tire pressure

[Lamoo12]

I will be taking our travel trailer on a trip next week, first time! Rumor has it I am supposed to adjust the tire pressure on my Expedition. How do i know what the PSI should be? What do you all set it to? TIA

its going to depend on what tires you have... if you p rated tires or light truck 6 ply tires i would max the pressure which will be somewhere between 32 & 50 psi if your running 8 or 10 ply 50-60 psi will be plenty also max your trailer tires our for a more enjoyable towing trip
