Tires: 6 INSPECTION AND MAINTENANCE Tire Inspection Inspect your vehicle's tires at least once a month by performing the following checks: 1) Measure the air pressure with a tire gauge. Adjust the pressure if necessary. Remember to check the spare tire, too. Refer to the "Measuring Air Pressure" section. 1.6 mm (0.06 in.) or less and the tire should be replaced. 3) Check for abnormal wear, cracks and damage. Any tires with cracks or other damage should be replaced. If any tires show abnormal wear, have them inspected by your SUZUKI dealer. WARNING Hitting curbs and running over rocks can damage tires and affect wheel alignment. Be sure to have tires and wheel alignment checked periodically by your SUZUKI dealer. 4) Check for loose wheel nuts. 5) Check that there are no nails, stones or other objects sticking into the tires. 54G136 WARNING Your SUZUKI is equipped with tires which are all the same type and size. This is important to ensure proper steering and handling of the vehicle. Never mix tires of different size or type on the four wheels of your vehicle. The size and type of tires used should be only those approved by SUZUKI Motor Corporation as standard or optional equipment for your vehicle. CAUTION For intelligent All Wheel Drive (iAWD) models, replacing a tire with one of a different size, or using different brands among the four tires can result in damage to the drive train.
