Modern Tire Sizes

I tried to do a search to see if this was covered already. I know the original size of the rims and tires, but I don't know the equivalent in the modern sizing.

tirerack.com says that the 7.60x15 converts to 225/75/15, but it also lists about 4 other sizes. With the narrow rim of 15x5.5 it would be easy to pick a tire too wide. And I'd like the speedo to run as accurate as possible.

Also, what is the bolt pattern on these?

Mine is a 55 Clipper.
