tire pressure question
Just put Michelen lt tires on my 2013 f150 4x4 cc. Max pressure is 80 psi. E rated. My question is what would be a good pressure to run when not towing or hauling? What do you folks do? Door jam...

"E" tires on a 1/2 ton are NOT a mistake! You need to inflater them properly for the load. Sidewall stability when towing a TT can save your life!
Agree^.
Then you have the ultimate ability to change pressure based on load and preference.
To the above poster, of course you needed to lower them to 30ish psi on a lighter vehicle. No different than your c rated tires. It stands to reason that with a stiffer sidewall, the heavier tires carry a "little" weight in the sidewalls so expect to run a few psi less than C tires for the same ride.
Remember, the tires do not support the load, the air does. Tires are a containment vessel for the air that also provide traction.
If you have a flat on a 1/2 ton with an E load tire, the truck will squish the tire just as flat as a C tire.
Also remember, up to E load and some of the new "fake" light duty F load rated tires, they are designed to run at lower pressures unlike med duty tires (19.5s) which should maintain a higher minimum pressure to not destroy the carcass and prevent losing the bead seat.
