Caution: Driving at high speeds, 100 mph (160 km/h) or higher, puts an additional strain on tires. Sustained high-speed driving causes excessive heat build up and can cause sudden tire failure. You could have a crash and you or others could be killed. Some high-speed rated tires require inflation pressure adjustment for high speed operation. When speed limits and road conditions are such that a vehicle can be driven at high speeds, make sure the tires are rated for high speed operation, in excellent condition, and set to the correct cold tire inflation pressure for the vehicle load.
Vehicles with P245/45R18 100V XL, 245/45R18 96V, P245/40R19 94W or 245/40R19 94W size tires, require inflation pressure adjustment when driving the vehicle at speeds of 100 mph (160 km/h) or higher. Use the following chart to determine the cold tire inflation pressure when operating the vehicle under high-speed conditions.
Tire Size | Recommended Cold Tire Inflation | |||
|---|---|---|---|---|
Occupant and Cargo Weight: 573 lbs (260 kg) or Less | Occupant and Cargo Weight: Up to 917 lbs (416 kg) (Vehicle Capacity Weight) | |||
Front Tires | Rear Tires | Front Tires | Rear Tires | |
P245/45R18 100V XL | 35 psi (240 kPa) | 35 psi (240 kPa) | 39 psi (270 kPa) | 44 psi (300 kPa) |
245/45R18 96V | 36 psi (250 kPa) | 36 psi (250 kPa) | 39 psi (270 kPa) | 44 psi (300 kPa) |
245/40R19 94W | 36 psi (250 kPa) | 36 psi (250 kPa) | 39 psi (270 kPa) | 44 psi (300 kPa) |
P245/40R19 94W | 35 psi (240 kPa) | 35 psi (240 kPa) | 39 psi (270 kPa) | 44 psi (300 kPa) |
When you end this high-speed driving, return the tires to the cold tire inflation pressure shown on the Tire and Loading Information label. See Loading the Vehicle and Inflation - Tire Pressure.
