Thanks for the info Buckeye.
I was just throwing around the idea of larger rims and tires because we live down a dirt(mostly rocks) road and I was thinking bigger rims and tires might help out with the rough terrain, especially if my kids are going to be learning to ride this. What would your thoughts be? In the ad it says 12.5 tires, what does that mean? 12 1/2 inches or is that something else?
