Pontiac 2009 Vibe Owner's Manual page 227

GM recommends replacing tires
in sets of four. This is because
uniform tread depth on all tires will
help keep the vehicle performing
most like it did when the tires were
new. Replacing less than a full set
of tires can affect the braking and
handling performance of the vehicle.
See Tire Inspection and Rotation on
page 9-53.

CAUTION
Mixing tires could cause you to
lose control while driving. If you
mix tires of different sizes,
brands, or types (radial and
bias-belted tires), the vehicle
may not handle properly, and
you could have a crash. Using
tires of different sizes, brands,
or types may also cause
CAUTION (Continued)
damage to the vehicle.
Be sure to use the correct
size, brand, and type of tires
on all wheels. It is all right
to drive with the compact
spare temporarily, as it was
developed for use on the
vehicle. See Compact
Spare Tire on page 9-70.
If you use bias-ply tires on the
vehicle, the wheel rim flanges
could develop cracks after
many miles of driving. A tire
and/or wheel could fail
suddenly, causing a crash.
Use only radial-ply tires with
the wheels on the vehicle.

CAUTION
Vehicles that have a tire pressure
monitoring system could give
an inaccurate low-pressure warning
if tires not recommended for the
vehicle are installed. Tires that do
not match the original equipment
tires could give a low-pressure
warning that is higher or lower
than the proper warning level you
would get with original equipment
tires. See Tire Pressure Monitor
System on page 9-48.
The vehicle's original equipment
tires are listed on the Tire and
Loading Information Label. See
Loading the Vehicle on page 8-32,
for more information about the
Tire and Loading Information label
and its location on the vehicle.
