Buick Regal: Tire Pressure for High-Speed Operation
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 .
Tire Pressure
Tires need the correct amount of air pressure to operate effectively.
Notice: Neither tire underinflation nor overinflation is good.
Underinflated tires, or tires that do not have enough air, can re ...
