i could see throwing some in the rig if you are driving a front wheel drive honda or mini van, I have seen plenty of them not be able to get started on hoosier or vail if they have to stop on an icy night, they just sit there and spin the tires until they smoke, or a rear wheel sedan or van maybe,
a decent 4x4 with quality tires shouldn't have any issues, you have to stir the transfer case of course, it's a $3000 dollar option for a reason.
