The 5 on 4-1/2" bolt pattern, like what is on the Contender ST205/75R14 Radial Trailer Tire w/ 14" White Spoke Wheel # TTWA14RWS, is the way to determine if a wheel will fit your current hubs.

This is one of the most common bolt patterns for trailer wheels and you can measure your bolt pattern by either measuring from the center of one bolt to the diameter of your pattern directly across from it, or simply measuring from the center of one bolt to the center of an adjacent bolt. The 4-1/2" measurement is what you would find if you were to measure the diameter. If you measure bolt-to-bolt, then you will find that to be 2-5/8" on center.

I am attaching a link to a helpful article on bolt patterns and how to measure them for you to reference.
