When It Is Time For New Tires - Buick 2008 Lucerne Owner's Manual

After the tires have been rotated, adjust the
front and rear inflation pressures as shown on
the Tire and Loading Information label. See
Inflation - Tire Pressure on page 5-67 and Loading
Your Vehicle on page 4-19.
Reset the Tire Pressure Monitor System. See Tire
Pressure Monitor Operation on page 5-70.
Make certain that all wheel nuts are properly
tightened. See "Wheel Nut Torque" under
Capacities and Specifications on page 5-113.
CAUTION:
{
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
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 on page 5-84.

When It Is Time for New Tires

Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions
influence when you need 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.
