When I was looking for my wheels , the first two I ordered ended up being discontinued. I ended up having to evaluate 3 different wheels and their specks , then trying to find a tire size that would work for my usage and wheel size.

It was a learning experience for me ! I used this site > http://www.rimsntires.com/specs.jsp < to help me evaluate all the different options and what kind of an effects they would have. I'm an amateur and I needed all the help I could get. So I really liked this calculator and I used it a lot.
