Try this rpm/mph calculator. In your case type in the mph, gear, and tire size then click the mph its pretty close. These calculators are a good tool when your thicking about gear changes.
What the tire says on the side (14x32) means almost nothing. It just gives you a ballpark figure.
To get a true tire size, take your roll out and divide it by 3.1416 and that will give you a exact tire height. Your 105 rollout, 105/3.1416=33.42

Wow that calculator isn't even close for mine...does that mean the converter is too loose? I have 32 x14 goodyears and the rollout I think is 102. Last time out I was right around 67-6800 at the eighth and my mph was 110. I have a 5.14 rear gear.

Sounds like your converter is not locking completely up. These equations are usually within a couple of hundred RPMs. Supposedly your converter never fully locks up. But should be 95% locked up on the big end.
