mm3846 I certainly wish I would have had some. I went to the neighbor's trailer and asked them if they had anything I could use. They had stump ends of 2x8 planks about the size of the Maxtrax. I used my hands to dig out the mud at the base of the tires and wedged the wood under but that didn't do the trick. Also, talking to the tow guys I mentioned that option (Maxtrax) and they were of the opinion that it wouldn't have been enough. As they were pulling me out (in neutral), I could feel the mud clinging to the tires and undercarriage. It was like having a rubber boot stuck in the mud and trying to lift your leg up and out.
I was in the vehicle when they hooked up and pulled me out. It was just slogging through the mud tracks. It wasn't just the tires, but the muddy ground making contact with the undercarriage. I really believe the only way I was going to get out of there was being pulled out by a cable or chain.
hickersb, they are Goodyear Wrangler Duratrac 19" (They came with the vehicle). The tread seems pretty aggressive and reasonably fresh. The problem is that once they got coated in that mud, it was game over. I wouldn't be surprised if I were to go there in the middle of the summer once things had dried out and firmed up that I could drive that same path without any problems. (Not that I am going back there. Lesson learned.)
I went in with the rig in with the frame lifted to off-road and in low-range with the mud and rut special program. I wasn't going fast, just testing it out to see how it would respond. Maybe that wasn't the way to best approach those conditions, but in all honesty I had no business being out there to begin with (especially on my own).
