    Low tire presuure warning

    Has anybody else experience this problem. Last week we had our first true cold spell, morning temps in the low 20's. This generated a "Low tire pressure" warning indicator and message. Checked tire pressure; front = 32 psi and rear = 33 psi, tires call for cold tire reading of 33 psi. This lasted 3 days until the temp went to the 40's. Made a service appointment for 1/14/12 for this issue and have tires rotated. Tires were rotated and was told nothing wrong with the TMS, the warning light and message went away. Sunday morning, temp was low 20's and guess what, both light and message back, same as this morning.
    If this was posted in another forum I do apologize. I did a forum search and could not locate anything that deals with low tire pressure. Thanks

    I just had this problem myself, too. It came on two days ago, went off by itself this morning on the way to work.

    As long as your pressure is okay, I wouldn't worry about it. It's annoying as crap to have that message on the screen, but nothing bad has ever happened to me driving with it on.

    The only time I've had an issue is when I lowered my pressure in the front to 30psi to make the ride softer in the front. TPMS didn't like my idea and argued with me. Otherwise I've been seeing regular sub-zero temps here and have had no problems.

    It is very typical to see the TPMS light come on when the weather is cold early in the morning. This is why several folks use Nitrogen in their tires as it is less prone to temperature differences and keeps the TPMS in check.

    As Munky stated above, it will usually go out as you drive and the tire temp heats up.

    Put in 40 psi---end of problem. Handles better and increases mpg. No more warning light unless you pick up a nail.

    40 is a bit of pushing it, don't ya think? Imagine the ride quality on that? Plus when you drive for a while, wouldn't it reach 45-50 psi? There is no reason to overkill, unless you were joking.

    Thanks for all the great replies. If the indicators did go off after driving the car for awhile than fine. The problem is that regardless of how far I drive the indicators stay on and that 1) is not normal and 2) not acceptable. It appears that my only option is to inconvenience myself and bring it back. Oh well all part of owning a car.

    Check your tire pressures with a decent gauge when it is cold, adjust the pressures and forget about them for a month.

    Do you have Nitrogen in the tires? It would be indicated by the green valve caps instead of black. I have an SX and when the TPMS message came on a couple different times, I ran by the service department on the way home from work. They put air in and it went away for a couple of weeks. Happened a third time the other day so I went by again, and this time I went with the Tech, because even though I kept telling them to make sure they were putting in Nitrogen, it turns out they weren't. The Nitrogen tank was 3 service doors down from where they were putting in air. The Tech completely vented the tires and refilled with Nitrogen. Much better ride, I would not have believed the difference.

    Additionally, Nitrogen is supposed to have less pressure fluctuation based on temperature swings.

    I think the max psi our tires can handle (if we're talking about Nexens) is 50psi; but even then I'm with you, I wouldn't want to stretch that tire to it's maximum capability..
