Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
High Speed Operation
{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 in ation 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
in ation pressure for the vehicle load.Vehicles equipped with 245/45ZR17 95W size tires,
do not require additional air pressure for high-speed
operation. If your vehicle has 235/40ZR18 91W
size tires, use the following chart to determine the cold
tire inflation pressure when operating your vehicle
under high-speed conditions.
