what size tires should I Run? 23f/22r or 21f/20r??? I do lots of trail and getting into GNCC

also does anyone do wheel spacers for gncc or is it too tight

 

Stay stock width, don't add wheel spacers, you'll get stuck bet. trees! As far as tires, I would run the 20 rears. The 22 rear may be beneficial in lots of mudd where ruts and clearance will be a problem...but the 20's will be ideal in most conditions. For the front, some run 21, some run 22...22 gains you a little clearance, and allows more rubber for clearing obstacles, others belive there is easier steering and control in 21's and like the slightly lower ground clearance. You will hear different opinions on the fronts....either will work, but 20's on rear will be perfect!

 

Don't add spacers and limit the wheel offset. I like larger tires on the rear 22's. I pushed a 400ex up a hill at Ironman last year with my trailbazer simply because I could get to the bottom of the rut. Set your front for best steering response.
