2008 GMC 2500 Sierra - Change factory tire pressure setting

2 questions:

1. After rotating tires, how do I make the sensors learn their new positions?

2. How do I change the factory tire pressure on my 2008 GMC 2500 4WD Sierra truck? Currently set at 60 lbs front and 70 lbs rear. Seeing early life tire wear from too high pressues. Tires wearing bad in center. I know how to get max milage from a tire by rotating/balancing often, but GMC has decided not to let me adj tire pressure for my driving and towing needs! Need help before I put new tires on.

Instrument panel says check rt rear tire pressure. Yellow light on. Pressure fine. How do I reset? 2008 gmc 2500 he crew


The sensor is a part of the valve stem. It is a radio..powered by a battery. The battery may be dead, requiring a new sensor. Also possible that your tires have been rotated and the shop did not reprogram each sensor to the proper wheel position. Check your other tires first, then go to a shop that can test that all sensors are functioning properly.

My front wheel sensor shows low tire pressure, but it is fine. Is there a reset for that?


If its reading low and the tire pressure is correct there is a problem with that sensor. Typically they need to be replaced in order to correct the problem. A TPMS tool capable of displaying TPMS sensor data would confirm the bad reading.

They display the tire pressure as a convenience. They don't have to display the pressures and many makes/models do not.

The level of sophistication with these systems is slowly improving. Many newer models will automatically know where the tire is and display it correctly. Unfortunately yours need to be relearned manually after every tire rotation which is very common with earlier systems. It is assumed that this is done after every tire rotation which would then make the displayed tire locations correct.

If you are confident that the correct tire location is being displayed than I wouldn't see any issue with replacing that sensor. If you are not confident the correct tire location is being displayed than it wouldn't be a bad idea to do a relearn procedure.

The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Press and hold the Remote Keyless Entry (RKE)
transmitter's LOCK and UNLOCK buttons, at the
same time, for about five seconds to start the TPMS
learn mode. The horn sounds twice indicating the
TPMS receiver is ready and in learn mode.
4. Start with the driver side front tire. The driver side
front turn signal also comes on to indicate that
corner's sensor is ready to be learned.
5. Remove the valve cap from the tire's valve
stem. Activate the TPMS sensor by increasing
or decreasing the tire's air pressure for about
eight seconds. The horn chirp, can take up to
30 seconds to sound. It chirps one time and then
all the turn signals flash one time to confirm the
sensor identification code has been matched to
the tire/wheel position.
6. The passenger side front turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side front tire and
repeat the procedure in Step 5.
7. The passenger side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the passenger side rear tire and
repeat the procedure in Step 5.
8. The driver side rear turn signal comes on to
indicate that corner sensor is ready to be learned.
Proceed to the driver side rear tire, and repeat
the procedure in Step 5.
9. After hearing the single horn chirp for the driver
side rear tire, two additional horn chirps sound
to indicate the tire learning process is done.
Turn the ignition switch to LOCK/OFF.
If no tires are learned after entering the TPMS learn
mode, or if communication with the receiver stops, or
if the time limit has expired, turn the ignition switch to
LOCK/OFF and start over beginning with Step 2.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.

This info can also be found on page 5-66 of your owners manual.

Wheels were changed on my 2008 GMC Sierra 1500 pickup and I get a continuous light for the tire pressure monitor system.Won't reset so what is my problem and how can I fix it?


If just the tires were changed and you still have the original rims on the vehicle then you may just have a bad pressure sensor in on of the rims or the system may need to be reprogammed to recognize the sensors. If the RIMS were also changed then the replacement rims may not have the pressure sensors in them in which case the light will always be on since the system is always looking for pressure sensor signals that aren't there. If the rims were replaced and don't have the sensors you can purchase and install new sensors in these rims and program them so the system will recognize them.

Hi, this is indicating a low tire pressure issue. The first thing to do, is check all of the pressures, according to the list on the label of the driver door. I say check all, because, if you have had the wheels off, new tires, brakes, or rotations, the relearn may not have been done, and the tire positions, may not be as described. So check all pressures, and if 1 is low, this is the issue. If they are all good, and the light persists, you need to visit the dealer, as you may have a problem with a sensor. Good luck...Coop

How do i reset the tpms on a 08 implala SS after a tire rotation,without a owners manual


You have two minutes to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than two minutes, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions the matching process stops and you need to start over.
The TPMS sensor matching process is outlined below:
  1. Set the parking brake.
  2. Turn the ignition switch to ON/RUN with the engine off.
  3. Press the Remote Keyless Entry (RKE) transmitter's lock and unlock buttons at the same time for approximately five seconds. The horn sounds twice to signal the receiver is in relearn mode and TIRE LEARNING ACTIVE message displays on the DIC screen.
  4. Start with the driver side front tire.
  5. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for five seconds, or until a horn chirp sounds. The horn chirp, which may take up to 30 seconds to sound, confirms that the sensor identification code has been matched to this tire and wheel position.
  6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
  7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
  8. Proceed to the driver side rear tire, and repeat the procedure in Step 5. The horn sounds two times to indicate the sensor identification code has been matched to the driver side rear tire, and the TPMS sensor matching process is no longer active. The TIRE LEARNING ACTIVE message on the DIC display screen goes off.
  9. Turn the ignition switch to LOCK/OFF.
  10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label.
  11. Put the valve caps back on the valve stems.

Gmc sierra 2008 low tire pressure problem


You can follow this to reset it.
Ignition ON, initiate the TPM Learn Mode
using one of the following procedures:

  1. On vehicles equipped with keyless entry, simultaneously press the keyless entry transmitters lock and unlock buttons until a double horn chirp sounds indicating the Learn Mode has been enabled. The left front turn signal will also be illuminated.
  2. On vehicles not equipped with keyless entry, press and release the driver information center (DIC) INFO button until the TIRE LEARN message appears on the DIC display. Press and hold the SET/RESET button until a double horn chirp sounds indicating the Learn Mode has been enabled. The left front turn signal will also be illuminated.
  3. Increase/decrease the tire pressure for 8-10 seconds then wait for a horn chirp. The horn chirp may occur before or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached. Once the horn chirp has sounded, the sensor information is learned and the turn signal in the next location to be learned will illuminate.
    After the horn chirp has sounded and the right front turn signal is illuminated, repeat step 2 for the remaining 3 sensors in the following order:
    3.1. Right front

    3.2. Right rear

    3.3. Left rear

    When the left rear sensor has been learned and a double horn chirp has sounded, the learn process is complete and the RCDLR exits the learn mode.
    Ignition OFF, adjust all tires to the recommended pressures
