I recently installed 38 inch tires on my 2024 GMC 2500. For some reason my dash is saying that I am low on psi on just the rear 2 tires. I have understood that the gmc rear tires need to have more psi or something like that. What can I set them at to get the code to go away? The tires are 38 15.50 r20 Mud Grapps
