Have a stock 2013 Sportsman 500 HO with factory rims, factory Carlisle AT489 25x8.00-12 front tires, and factory Carlisle AT489 25x10.00-12 rears. Going to get some ITP SS212 machined 12" (12-7) rims and move the current tires to the new rims telling dealer I need the bolt pattern for ATV. When the Carlisles wear out, I only have 500-600 miles on them, upgrade to 26" Maxxis Bighorn 2's in 26-9R-12 front and 26-11R-12 on rear. Is this a clean upgrade without the need for spacers, lift kits, etc? This tire/wheel upgrade stuff is a science on its own, harder than buying the machine Thanks for advice.
