Cadillac 2006 CTS-V, Owner'S Manual, Page: 343 / 434

If your vehicle has run-flat tires, the Tire Pressure
Monitor (TPM) system will need to have the sensors
reset after a tire rotation is performed. A special tool
is needed to reset the sensor identification codes.
See your dealer for service.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” under Capacities and
Specifications on page 5-114.

CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if needed, to get
all the rust or dirt off. See Changing a Flat Tire
(CTS Only) on page 5-84.
When It Is Time for New Tires
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.
You need a new tire if any of the following statements
are true:
•
You can see the indicators at three or more places
around the tire.
•
You can see cord or fabric showing through the
tire’s rubber.
•
The tread or sidewall is cracked, cut, or snagged
deep enough to show cord or fabric.
•
The tire has a bump, bulge, or split.
•
The tire has a puncture, cut or other damage that
cannot be repaired well because of the size or
location of the damage.
