tire psi

good morning, I just switched from a tt to a 5th wheel and I noticed when hooked up my tires look a little low. Should I set the psi to what the tire says or what's on the door?

    Before you add propane, water, gear, hitch and PEOPLE......you only have 300 pounds of capacity left.
  • Get your rig weighed as it will be used and then check the load inflation chart from the tire manufacturer and inflate accordingly.

    :C
  • Thanks so much for the info, yes we are at the limit for the truck I did put Monroe load assist shocks on the rear and that did help. the pin weight is 1400lb but that's not loaded. I will look at the tires for the numbers when I get home but I do know its a Michelin LT tire.
  • Wow, if that FW is hooked up to your F150 and using a heavy Superglide slider, you will need the max tire pressure on the sidewall! What is your RAWR/tire max rating?

    That is a nice looking rig, but certainly at truck's limit.

    I would add a few lbs to front tires also, even though most all FW weight is carried by the rear.

    But what if the tires is not factory? Did some put lighter on it at some point- maybe heavier ply tires.

  • To what the tire says. Also make sure there rated for the weight your put on them. White the 5er in your sig I would say your put around 1500 to 1600lb in the bed.
