how mush psi do i put in my bigger tires

[JB.]

i have 285/75/16 tires and i was wondering what tire pressure is best for good mpg and handling . right now i am running 25 psi on all 4 tires. is that too low?

The sizing info (285/75/16) is incomplete without including the P or LT in front of it.

1. Look at the door sticker and get the stock tire size and psi. 2. Go to the link and look at the referenced load/inflation pdf. 3. Find the stock tire size (including the P or LT) and see how much load capacity it has at the door sticker pressure. 4. Find the tire you're using and figure out how much pressure it would need to have a similar load capacity.

............or you could just put in 35psi..........
