Here is a link to a tire size calculator I've use for years. I work the numbers until I get where I want and then check the size on a online tire site (usually tirerack) for load ratings. You don't want to know how many hours I've spent doing this in the past LOL!
BTW: Muskratt2, I have an uncle that lives your way and I'm only an hour and a half away. I ride up routes 8 and 40 towards Rocky Mount on my Triumph or Ducati a few times during riding season, Hi neighbor.
