I have a 2013 850 XP HO and I've read a lot about people getting the wrong offset and the wheel and tire sticking way out (mainly in the rear). I don't want to make the same mistake, so I wondered if anyone knew what the proper offset would be. I'm thinking of getting the MotoSport Alloy M20 Kore, they have a +0mm offset, I'm just not exactly sure what that means. I'm thinking of getting a set of 27" Interco Reptile Radial tires mounted on them as well. Any help would be great!
