Wheels and Tires
Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer. See
the warranty manual for
information regarding the tire
warranty and where to get
service. For additional
information refer to the tire
manufacturer.
{Warning
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a
result of too much
flexing. There could be a
blowout and a serious
crash. SeeVehicle Load
Limits0178.

(1) Passenger (P-Metric) Tire:
The United States version of a
metric tire sizing system. The
letter P as the first character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association.
(2) Tire Width:The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio:Atwo-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item 3 of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(4) Construction Code:Aletter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Service Description:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
windows, power seats, and air
conditioning.
Aspect Ratio:The relationship
of a tire's height to its width.
Belt:Arubbercoatedlayerof
cords between the plies and the
tread. Cords may be made from
steel or other reinforcing
materials.
Bead:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire:Apneumatictire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.

See your dealer for service or topurchase a relearn tool. A TPMSrelearn tool can also be purchased.See Tire Pressure Monitor SensorActivation Tool atwww.gmtoolsandequipment.com orcall 1-800-GM TOOLS(1-800-468-6657).
There are two minutes to match thefirst tire/wheel position, andfive minutes overall to match all fourtire/wheel positions. If it takeslonger, the matching process stopsand must be restarted.
The TPMS sensor matchingprocess is:
1. Set the parking brake.
2. Turn the ignition to ON/RUNwith the engine off or place thevehicle power mode in ON/RUN/START. SeeIgnitionPositions (Key Access)0182orIgnition Positions (KeylessAccess)0183.

your dealer. Follow all
manufacturer directions regarding
correct product usage, necessary
safety precautions, and
appropriate disposal of any
vehicle care product.
Caution
Avoid using high-pressure
washes closer than 30 cm (12 in)
to the surface of the vehicle. Use
of power washers exceeding
8,274 kPa (1,200 psi) can result
in damage or removal of paint
and decals.
Caution
Do not power wash any
component under the hood that
has thisesymbol.
(Continued)
Caution (Continued)
This could cause damage that
would not be covered by the
vehicle warranty.
If using an automatic car wash,follow the car wash instructions. Thewindshield wiper and rear windowwiper, if equipped, must be off.Remove any accessories that maybe damaged or interfere with the carwash equipment.
Rinse the vehicle well, beforewashing and after, to remove allcleaning agents completely. If theyare allowed to dry on the surface,they could stain.
Dry the finish with a soft, cleanchamois or an all-cotton towel toavoid surface scratches and waterspotting.
Finish Care
Application of aftermarket clearcoatsealant/wax materials is notrecommended. If painted surfacesare damaged, see your dealer to
have the damage assessed andrepaired. Foreign materials such ascalcium chloride and other salts, icemelting agents, road oil and tar, treesap, bird droppings, chemicals fromindustrial chimneys, etc., candamage the vehicle's finish if theyremain on painted surfaces. Washthe vehicle as soon as possible.If necessary, use non-abrasivecleaners that are marked safe forpainted surfaces to remove foreignmatter.
Occasional hand waxing or mildpolishing should be done to removeresidue from the paint finish. Seeyour dealer for approved cleaningproducts.
Do not apply waxes or polishes touncoated plastic, vinyl, rubber,decals, simulated wood, or flat paintas damage can occur.

284 Vehicle Care
Caution
To a v o i d s u r f a c e d a m a g e , d o n o t
use strong soaps, chemicals,
abrasive polishes, cleaners,
brushes, or cleaners that contain
acid on aluminum or
chrome-plated wheels. Use only
approved cleaners. Also, never
drive a vehicle with aluminum or
chrome-plated wheels through an
automatic car wash that uses
silicone carbide tire cleaning
brushes. Damage could occur
and the repairs would not be
covered by the vehicle warranty.
Brake System
Visually inspect brake lines andhoses for proper hook-up, binding,leaks, cracks, chafing, etc. Inspectdisc brake pads for wear and rotorsfor surface condition. Inspect drumbrake linings/shoes for wear orcracks. Inspect all other brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering,suspension, and chassiscomponents for damaged, loose,or missing parts or signs of wear atleast once a year.
Inspect power steering for properattachment, connections, binding,leaks, cracks, chafing, etc.
Visually check constant velocity jointboots and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders,hood hinges, liftgate hinges, and thesteel fuel door hinges, unless thecomponents are plastic. Applyingsilicone grease on weatherstripswith a clean cloth will make themlast longer, seal better, and not stickor squeak.
Underbody Maintenance
At least twice a year, spring and fall,use plain water to flush anycorrosive materials from the
underbody. Take care to thoroughlyclean any areas where mud andother debris can collect.
Do not directly power wash thetransfer case and/or front/rear axleoutput seals. High pressure watercan overcome the seals andcontaminate the fluid. Contaminatedfluid will decrease the life of thetransfer case and/or axles andshould be replaced.
Sheet Metal Damage
If the vehicle is damaged andrequires sheet metal repair orreplacement, make sure the bodyrepair shop applies anti-corrosionmaterial to parts repaired orreplaced to restore corrosionprotection.
Original manufacturer replacementparts will provide the corrosionprotection while maintaining thevehicle warranty.
Finish Damage
Quickly repair minor chips andscratches with touch-up materialsavailable from your dealer to avoid
