Tire OVERPRRESSURE Warning on Chevy 250 Silverado

The TPMS relearn process on the NBS Silverado's was actually a PIA for the first few years. There is actually a TSB on the relearn process because the air leaving the valve stem was causing irregluar vibrations that interfered with the sensor's transmitter (or something to the effect) . I did the relearn process on my 2007.5 1500 but I had to let the air out of the tire for 4-5 seconds almost exactly; if you let the air out until the horn honks (as indicated in the manual) you will have a flat tire before you ever hear the horn.

The oil change reminder reset is thru the DIC...pretty simple.

The tires have been this way for about 3000 or so miles. I will just have them rotated again which should restore things.
I really need to learn to reset the pressure sensors and the oil change light as well. So much for dealer support, they failed to reset them when these tasks were last accomplished. We too far down the road when I noticed.
I have been procrastinating. It seems that I am on a perpetual learning binge, trying to keep up. I thought that after retirement things would ease up some. What a laugh. At least before retired I got paid (ha ha - meaning I kept my job) for learning. Now its on me. Windows 8, 3 versions of android, 3 different types of phones and this is even before whine about to our "electronic" car with the security and sound systems that are dammed near incomprehensible. The dammed thing even wants to talk (connect) to my phone

Let air out if you prefer but I would set alarm a bit higher traveling under those conditions.

I don't believe there is a way to set alarms at different temps and psi.

I have never had a high pressure warning on my 2010 GMC with stock TPMS. They only read to 99 psi on the dash. I have had one or two loose signal and then get a warning. It usually resets after I stop, then start the truck back up it resets.

When you rotate the tires on a Chev with pressure sensors the sensors stay with the tire/wheel. You then go into the owners manual and use the procedure to "Relearn" each position. This is done on the dash board by selecting "Relearn" and then follow the directions from the manual. just a hint before you start remove all valve caps and have an air supply hose that will reach all tire, then start the procedure and don't hesitate too long between tires. I think you start with the left front but not sure, but it is all in the owners manual if you read it. Good luck

There should be a method to reset the sensors to the desired pressure. ON my Ford it involves some horn honking and button pushing but not too bad a job really.

I would also relearn the sensors. Also, don't let air out. It is increasing the pressure as the tire and rubber get hot. It is preventing damage from heat. There is nothing wrong with the pressures you mentioned under the conditions you described.

If tire pressures were filled when cold it's normal for psi to rise when riding in hot weather, engineers take this phenomenon into account when setting max psi for a tire. Let air out if you prefer but I would set alarm a bit higher traveling under those conditions.

Rather than move the sensors around, just reset the system when you change front & rear tire pressures.
