Funny, I reached out to Mavic and asked about using other tire brands and types on their "UST" rims. They said that while other tires could be used, they don't recommend it. Based on that I passed on the wheels. The tires are made by Hutchinson and are good tires, at least. But I doubt they'll give you the same trouble-free service as the GP 4 Seasons, which are my "winter" tires. I've never flatted one, which is why I ride them when I ride in the cold and dark.
