If using winter tires:
•
U
s
e tires of the same brand and tread type
on all four wheel positions.
•
Use only radial ply tires of the same size,
load range, and speed rating as the original
equipment tires.
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. If
winter tires with alower speed rating are
chosen, never exceed the tire's maximum
speed capability.
All-Terrain Tires
This vehicle may have all-terrain or mud-terrain
tires. These tires provide good performance on
most road surfaces, weather conditions, and for
off-road driving. See Off-Road Driving 3157.
The tread pattern on these tires may wear more
unevenly than other tires. Consider rotating
the tires more frequently than at 12 000 km
(7,500 mi) intervals if irregular wear is noted
when the tires are inspected. See Tire Inspection
3260.
Tire Sidewall Labeling
Us
eful information about atire is molded
into its sidewall. The examples show
atypical passenger vehicle tire and
acompact spare tire sidewall.
Passenger Tire Example
(1) Tire Size : The tire size is acombination
of letters and numbers used to define
aparticular tire's width, height, aspect
ratio, construction type, and service
description. See the “Tire Size” illustration
in this section.
(2) TPC Spec (Tire Performance Criteria
Sp
ecification) : Original equipment tires
designed to GM's specific tire performance
criteria have aTPC specification code
molded onto the sidewall. GM's TPC
specifications meet or exceed all federal
safety guidelines.
(3) DOT (Department of Transportation) :
The Department of Transportation
(DOT) code indicates that the tire
is in compliance with the U.S.
Department of Transportation Motor
Vehicle Safety Standards.
DOT Tire Date of Manufacture : The last
four digits of the TIN indicate the tire
manufactured date. The first two digits
represent the week and the last two digits,
the year. For example, the third week of
the year 2020 would have a4-digit DOT
date of 0320. Week 01 is the first full week
(Sunday through Saturday) of each year.
