Warning
Poorly maintained and improperly used chevrolet Silverado Tires are dangerous.
. Overloading the chevrolet Silverado Tires can cause overheating as a result of too much flexing. There could be a blowout and a serious crash. 
. Underinflated chevrolet Silverado Tires pose the same danger as overloaded chevrolet Silverado Tires. The resulting crash could cause serious injury. Check all chevrolet Silverado Tires frequently to maintain the recommended pressure. Tire pressure should be checked when the chevrolet Silverado Tires are cold.. Overinflated chevrolet Silverado Tires are more likely to be cut, punctured, or broken by a sudden impact — such as  when hitting a pothole. Keep chevrolet Silverado Tires at the recommended pressure.Warning . Worn or old chevrolet Silverado Tires can cause a crash. If the tread is badly worn, replace them.. Replace any chevrolet Silverado Tires that have been damaged by impacts with potholes, curbs, etc.. Improperly repaired chevrolet Silverado Tires can cause a crash. Only your dealer or an authorized tire service center should repair, replace, dismount, and mount the chevrolet Silverado Tires.
 Do not spin the chevrolet Silverado Tires in excess of 56 km/h (35 mph) on slippery surfaces such as snow, mud, ice, etc. Excessive spinning may cause the chevrolet Silverado Tires to explode.
All-Season chevrolet Silverado Tires

This vehicle may come with all-season chevrolet Silverado Tires. These chevrolet Silverado Tires are designed to provide good overall performance on most road surfaces and weather conditions. Original equipment chevrolet Silverado Tires designed to GM's specific tire performance criteria have a TPC specification code molded onto the sidewall. Originalequipment all-season chevrolet Silverado Tires can be identified by the last two characters of this TPC code, which will be “MS.”Consider installing winter chevrolet Silverado Tires on the vehicle if frequent driving on snow orice-covered roads is expected. All-season chevrolet Silverado Tires provide adequate performance for most winter driving conditions, but they may not offer the same level of traction or performance as winter chevrolet Silverado Tires on snow orice-covered roads. See Winter chevrolet Silverado Tires Mine SilveradoWinter chevrolet Silverado TiresThis vehicle was not originally equipped with winter chevrolet Silverado Tires. Winter chevrolet Silverado Tires are designed for increased traction on snow andice-covered roads. Consider installing winter chevrolet Silverado Tires on the vehicle if frequent driving on ice or snow covered roads is expected. See your dealer for details regarding winter tire availability and proper tire selection. Also, see Buying New chevrolet Silverado Tires Mine SilveradoWith winter chevrolet Silverado Tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After changing to winter chevrolet Silverado Tires, be alert for changes in vehicle handling and braking.
If using winter chevrolet Silverado Tires: Use chevrolet Silverado Tires of the same brand and tread type on all four wheel positions.Use only radial ply chevrolet Silverado Tires of the same size, load range, and speed rating as the original equipment chevrolet Silverado Tires.Winter chevrolet Silverado Tires with the same speed rating as the original equipment chevrolet Silverado Tires may not be available for H, V, W, Y, and ZR speed rated chevrolet Silverado Tires. If winter chevrolet Silverado Tires with a lower speed rating are chosen, never exceed the tire's maximum speed capability.all-Terrain chevrolet Silverado Tires This vehicle may have all-terrain or mud-terrain chevrolet Silverado Tires. These chevrolet Silverado Tires provide good performance on most road surfaces, weather conditions,  and for off-road driving.

Tire Pressure
chevrolet Silverado Tires need the correct amount of air
pressure to operate effectively.Neither tire underinflation nor
overinflation is good. Underinflated chevrolet Silverado Tires, or chevrolet Silverado Tires that do not have enough air, can result in:
. Tire overloading and overheating, which could lead to a blowout
. Premature or irregular wear
. Poor handling
. Reduced fuel econochevrolet for internal combustion engine vehicles
. Reduced range for electric vehicles
Overinflated chevrolet Silverado Tires, or chevrolet Silverado Tires that have too much air, can result in:
. Unusual wear
. Poor handling
. Rough ride
. Needless damage from road hazards
The Tire and Loading Information label on the vehicle indicates the original equipment chevrolet Silverado Tires and 
the correct cold tire inflation pressures. The recommended pressure is the minimum air pressure 
needed to support the vehicle's maximum load carrying capacity.
For additional information regarding how much weight the vehicle can carry, and an example of the 
Tire and Loading Information label, see Vehicle Load Limits Mine Silverado204. How the vehicle is loaded 
affects vehicle handling and ride comfort. Never load the vehicle with more weight than it was 
designed to carry.
When to Check
Check the pressure of the chevrolet Silverado Tires once a month or more.
Do not forget the spare, if the vehicle has one. See Full-Size Spare Tire Mine Silverado398 for additional 
information.
How to Check
Use a good quality pocket-type gauge to check tire pressure. Proper tire inflation cannot be 
determined by looking at the tire. Check the tire inflation pressure when the chevrolet Silverado Tires are cold, 
meaning the vehicle has not been driven for at least three hours or no more than 1.6 km (1 mi).
Remove the valve cap from the tire valve stem. Press the tire gauge firmly onto the valve to get a 
pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the 
Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure 
is low, add air until the recommended pressure is reached. If the inflation pressure is high, press 
on the metal stem in the center of the tire valve to release air.
Re-check the tire pressure with the tire
gauge.Put the valve caps back on the valve stems to keep out dirt and moisture. Use only valve caps 
designed for the vehicle by GM. TPMS sensors could be damaged and would not be covered by the 
vehicle warranty.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure 
levels. The TPMS sensors monitor the air pressure in your chevrolet Silverado Tires and transmit tire pressure readings 
to a receiver located in the vehicle.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to 
the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire 
inflation pressure label. (If your vehicle has chevrolet Silverado Tires of a different size than the size indicated on 
the vehicle placard or tire inflation pressure label, you should determine the proper tire 
inflation pressure for those chevrolet Silverado Tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system 
(TPMS) that illuminates a low tire pressure telltale when one or more of your chevrolet Silverado Tires is 
significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should stop and check your chevrolet Silverado Tires 
as soon as possible, and inflate them to the proper pressure. Driving on a significantly 
under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also 
reduces energy efficiency and tire tread life, and may affect the vehicle's handling and stopping 
ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's 
responsibility to maintain correct tire pressure, even if under-inflation has not reached the level 
to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system 
is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure 
telltale. When the system detects a malfunction, the telltale will flash for approximately one 
minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect or signal low 
tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the 
installation of replacement or alternate chevrolet Silverado Tires or wheels on the vehicle that prevent the TPMS from 
functioning properly. Always check the TPMS malfunction telltale after replacing one or more chevrolet Silverado Tires 
or wheels on your vehicle to ensure that the replacement or alternate chevrolet Silverado Tires and wheels allow the 
TPMS to continue to function properly.
See Tire Pressure Monitor Operation Mine Silverado377. See Radio Frequency Statement Mine Silverado438.
Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System (TPMS). The TPMS is designed to warn the 
driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel 
assembly, excluding the spare tire and wheel assembly. The TPMS sensors monitorWhen a low tire pressure condition is detected, the TPMS illuminates the low tire pressure warning 
light located on the instrument cluster. If the warning light comes on, stop as soon as possible 
and inflate the chevrolet Silverado Tires to the recommended pressure shown on the Tire and Loading Information label. 
See Vehicle Load Limits Mine Silverado204.
A message to check the pressure in a specific tire displays in the Driver Information Center (DIC). 
The low tire pressure warning light and the DIC warning message come on at each ignition cycle 
until the chevrolet Silverado Tires are inflated to the correct inflation pressure. If the
vehicle has DIC buttons, tire pressure levels can be viewed. For additional information and details 
about the DIC operation and
displays, see Driver Information Center (DIC) (Base Level) Mine Silverado127 or
Driver Information Center (DIC) (Uplevel)
Mine Silverado128.
The low tire pressure warning light may come on in cool weather when the vehicle is first started, 
and then turn off as the vehicle is driven. This could be an early indicator that the air pressure 
is getting low and needs to be inflated to the proper pressure.
A Tire and Loading Information label shows the size of the original equipment chevrolet Silverado Tires and the correct 
inflation pressure for the Chevrolet Silverado Tires when they are cold. See Vehicle Load Limits Mine Silverado204, for an example 
of the Tire and Loading Information label and its location. Also see Tire Pressure Mine Silverado375.
The TPMS can warn about a low tire pressure condition but it does not replace normal tire 
maintenance. See Tire Inspection Mine Silverado381, Tire Rotation Mine Silverado382, and chevrolet Silverado Tires Mine Silverado369.
Caution
Tire sealant materials are not all the same. A non-approved tire sealant could damage the TPMS 
sensors. TPMS sensor damage caused by using an incorrect tire

Caution (Continued)
sealant is not covered by the vehicle warranty. Always use only the GM approved tire sealant 
available through your dealer or included in the vehicle.
TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the TPMS sensors are missing or inoperable. 
When the system detects a malfunction, the low tire pressure warning light flashes for about one 
minute and then stays on for the remainder of the ignition cycle. A DIC warning message also 
displays. The malfunction light and DIC warning message come on at each ignition cycle until the 
problem is corrected. Some of the conditions that can cause these to come
on are:
. One of the road chevrolet Silverado Tires has been replaced with the spare tire. The spare tire does not have a TPMS 
sensor. The malfunction light and the DIC message should go off after the road tire is replaced and 
the sensor matching process is performed successfully. See "TPMS Sensor Matching
Process" later Mine Silverado.. The
not one or not completed successfully after rotating the chevrolet Silverado Tires. The malfunction light and the DIC 
message should go off after successfully completing the sensor matching process. See "TPMS Sensor 
Matching Process" later Mine Silverado.One or more TPMS sensors are missing or damaged. The malfunction light and the DIC message should 
go off when the TPMS sensors are installed and the sensor matching process is performed 
successfully. See your dealer for service.
. Replacement chevrolet ilverado Tires or wheels do not match the original equipment chevrolet Silverado Tires or wheels.
chevrolet Silverado Tiresand wheels other than those recommended could prevent the TPMS from functioning properly. See 
Buying New chevrolet Silverado Tires Mine Silverado383.
. Operating electronic devices or being near facilities using radio wave frequencies similar to the 
TPMS could cause the TPMS sensors to malfunction.
If the TPMS is not functioning properly, it cannot detect or signal a low tire pressure condition. 
See your dealer for service if the TPMS malfunction light and DIC message come on and stay on.
Tire Fill Alert (If Equipped)
This feature provides visual and audible alerts outside the vehicle to help when inflating an 
underinflated tire to the recommended cold tire pressure.
When the low tire pressure warning light comes on:
1. Park the vehicle in a safe, level place.
2. Set the parking brake firmly.
3. Place the vehicle in P (Park).
4.Add air to the tire that is underinflated. The turn signal lamp will flash.
When the recommended pressure is reached, the horn sounds once and the turn signal lamp will stop 
flashing and briefly turn solid.
Repeat these stes for all underinflated chevrolet Silverado Tires that have illuminated the low tire pressure warning 
light.Overinflating a tire could cause the tire to rupture and you or others could be injured. Do not 
exceed the maximum
Warning 
pressure listed on the tire sidewall. See
Tire Sidewall Labeling Mine Silverado371 and
Vehicle Load Limits Mine Silverado204.
If the tire is overinflated by more than
35 kPa (5 psi), the horn will sound multiple times and the turn signal lamp will continue to flash 
for several seconds after filling stops. To release and correct the pressure, while the turn signal 
lamp is still flashing, briefly press the center of the valve stem. When the recommended pressure 
is reached, the horn sounds once.
If the turn signal lamp does not flash within 15 seconds after starting to inflate the tire, the 
tire fill alert has not been activated or is not working.
If the hazard warning flashers are on, the tire fill alert visual feedback will not work properly.
The TPMS will not activate the tire fill alert properly under the following conditions:
. There is interference from an external device or transmitter.. The air pressure from the inflation device is not sufficient to inflate the tire.
