Where did you get that number from??? Unless my calculator lies 27 x 3.14 = 85.59 and 85.59 / 12 = 7.065. Am I missing a step or something?
No I put it in the wrong order or forgot the feet to mile part....

Tire diameter times Pi (3.14159) that total divided 12. Take that total divide it INTO 5280 and get wheels revs per mile. Take wheel revs per mile and multiply by odometer which gives total wheel rotations. Multiply THAT times gear ratio and get pinion bearing rotations.
