Default Looking for gear chart
Hey guys, a while back I had seen a chart on here that showed what your best RPM's would be with like tire size and gear size I believe. Does anybody know what I am talking about. If so I'd appreciate some help trying to locate it again.

Thanks all!

Yellow is more efficiency, black is OEM, blue is more power.

I have 3.92 so I'd actually be running more efficient by putting on 35's instead of the 33's that I have now? Obviously a little loss of power comes with that tho.

No you will not be more efficient. One thing to remember with that chart is that the RPMs are with a trans gear ratio of 1:1(no overdrive) at 60 MPH. Your Ram has a 0.67:1 second overdrive, so the RPM in the chart will be much lower than that. You will be more efficient with a 31" tire and 3.92 or 33/35" tire with 4.56 IMO

You must multiply those RPM numbers by .67 to get the accurate RPM if you are in 5th gear.

OR..... If you want to do the formula yourself it's:
mph x gear ratio x 336
_____________________
Tire diameter
x
trans gear ratio

70(mph) X 4.56 x 336 = 107251.2
107251.2 / 33(tire dia) = 3250.03
3250.03 x .67(5th trans ratio) = 2177.52

2177.52 RPMs at 70 mph in 5th
