I drove a fair distance in the cold and snow, then ended up parking in a bit of a drift. Snow melted on to the wheel. The vehicle almost bounced out of my hands when I drove above 50mph. I took it in to the local Fountain Tire for a check. My very reliable friend put it on the hoist to show me the frozen ice on the rim. He suggested the fancy rims are shaped in such a way that snow will get in and knock the tires out of balance. I now have a long ice scraper that I use to clear away the ice when it happens. (twice now). I guess this is an unwelcome side effect of the large tires and chrome rims.
But, still a very nice handling vehicle on the ice.
