1996 Ford Bronco Owner's Manual - Page 301

Checking the pressure of the tires At least once a month, check the pressure in all your vehicle's tires, including the spare. Use an accurate tire pressure gauge. Check the tire pressure when tires are cold, that is, after the vehicle has been parked for at least one hour or has been driven less than 3 miles (5 km). You can find the proper cold pressure on the Safety Compliance Certification Label. RWARNING Improperly inflated tires can affect vehicle handling and can fail suddenly, possibly resulting in loss of vehicle control. Tire inspection and maintenance Inspect the tire treads, and remove stones, nails, glass or other objects that may be wedged in the tread grooves. Check for holes or cuts that may permit air to leak from the tire, and make the necessary repairs. Inspect the tire side walls for cuts, bruises and other damage. If you suspect internal damage to the tire, have it demounted and checked. You may need to repair or replace it. Wheel inspection and maintenance Check for damage that would affect the runout of the wheels. Wobble or shimmy will eventually damage the wheel bearings. Front wheel bearings require periodic repacking and adjustment as specified in the Maintenance Schedule and Record booklet. Loose or worn front wheel bearings tend to let the vehicle wander or shimmy, and can eventually cause excessive tire wear. 304
