Yeah a Toyota had to winch up maybe but I have a Jeep! :-P
Jeep probably has more weight in the back (oh wait, I can touch the back from the front if I lay down).
I had gone tire shopping and found some kevlar ones that a couple of the tire guys had on their Jeeps and swore by them. Said they would do everything but ice and nothing really helped on just plain ice but studs or chains.
