I'm looking to upgrade my stock wheel set on my new 2013 Sportsman 800. The stock wheels are 25"/10w/12" rear and 25"/8w/12" front (I believe). Looking at different wheel packages I'm not sure if I can go with a 14" wheel? or stick to 12" wheel? Basically what I'm asking is for any help? What sizes can I go up to without doing much other than swapping out the wheels. I like the Polaris Wrec and Sixr and for tires I like the looks of the Ripsaws, Maxxis Bighorn 2.0 and ProComp Extreme. Any help or advice is greatly appreciated. Thanks
