High Speed Operation (CTS-V)
{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 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.
The CTS-V performance series has 245/45R18 96W size
tires. These high-performance tires require inflation
pressure adjustment when driving your vehicle at speeds
of 130 mph (209 km/h) or higher with occupants and
cargo weighing 600 lbs. (272 kg) up to 882 lbs. (400 kg).
Use the following chart to determine the cold tire
inflation pressure when operating your vehicle under
these conditions.

When you end high-speed driving, return the tires to the
cold inflation pressures shown on the tire and loading
information label. See Loading Your Vehicle on
page 4-32.
