brand, construction and tread pattern on all four wheels. Tire inflation pressure Periodically check the pressure in all tires, including the spare, with a gauge. Adjust to the specified pressure if necessary. Tire 5-22 Starting and driving
