They're yokohama geolander mud terrains. We haven't had a lot of snow here this winter (abnormally low), but what we have gotten has been handled with ease. Also handles mud just fine too. I will say though, they are very aggressive, so that translates to a lower mpg and quite a bit of road noise. Neither really bother me since I don't drive it daily. I live in a pretty rural area and I have other vehicles so it may impact others differently. If I had a long daily commute on the interstate, I wouldn't go nearly as aggressive.
