Well, I know my LX25's will restrain my CX5 going down a 27% grade in snow, but that is literally right on the limit with them 3/4 worn out. I might could do 30% grade with them during the first 1/4 of their life. Is Loveland steeper than that? If it's over 20% grade, I would not try it. Under 20% grade? I'd drive that any day unless it was ice, or the snow was so deep I was plowing it with the FMIC.Loveland Pass. You can come try after snow storm, and you might go up. Problem is going down as you need something that brakes well in those conditions, as 2,000ft cliffs do not look inviting.
IDK how Mazda would perform. Rarely seen there.
