Yep. I ran a Camaro years ago that only needed 300# over the drive axle: I used sandbags. My stovebolt needs more than that. Slow..Rider has the best idea in his sand tubes, but a bag is nice, too, because on that one time you do need it, a little sand under the tires is as good as chains, and cheaper. Bigmacdaddy is also right. Those great big tires are useful in sand or soft mud, but otherwise pretty much decorative. In snow, ice or rocky ground they render a good truck completely helpless. Sometimes on warm ice, like in spring, a man can actually push a truck with those tires sideways on flat ground with all its wheels locked. The best tires for snow, hands down, are tactical tread. Narrow, high-profile military tires. Second best - and easier to live with - is a full set of high, narrow M&S radials with an aggressive (lumpy) tread pattern. In soft snow, with a little weight, you can drop the drive tire pressures to distribute the weight and lengthen the contact patch and she'll pull like a bulldozer.
