tracks would be a lot more functional than tires I think in snow. Also steering appears to be less than ideal. I bet that doesnt even work in 3+ inches of snow.
Back in the fifties a buddy took a bob sled, put a Briggs motor at back of sled and one tire in a framework and drove all over the hard pack snow streets in town. Before there were any Polaris snow sleds around and it worked just fine. db
