TPMS Dash Reading

[DadsDodge]

My 2011 Laramie started a weird one over the weekend. When I start the truck the rear right tire reads low on the dash and the tire light is on. After driving a few miles that tire will go back to a normal reading but the front right will read low. The next trip it may do the same thing but on the left side. One tire is always reading low but it's never the same one. Thanks for any help, I don't even know where to start.

If your TPMS sensors are the 2011 originals, I would bet the batteries are going out.
