Tire Pressure for High-Speed Operation

Driving at high speeds, 160 km/h (100 mph) or higher, puts an additional strain on tires. WARNING
Driving at high speeds, 160 km/h (100 mph) or higher, puts an additional strain on tires.

Sustained high-speed driving causes excessive heat buildup 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 P235/50R18 size tires require inflation pressure adjustment when driving the vehicle at speeds of 160 km/h (100 mph) or higher.

Set the cold inflation pressure to 270 kPa (39 psi).

Vehicles with P245/40R19 size tires require inflation pressure adjustment when driving the vehicle at speeds of 160 km/h (100 mph) or higher.

Set the cold inflation pressure to 310 kPa (45 psi).

Return the tires to the recommended cold tire inflation pressure when high-speed driving has ended. See Vehicle Load Limits  and Tire Pressure .
