BrightDrop Zevo 600 Owner Manual (GMNA-Localizing-U.S./Canada-
16569273) - 2023 - CRC - 11/3/22
Vehicle Care 201
GM's TPC Spec number is molded onto
the tire's sidewall near the tire size.
If the tires have an all-season tread
design, the TPC Spec number will be
followed by MS for mud and snow. See
Tire Sidewall Labeling 0 191 for
additional information.
GM recommends replacing worn tires in
complete sets of four (six for dual rear
wheels). Uniform tread depth on all
tires will help to maintain the
performance of the vehicle. Braking and
handling performance may be adversely
affected if all the tires are not replaced
at the same time. If proper rotation and
maintenance have been done, all four
tires (six for dual rear wheels) should
wear out at about the same time.
However, if it is necessary to replace
only one axle set of worn tires, place
the new tires on the rear axle (two for
single rear wheels, four for dual rear
wheels). See Tire Rotation 0 198.

Warning
Tires could explode during improper
service. Attempting to mount or
dismount a tire could cause injury or
death. Only your dealer or authorized
tire service center should mount or
dismount the tires.
{
Warning
Mixing tires of different sizes (other
than those originally installed on the
vehicle), brands, tread patterns,
or types may cause loss of vehicle
control, resulting in a crash or other
vehicle damage. Use the correct size,
brand, and type of tire on all wheels.
{
Warning
Using bias-ply tires on the vehicle
may cause the wheel rim flanges to
develop cracks after many miles of
driving. A tire and/or wheel could fail

Warning (Continued)
suddenly and cause a crash. Use only
radial-ply tires with the wheels on
the vehicle.
Winter tires with the same speed rating
as the original equipment tires may not
be available for H, V, W, Y and ZR
speed rated tires. Never exceed the
winter tires’ maximum speed capability
when using winter tires with a lower
speed rating.
If the vehicle tires must be replaced
with a tire that does not have a TPC
Spec number, make sure they are the
same size, load range, speed rating, and
construction (radial) as the original
tires.
The Tire and Loading Information label
indicates the original equipment tires
on the vehicle. See Vehicle Load Limits
0 117.
