What tire pressure should I run these tires at for pulling. They are both 6 ply. One is a Firestone F151 and the other one is a Titan power king. They have about 95% tread.

In hard tracks you need 10 lbs or so and in loose, sandy, tracks maybe 6 to 8lbs. The lower the pressure the more the lugs want to turn under and the lower the drawbar gets.
