Welcome to the forum!!! 
So your trying to decide what tire to get? The nitto's arent to bad. I plow in the winter time for a friend of mine and he actually just gets cheap tires because no matter what they where out quick! If you want something to look decent you might want to get a set of wheels for the summer and use your stockers and cheap tires for the winter. If I where you Id stick with the 265's though. My buddy had 285's onone of there plow trucks and it rubbed like crazy with the plow up. IIRC the plow was a meyers max.
