Answer
Ron,

First, you need to record all the information about the tires.  

My guess is that they are ST type tires and the form the size takes is ST225/75R15 Load Range D - but you need to look at the itres to see WHAT the size and the Load Range are.  With that information, you should be able to get the proper tires on it BEFORE you move it.  That way you only do this once!
