Ive got 25-x-12 tires on it now, they look original and are dry rotting. Are the rear rims the same width? Id like to run 27-9-12 kenda bearclaws front and rear. I know the fronts are usually skinny and wider rears but most of the guys around here are running tall skinny's on all 4. Mostly mud use, some trail riding around the house but usually end up playing in the mud. I know Ill lose some power going up in size but I think it'll be fine.
