Tried a search and couldn't find what I was looking for, So...
I know this is a dumb question, but what is the diameter of a 33x12.50 tire. I am using an RPM calculator and I need this diameter to get an answer. Thanks for any help.

I think I need the true diameter...or do I? Maybe I am confused. Any one know if this calculator needs the "true diameter" or will entering "33" in the tire diameter box give me the desired answer? Here is a link to the calculator:

Yeah I figured I could do that. I'll get a tape and do it.
Thanks everyone.
