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.

:LOL:

Clears it up perfectly. Ive learned so much since Ive joined this site. Good stuff here. Anyhow, here are my weak numbers

30" tires, 3.23s, and 20k on the clock give me 672 wheel revs per mile, 13,445,421 total wheel revs, and 43,428,710 pinion bearing miles. I think....:confused::lol:

Oh I seeeee now. I was like I know Im not THAT dumb :duh:.

So....31.5" tire x Pi /12...divided into a mile is 640.25814044116878........and that x 220,000 miles is 140,856,790.8970571316 and that x 3.73 gears is 525,395,830.046023100868.

I think thats quite a few times around. :nutz:

I guess its kinda tough for us to bitch if our bearing gives out. It seems to be rather busy....

Good job Trav. I made myself clear. You got about 525 million pinion bearing revs and I think mine was 588 million but I don't wanna look again to see.:coffee:

We need a :takeabow: smiley. :lol:

If I was smart and ran a shorter tire it would be higher but I wanted to be cool and get all-terrains. That was a big mistake I will say.
