Chevrolet Silverado: Wheels and Tires / Tire Pressure for High-Speed Operation
Warning
Driving at high speeds, 160 km/h (100 mph) or higher, puts additional strain
on tires. Sustained high-speed driving causes excessive heat buildup and can cause
sudden tire failure. This could cause 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 allow the vehicle to be driven
at high speeds, make sure the tires are rated for high-speed operation, are in excellent
condition, and are set to the correct cold tire inflation pressure for the vehicle
load.
Tires need the correct amount of air pressure to operate effectively.
Warning
Neither tire underinflation nor overinflation is good. Underinflated tires,
or tires that do not have enough air, can result in:
Tire overloading and overheating, which could lead to a blowout...
The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check
tire pressure levels. The TPMS sensors monitor the air pressure in your tires and
transmit tire pressure readings to a receiver located in the vehicle...
Other information:
If equipped, Active Fuel Management allows the gasoline engine to operate on
either all of its cylinders, or a reduced number of cylinders, depending on the
driving conditions. When less power is required, such as cruising at a constant
vehicle speed, the system will enable reduced cylinder operation, allowing the vehicle
to achieve better fuel economy...
Adding non-dealer accessories or making modifications to the vehicle can affect
vehicle performance and safety, including such things as airbags, braking, stability,
ride and handling, emissions systems, aerodynamics, durability, and electronic systems
like antilock brakes, traction control, and stability control...
