The perfect size wheel for the america is the one that was on it from the factory.The perfect tire for mounting to that perfect wheel is an avon venom for wet or dry.
yes they have Grzegorz has put a 17"rim and I belive its 5.5 or 6.0 wide on the back of his bike and is running a 200 wide avon on it.. I am runnig a 16" 5.5 wide on the back of running a 180...
Any major changes need to be done to run a bigger tire, I mean other than getting a bigger tire. Did you guys send your hub in and have them lace it to a bigger hoop, (like Buchanans)is that the easiest way to do it?
