As Bobby says, there isn't yet a perfect answer. Since you are new to the whole thing, I think that the easiest, most hassle-free way to handle the situation is to replace them with what is already on there. If your candidate TM has 15" tires as standard equipment, then you must be looking at a 3023 or a 3124 - all the other models have 14" tires. This means that the OEM tires are Goodyear Marathon ST225-75R15 tires. Be sure that the installer balances the wheels before he puts them back on the TM.
By the way, are you sure that the tires need to be replaced? Is it possible that the previous owner replaced them within the past couple years? There is a 4-digit date code (WWYY) at the end of the long DOT code that is molded into the sidewall. It is probably on the inner sidewall, so you have to crawl under the TM to see it. Anything newer than 3 years or so is probably OK to keep.
