I am wanting to change out my stock Rzr tires for tires that are all the same size. I have seen this on some rzr's but mostly on the 1000's. What do I need to know to switch all the tires to the same size? Do I need to do anything custom or change anything to make them work without any problems? I have a Rzr xp 900 basically stock. Suspension and everything is stock. Or can I just throw on some more narrow tires on the rear similar to the front tires and call it good?
