Tires The factory-installed tires on your car were selected to provide the best performance for normal driving. Inflation Pressures The tire label on the driver's door jamb shows recommended tire pressures for carrying loads up to the limit shown. These pressures were chosen to provide you with the best combination of tread life, riding comfort and stability under normal driving conditions. Improper inflation can reduce TIRE LABEL both tire life and load carrying capacity. Check the tire pressures at least once a month, including the spare. Lower pressure than recommended lets the tread and sidewalls flex too much, causing increased tire temperatures, uneven wear, and poor handling. Pressure higher than recommended can make the tire too stiff, increasing the chance of damage from road hazards, and also causing uneven wear. CAUTION: Check tire pressure when the tires are cold. (After the car has been parked for more than 3 hours or driven less than 1 mile/1.6 km). Tire pressure may increase as much as 41 kPa (6 psi) when the tire is hot, so NEVER ADJUST tire pressure when the tires are hot. Never inflate load range B tires to more than 220 kPa (32 psi) cold. Cars with luggage racks or cartop carriers DO NOT have greater load limits than those on the label. Snow Tires If you use snow tires, they should have the same load capacity as the original equipment tires, and they must be installed in sets of four, or they may cause poor handling. Cars with snow tires should not be driven faster than 75 mph (120 km/h).
