Tire Pressure sensor

I just installed 22 inch rims and tires on my 08 regular cab Silverado 4x4.

The tire sensor symbol on my dash stays lit up, with a message occasionally saying service tire sensors. I had new sensors put in each tire, so why do I keep getting this message. Do I need to reset the computer somehow..
Thanks

bye

I would take it back, if you just sank like 1700 bux in wheels they should make sure your light stays off. They prob need reset.

Do the 22'' Rim's + tires hold the same air pressure as standard tires?
The computer wants to see a certain psi!

just because the profile is different it still takes the same pressure to hold up the truck.

Its sounds as either one of the tire monitoring sensors was damaged or the tire monitoring system was not calibrated correctly after install.

I pulled this directly from Alldata on what should have been done, run it by your installer and see what they say. Also, not sure if it applies, but make sure the 22" rims you bought are able to run the tire monitoring system correctly. But like I said, more then likely you need correct recalibration.

Tire Monitoring System: Technical Service Bulletins
Reprogramming (RCDLR) For Proper Tire Inflation Pressure
Reprogramming Remote Control Door Lock Receiver (RCDLR) for Proper Tire Inflation Pressure

When GM Accessory wheels and tires are installed on a vehicle that requires a different tire inflation pressure according to the Tire Inflation Placard the RCDLR must be reprogrammed with the new pressure and tire type (P or LT). If this is not done the vehicle will incorrectly report or high tire pressure conditions incorrectly. Follow the steps listed below to select the appropriate tire type/pressure:

1. Install the scan tool.
2. Turn ignition ON with the engine OFF.
3. Enter "Diagnostics" and build the vehicle according to model year, vehicle line, etc.
4. Select: "Body".
5. Select "RCDLR Module".
6. Select: "Module Setup".
7. Select: "Tire Type/Pressure Selection".
8. Select P-Metric Standard.
9. Select the front and rear tire pressure as noted on the new vehicle driver door placard sticker for the accessory wheels/tires.
10. Verify that the selections made are correct and press the enter key. The scan tool will flash "Procedure in Progress" then display "Procedure Complete".
11. Press the "exit" key to escape.

Other Electronic Module Reprogramming;

For proper vehicle operation and to ensure coverage under the provisions of the new vehicle warranty, the vehicle may require that certain modules be reprogrammed with the correct calibrations as soon as the GM Accessory wheels and tires are installed. Examples of the modules may be affected are Electronic Brake Control Module (for proper anti-lock brake and stability control performance) and Engine Control Module (for proper speedometer/odometer function).

Please see the Corporate Bulletin specific to the vehicle and wheel/tire application for detailed information on module reprogramming.
