Temperature changes and cold weather in particular, along with ordinary driving can impact your vehicle's tire pressure.
In the below video, Chrysler Group gives an overview of how those changes impact tire pressure, and how to use your vehicle's systems to ensure you're driving with optimal tire pressure -- which helps your fuel economy. A Ram truck is used an example but the tips can apply to all Chrysler Group vehicles: Ram, Jeep, Chrysler, Dodge.
At the end of the video is a particular note if you have a Ram 2500 Heavy Duty.
