Hey all, new to the diesel scene. Have an 04 gmc duramax crew. Just made it into deer camp but had a hell of a time on the two rut road. Wet grass covered with wet clay underneath. My truck got stuck a few times. I have masterforce courser ltr tires, and found out at camp they have 75 psi each. What can i do to help make sure i can get out of here without getting this hog stuck? Can i go down alot in psi for my tires? Will that help much? Thanks
