quading involves all type off terrian. depending on the type of terrian you will be most encountering. if you are doing lots of snow riding you should by a wider tire than a tall one. mud riding requires more of a tire with a tall profile and deep lugs atleast 2 inches or more.howevr if you put a really agressive mudding tire on you might feel vibration on a hard pact trail.in that case you probably want to by more of a trail tire whick is smooth and softer with not to much of a lugg. but if you are riding in dunes you will want a paddle tire.
