you running at 70mph, flat-land highway, no wind, no load??

Trying to figure what my gear-ratio is in the Rodeo; started at 4.3; but with running 32" tires, I've never really questioned before what it is now.

I'm right at 2,100 rpm's at 65mph, and almost right on 2,500 rpm's at 70mph

Don't know. Let me check it for you.
The tag on the rear diff says 4.3.

Just over 2500 at 70 mph on my 245 70R 16s (29.4"x7.5"). In a 40 mph zone. Your welcome!

In a 40 mph zone. Your welcome!

Now, now, don't need to be gettin any tickets on my behalf!! :eek:

Thank you!!

(new diameter/old diameter)xold axle ratio = new axle ratio

example:
(29" / 32")x4.30= 3.896875 (3.90)
