Indeed, I am in Central Florida and light seems to come on whenever there is a 20+ degree drop in temperature overnight -- which is rarely. When it warms up the light usually goes off by mid-day.

A friend of mine has a new Chrysler Town & Country minivan and he said the tires are nitrogen filled. He says he thinks it rides a little better (recovers from bumps quicker) and the tire pressures are always the same cold or hot. Doesn't nitrogen expand?

LOL-
 
I agree with SHIPO - I have heard the same wonderful things about Nitrogen its power to increase gas mileage. However, I only let the dealership touch my ride... so whatever is in those tires -- air, nitrogen, bad breath or methane; I still see the tire pressure light come on whenever there is 20 degree change in temperature here in Orlando.

What does your pressure sensor read for each tire at normal morning temperatures for you? Check with a dial type pressure guage at each valve (I found that the slide type I was using was inaccurate and I was not filling the tires to the correct pressure: too low so that my warning light was also coming on in cool mornings). Once I got the right pressure in, no more lights in the morning!

I also carry a dial type pressure guage in my glove box and threw away all my junk slide types. Cold inflation pressure is exactly 34 psig at all four corners. Normal (hot) driving brings the pressure up to 38 to 40 psig according to the sensors. When I recheck the pressures with the dial guage the sensors proved to be accurate. I get a low pressure alarm from the sensors at any pressure below 30 psig. The tires I am using are Michelin Latitude P255R55-18 and the normal recommended inflation pressure is 30 psig, with a max load pressure limit of 44 psig. The tires are run flat design, so they already feel a little on the firm side at low pressure. They are very good tires and I strongly recommend them to anyone considering a good replacement for the OEM supplied Continentals.

You are correct. This air vs. nitrogen controversy has been going on for a long time now. I have heard that the Indy and Nascar race teams have been using nitrogen for a long time. I also heard that the Corvette comes from the factory with nitrogen filled tires. Gas expands and contracts with temperature changes and the pressure changes. Why nitrogen? I really don't know. Why not helium? (maybe your mileage would increase! LOL!

Exactly. I'm surprised we haven't been mandated to fill our tires up with Ozone so as to protect the earth from global this or that!
