28″ on 850 touring?

I own a 2014 sportsman 850 touring. She’s stock hight and I want to install 28" maxxis zillas on the stock 14" rims. I’m wondering if anyone can give me advice on any clearance issues. On maxxis Web sight the 28" Zillas are less than an inch taller than the 26" bighorns that by buddy has on his 850HO. Any help would be great.
