I am planning a trip flying to Salt Lake City Utah to hit Alta and snowbird. Then I am planing to drive to jacksonhole and back before flying out of Salt Lake City. My question is are there any sort of vehicle traction requirements and if there are, are they the same as I70 in Colorado. I have flown to Denver many times and have always been ok renting a sedan with M/S tires when going to vail/aspen/breck ect. Would I need to rent any different type of vehicle or insure it had any special tires?
