Great! You found the page I was referring to. The 32.1" diameter is with no weight on the tire (and you need this value to check for clearance at the top of the wheel well or at the sides when the wheels are cornering). The revs/mile figure IS with weight on the tire and works out to a TS of 2482mm. I think that is going to be VERY close to the number that would be dead accurate.
