Mike B. with the stock rear end gears and 9R22.5 tires, that will go 65? Any idea what the RPM is at that speed? (winding up pretty good, I'd imagine? 3500 or so?)
Are you running 9.00 x 22.5's on a 2-1/2 ton truck? That sounds small to me, I would have thought they would be 10.00 or even 11.00's.
And yes the rpm is up there!
