Tire Pressures For High-Speed Operation

The manufacturer advocates driving at safe speeds within posted speed limits. Where speed limits or conditions are such that the vehicle can be driven at high speeds, maintaining correct tire inflation pressure is very important. Increased tire pressure and reduced vehicle loading may be required for high-speed vehicle operation.

Refer to original equipment or an authorized tire dealer for recommended safe operating speeds, loading and cold tire inflation pressures.

WARNING!
High speed driving with your vehicle under load is dangerous. The added strain on your tires could cause them to fail. You could have a serious collision.

Do not drive a vehicle loaded to maximum capacity at continuous speeds above 75 mph (120 km/h).
