    I put nitto ridge grappler 33x12.5 r20 on my 2014 jeep wrangler. What do you think the tire pressure should be?

    Find a nice open area of asphalt, take some chalk and mark a thick line across the tread. Drive forward in a straight line and then check the chalk mark. If it is evenly "worn" then the pressure is correct, if the chalk line is worn more in the middle the pressure is too high, and if it is worn more on the outside the pressure is too low. Pressure could vary slightly depending on vehicle, what add-ons you have (additional weight distribution), etc. Pressures can vary front to rear.

    Welcome to the forum.
