Im looking to buy new tires for my 2013 Polaris Sportsman 500 H.O. The stock tires are; front - 25 X 8-12 / rear - 25 X 11-12. Im thinking about going with ITP Mudlites and ITP SS Rims , sizes; front - 27 X 10-12 / rear - 27 X 12-12. Would those fit without needing spacers or a lift kit? Also with these tires would you recommend a clutch kit? Thanks
