Aside from the obvious need for some extra clearance (usually 1-2 tenths of a inch) because of the studs (compared to similarly sized non studded tires) I've found it helpful to occasionally spray the inside of the fenders with WD40 which seems to help prevent snow/ice build up and keeps the surface cleaner. Dirty slush can be bad news as it dries to a hard lumpy surface that additional ice wants to stick to and builds up causing clearance problems.
