@mitch I don't think that'll be their problem. The trick is that salt corrosion occurs extremely slowly at the temperatures where we need road salt, so if you have a long prairie winter with very little time spent above zero, you can ignore it until spring. Then you just wash it well come springtime, and the CT might actually be better in that regard if it's smoother and there's less salt residue hidden in nooks and crannies that escapes the washing process.

I expect the bigger issue will be the weight of the thing; it's three tonnes and they had to make the tire pressure stupid high to bear the load. So it will have a much greater shear loading on its contact patches (easier to break free on ice) and somewhat worse flotation (sinks in deeper in snow).
