When It Is Time For New Tires - Cadillac 2012 SRX Owner's Manual

10-64 Vehicle Care
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10 59.
Check that all wheel nuts
are properly tightened.
See Wheel Nut Torque under
Capacities and Specifications on
page 12 2.
WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle.
WARNING (Continued)
In an emergency, a cloth or a
paper towel can be used;
however, use a scraper or wire
brush later to remove all rust
or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.

When It Is Time for
New Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way
to tell when it is time for new tires.
Treadwear indicators appear
when the tires have only 1.6 mm
(1/16 in) or less of tread remaining.
