you should drive a samurai with 31's on the snow, when I first got mine I was following snowmobiles up in the hill's, when I stopped to get out by an intersection on the dirt logging road there was a sign sticking up out of the snow about six inches! so I guess there was six to seven feet under me, I had no problems at all. all stock with a spoa and a fiberglass hard top on it. prob. 2300 lbs. on bfg allterrains with 20 lbs air.
