Has anyone else had handling issues with snow? I was disappointed in my Passport's (AWD Touring with OEM wheels and tires) handling during our first major snowfall (6") here in NE Kansas. The Passport unexpectedly slid out several times despite slow (<25 mph) speeds, flat roads, and gentle braking. One time I banged the curb hard and one rim now has a large scrape along 1/3 the rim's radius. I am now researching (mainly reviewing previous Passport Forum threads) to either buy winter tires and/or buy 18" rims plus winter to get better winter handling (and more rubber and hopefully less rim scrapes). Has shifting to small diameter rims (18" or 17") helped? Overall, I love the Passport. Appreciate any advice.
