Check the label inside the drivers door for correct tire pressures. The most overlooked pressure check is on the spare tire.

| Post subject: | tire pressure monitor issues |
I tried searching with no luck. Has anyone had issues with their tire pressure monitoring system? The light comes on when it gets cold. (I know tire pressure changes when the temperature changes) I checked the tires and they are all set correctly and the dealer said the actual monitoring system is operating correctly but the light is still coming on. Are there any recalls or known issues relating to the system or any posibilities that they are overlooking? one thing that was confusing is I was told the correct pressure was supposed to be 27psi, but I thought it was supposed to be more like 33? I have the stock goodyears. Thanks in advance |

With my limited knowledge of them and my experience, my light was on when the temp had a drastic change the first time it snowed here in colorado, so I rechecked my air levels and got them back to spec. I cant rememebr if I went off the the tire or the sticker on the door, try both and see which one shuts off the light. Also I noticed driving it after it sits over nite can sometimes shut off light, either way its not that much air that will put the light on, have fun. I changed rims and tires and unlike Digger I didnt buy new TPMS units for the new set, so my light is on all the time

Correct pressure on my 2008 ltd (with the 18" wheels) is 33 PSI. I've had my low tire warning come up once due to the cold, but my tire pressure had dropped to somewhere around 25 i think. pump em up a bit (to 33lbs COLD tire pressure) - that should fix your problem. |

my door stickers says 33 PSI... You may have batteries that are failing. but that is hard to prove. unless theya re willing to put the TPM in a freezer over night... I run 40 my self, but I also watch for tire wear.. |

With the recent cold snap I'd pump up to 35 or 36 From the FSM The tire pressure will vary with temperature by about 1 psi (6.9 kPa) for every 12°F (6.5°C). This means that when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure (placard pressure). This is defined as the tire pressure after a vehicle has not been driven for more than 3 hours - and in outside ambient temperature. The tire pressure will also increase as the vehicle is driven - this is normal and there should be no adjustment for this increased pressure. For a system fault, the system will return to normal once the WCM receives a valid transmission from that sensor location |

Thanks for the info. I am going to double check the pressure and increase it to about 33 psi. |

I want to add that I had received training that once a tire has been driven 1 mile it can no longer be considered a COLD tire, granted do I remember where I got this training, no it was either Sears or Sam's Club worked in both shops |

Have I ever told you how much I hate the tpms. If you live in a cold climate get your tires filled with nitrogen and see how that works for you. Its more stable and doesn't react to temperature change as much. the temps in my hometown can change from well below freezing to pretty warm all in a couple hours and back again overnight and I have had no tpm trouble at all. So far this winter from -25c to +15c I see people everyday going nuts over this light, we fill with nitrogen and we don't have to talk about it anymore.... I say the nitro fill works. |
