Is anyone running 33" pro comp xterrains? If so what pressure are you running them? It says 35PSI on the side but I have them at 24PSI is that good?

That sidewall marking is MAX PSI...not the recomended PSI.

ALLLLLLLL tires are like that.

I would say 25 ish seems about right.

i don't know if i have ever gone by the sidewall's recommendation.

draw a chalk line perpendicular across the tire, drive in a straight line and see how it wares off. Add or remove air as necessary.

I run my 37" pro comp xt's at 7-15lbs depending on terrain.

it might help to know what vehicle they are on. but 25 is common
