Hello everyone, a noob grizzly owner. Just picked up a 2013 700 eps and would like to upgrade the tires over stock. It has maxxis mu19/mu20's on it now, 25-8x12 and 25-10x12's. What size tire can I go to with the stock wheels and not have to get into shimming, springs, etc...I see a lot of mud and will be plowing snow as well. Any suggestions would be appreciated. Thank you.
