I just took my studded and siped tires off for the Utah/Colorado/Arizona trip. I put Bfg KOs' on. Question is,.. winter is now back up here ,and I was wondering how the roads are down there. I don't want to have to put chains on as fender clearance is an issue with 32" tires. Driving in the snow and ice is no problem but how often do they require chains down there?
