Kevin Biggerstaff he never said tires have nothing to do with it re read his comment before being a prick. He said when the truck weighs to much it doesn’t matter what tires you have. Put big mud tires on a bus won’t matter for shit
SonBurst i think its the Denali. Denalis come with an AWD system controlled by the trucks computer. With 4wd (which is what I have and recommend) you can select what tires spin. In mud like this you want front send rear lockers so all 4 wheels spin at the same time.
Tire pressure has alot to do with being stuck in mud also. Deflate your tires to about 25 to 30 psi and put little weight in the tray so the back won't be too light
