Fellow Jeepers, how often do you all check for tire pressure and fill air if necessary? I have13 JKU with 315/70r17 Duratrac!s and was set to 30psi when I installed a month ago. Now my tpms warning came on indicating 24 psi on right rear and left front (rest are 25psi) after I parked outside all evening at 35F (it's Michigan). I know cold temp tend to drop the air pressure but just one day of parking outside? Or do you guys think I have a slow leak? Any insight and advice would be great. Thanks

 

Yes the temps do make the pressure fluctuate, I check my pressure once a month on avg.

 

My buddy checks his every week I do it once a month also but I don't drive my jeep to much!

Jeepin on a budget

 

Every two weeks or when the weather conditions and temperature changes. 75k on my toyo mt now.

 

Don't panic. Just pump them up as required. If you have to do it all the time(once a week) and they drop 5 psi each time and it's not able to be blamed on the weather then get them checked.

As a side note:
Bigger tyres will show more difference in pressure because of the higher volume of air inside the tyre.

That's my 2 cents. I hope it helps a bit.

 

I too check the tires about once a month. Make sure you are using an accurate gauge and use the same gauge each time. Tires will lose about one pound per month but temperature changes will also cause a change in your tire pressure.

 

I need to start checking them more often. Noticed my MPGs were staying around 10MPG when I normally am around 15 with my 37s. So I checked today and they were at 18

Have no idea how they got so low... But I havent checked since my last wheeling trip. about a month ago.


I would say try to check them every other month or so.

 

Tires will drop psi over night with cold temps. Just check them when weather starts to cool off

 

Thanks all! Let me air it back today and check back in a couple of days.

 

I would say I check the dash PSI about every week to make sure things are good.
