I run mine at 40 in the front and 38 in the rear.. If pulling anything run the rear at 40 also.. Offroad on rocks and mud.. I run at 20... Sand run at 16.. You can go down to 12 in the sand, but I have not went lower than 16.. Come check out Club Hummer Offroad... Its more for the offroad fellas such as myself.. Make sure you introduce yourself and post a pic... By the way, nice rig and tires...

I am Pappibri on there as well... Also on H40
