Haven't looked for tires myself yet...and a source in Ohio wouldn't help anyway..... but the 9.00 - 20 is all you need for a size.

It is an older system of measurement where the 9.00 is the tire(rubber) size. (The larger the number the bigger the tire) and 20 is the rim diameter.

If you call around to some tire shops that do a lot of trucks they should be able to get just about anything you need.
