Just buy a decent A/T tire...it'll give u good all round performance for all season. Some have more square shoulders than others (I have Toyo's on my Tundra), just go to the local tire shop and look at the various ones to get the profile u want. A/T will be quieter in summer, but get u around just fine in most winter conditions...some are a little weak in the wet...
