Winter/Summer Tire Pressure
 
My tires had all been at 36 but I got a warning that the tire pressure was low (around 30-32). I figured this was because it got colder outside. I had been planning to put some air in the tires but then a week later it warmed up at they were back up to 35 with no warning.

And then it got cold again and I got the warning.

How do you handle tire pressure with the fluctuating temps right now?

You might want to have your tires filled with nitrogen instead of air. The tire pressure won't change so much with temperature fluctuations.

I did this with another vehicle that had a tire pressure monitoring system with no problems but you probably would want to confirm that it's ok with the Jeep TPMS first.

Nitrogen is Inherit, it will not cause any issues with anything.

where does one get there tires filled with nitrogen and how much does it cost?

You shouldn't have to change to nitrogen.

then what is the deal with the tire pressure changing depending on the temperature and what do i do until it gets to be fully winter?

About $5-$10 a tire depending on where you go.

You can enter in your zip on this page to find some local places that do Nitrogen: Get Nitrogen

I had heard a couple times in past that Costco would fill members tires with Nitrogen for free; didn't matter where the tires were from. Don't know if they still do that.

I wouldn't worry about it. Have you worried about it with past vehicles?

Even in the Summer, the tire pressure will be wildly different: say, in the morning when you leave your garage, versus driving for an hour in the sun, on baking hot summer asphalt.

Heat makes things expand, and cold makes them contract. It affects air molecules the same way. Nitrogen would stabilize the up and down swings. Usually I add regular air on the cool days, then leave it alone unless the temperature really spikes up to the mid summer range.

If it's warm fill them all up to 40 or 41. That's what I did. The coldest day since then and they were all at 37.

I agree.

I do add air when the weather starts to get cold to bring it to spec, and when summer hits drop it back as the heat makes it rise. A little fluctuation is normal. If I leave my car on my blacktop driveway, the side facing the sun will be a couple of pounds higher than the side in the shade.

Your vehicle needs to sit undriven for a few hours, out of direct sunlight, to obtain the cold pressure reading. I suspect this is the issue the OP is having. Even with seasonal changes in temperature, you should be fine with checking your tires every two weeks.


Paying for Nitrogen is a waste of money for passenger tire use.

Here is a pretty decent article (even though there are number of minor mistakes and ommisions): POWERTANK - CO2 Air Systems Here are a few additional points:
-Tthe air we breathe is approximately 78% nitrogen and 21% oxygen. (The article incorrectly states 17% oxygen).
- The effect of water vapour in tires is insignificant for passenger tire use.
