including the spare.
SeeTires0252andTire Pressure0260for more information onproper tire inflation.
When It Is Time for New
Tires
Factors such as maintenance,temperatures, driving speeds,vehicle loading, and road conditionsaffect the wear rate of the tires.
Treadwear indicators are one way totell when it is time for new tires.Treadwear indicators appear whenthe tires have only 1.6 mm (1/16 in)or less of tread remaining.
Some commercial truck tires,including Goodyear LT225/75R16G949 RSA and Goodyear LT225/75R16 G933 RSD, may not havetreadwear indicators. If the tires donot have treadwear indicators,replace the tires when the treaddepth is down to 3.2 mm (1/8 in) forthe front tires, or 1.6 mm (1/16 in) forthe rear tires. SeeTire Inspection0265andTire Rotation0265foradditional information.
The rubber in tires ages over time.This also applies to the spare tire,if the vehicle has one, even if it isnever used. Multiple factorsincluding temperatures, loadingconditions, and inflation pressuremaintenance affect how fast agingtakes place. GM recommends thattires, including the spare ifequipped, be replaced after sixyears, regardless of tread wear. Thetire manufacture date is the last fourdigits of the DOT Tire IdentificationNumber (TIN) which is molded intoone side of the tire sidewall. Thefirst two digits represent the week(01-52) and the last two digits, theyear. For example, the third week ofthe year 2010 would have afour-digit DOT date of 0310.

{Warning
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tires not recommended for those
wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tire systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.

Uniform Tire Quality
Grading
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration
(NHTSA), which grades tires by
treadwear, traction, and
temperature performance. This
applies only to vehicles sold in
the United States. The grades
are molded on the sidewalls of
most passenger car tires. The
Uniform Tire Quality Grading
(UTQG) system does not apply
to deep tread, winter tires,
compact spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production
tires.
While the tires available on
General Motors passenger cars
and light trucks may vary with
respect to these grades, they
must also conform to federal
safety requirements and
additional General Motors Tire
Performance Criteria (TPC)
standards.
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:
Treadwear 200 Traction AATemperature A
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition To
These Grades.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. For example, a tire
graded 150 would wear one and
one-half (1Ω) times as well on
the government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of
their use, however, and may
depart significantly from the
norm due to variations in driving
habits, service practices and
differences in road
characteristics and climate.
Chevrolet Express Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-9967827) - 2017 - crc - 5/2/16
Vehicle Care 271
Traction
The traction grades, from
highest to lowest, are AA, A, B,
and C. Those grades represent
the tire's ability to stop on wet
pavement as measured under
controlled conditions on
specified government test
surfaces of asphalt and
concrete. A tire marked C may
have poor traction performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering,
hydroplaning, or peak traction
characteristics.
Temperature
The temperature grades are A
(the highest), B, and C,
representing the tire's resistance
to the generation of heat and its
ability to dissipate heat when
tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained
high temperature can cause the
material of the tire to degenerate
and reduce tire life, and
excessive temperature can lead
to sudden tire failure. The grade
Ccorrespondstoalevelof
performance which all
passenger car tires must meet
under the Federal Motor Safety
Standard No. 109. Grades B and
Arepresenthigherlevelsof
performance on the laboratory
test wheel than the minimum
required by law. Warning: The
temperature grade for this tire is
established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
Wheel Alignment and Tire
Balance
The tires and wheels were alignedand balanced at the factory toprovide the longest tire life and bestoverall performance. Adjustments towheel alignment and tire balancingare not necessary on a regularbasis. Consider an alignment checkif there is unusual tire wear or thevehicle is significantly pulling to oneside or the other. Some slight pull tothe left or right, depending on thecrown of the road and/or other roadsurface variations such as troughsor ruts, is normal. If the vehicle isvibrating when driving on a smoothroad, the tires and wheels may needto be rebalanced. See your dealerfor proper diagnosis.
Wheel Replacement
Replace any wheel that is bent,cracked, or badly rusted orcorroded. If wheel nuts keep comingloose, the wheel, wheel bolts, andwheel nuts should be replaced.If the wheel leaks air, replace it.

Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle warranty. Trying to start
the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.
1. Check the other vehicle.It must have a 12-volt batterywith a negative ground system.
Caution
If the other vehicle does not have
a12-voltsystemwithanegative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Get the vehicles close enoughso the jumper cables canreach, but be sure the vehiclesare not touching each other.If they are, it could cause a
ground connection you do notwant. You would not be able tostart your vehicle, and the badgrounding could damage theelectrical systems.
To a v o i d t h e p o s s i b i l i t y o f t h evehicles rolling, set the parkingbrake firmly on both vehiclesinvolved in the jump startprocedure. Put an automatictransmission in P (Park) or amanual transmission in Neutralbefore setting the parkingbrake.
Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn off the ignition on bothvehicles. Unplug unnecessaryaccessories plugged into the
cigarette lighter or theaccessory power outlet. Turnoff the radio and all lamps thatare not needed. This will avoidsparks and help save bothbatteries. And it could save theradio!
4. Open the hoods and locate thepositive (+) and negative (✓)terminal locations of the othervehicle.
On your van, use the unpaintedradio antenna bracket as aremote negative (✓)terminal.
{Warning
Using a match near a battery can
cause battery gas to explode.
People have been hurt doing this,
and some have been blinded.
Use a flashlight if you need more
light.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in

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.
