So far the best At tire I have used (it is a hybrid I think) is the Kelly TSR. I have used them on my old GMC and never got stuck, mud or snow. I used them this year on my 3500 Ram diesel. A buddy and I were hunting or I should say trying to get to where we wanted to hunt north of the Ft. Peck Reservoir. Bentonite mud. We got about 100 yards in when the pick-up just sank into the mud. Thought we were going to be digging but put it in reverse and they dug us out of there.
