I am currently having an issue with my 2016 Dodge Ram. All spring and summer my tire pressure was fine. Just recently since it got colder my tire pressure monitoring system says my tire pressure is between 30-32 on all my tires and tells me to fill them up to 39 PSI. The issue is when I hook my compressor up to the tires it shows 39 PSI. When I use a tire pressure gauge it says 39 PSI. I am going to call my dealer tomorrow but was wondering if anyone else has had similar issues. I pick up my 2018 Rockwood Roo 233s this Saturday and want to make sure I drive the 100 plus miles with the proper tire pressure.
