You folks with lifted Expys and off road tires, what are you running for air pressure?
I have found 45 lbs to be the best for my 33” E load tires.
This is for on road driving of course.
Off road for what I do 30lbs seemed pretty good but have not tried anything else.
should you run a higher tire pressure because you have a lifted vehicle?
If you have larger tires with a higher load rating most likely so.
Simply lifting the truck, no.
Probably should’ve asked this a different way....
For those of you who are running larger wheels and tires than factory, ie off road / all terrain, what tire pressure are you operating with?
I run 55psi in my LT275/65r18 Duratracs. I know they’re not bigger than stock but mine came with the 275/55r20s.
I have 35x12.50x20’s with a load range E rating. They require 65 PSI to have the maximum weight rating of 3195 lbs. I run 45 PSI and have no problem with wear or towing. At 65 they are pretty stiff and crown a little.

Thanks for all the replies. I’ve got a bit of vibration after the 3/2 lift and new tires that I’m trying to figure out. I’ll drop them down to 45 to see if that helps. If not, they go back on the Road Force balancer!
