Yeah we realize that too, but we found that our configuration actually got up more easily with 6 12" tires. That, and we use 6 12" tires every year and didn't want to break tradition

I might be thinking of the 8" pneumatic tires that came with the kit, not the 12" ones. Because I remember us trying to larger tires that came in the kit and with our drive train it actually went up worse.
