I just bought a new sportsman 570 and want to replace the stock tires. It has 25 inch tires on 12 inch rims. I just wanted to get some opinions on what to get and what size, I am planning on running the new tires on the stock rims. I would like to go bigger than the 25 inch stock tires, but I do not want to have to put in a clutch kit. Any input would be much appreciated.
