What does everyone run for psi in their terra grapps. Im runnin p285/70/17s @35psi didnt know if I should bump it up

Also I was under the impression they should be around 32.74in tall
Mine are under 32in tall. Is that due to not having enough psi?

max air pressure of those tires is 35 so that should be a good psi to run them at.

nitto's website shows that the tire measures 32.72" tall by 11.46" wide mounted on a 17x8.5 wheel. your rim width and tire wear can make a slight difference as well as your vehicle sitting on the tire. these measurements are taken when there is no weight on the tire and when the tire is brand new.

air pressure is not going to make a difference in tire height. it can make a difference in overall height of the truck. but i suggest running the recommended air pressure for your vehicle and tire (35psi). never exceed the maximum air pressure on the side of the tire. check the sticker on the door for recommended air pressure unless running a different tire that came from the factory
