If the Ashcroft calculator is off, like really off, its because something was entered incorrectly.
You posted it man. Jesus, at least I am sticking to my guns here.
You came at me at with insults and sarcasm. I didn't say anything to you I didn't say anything derogatory to anybody for some reason you got this thing up your ass about this thread. Your initial statement was wrong. I've got facts to back up that it was wrong. Why don't you just drop it move on and quit being confrontational. I have enough bullshit at work and in real life I don't need it here in my hobby Life too.
Let's make nice and kiss and make-up.
With 4:12's on 33" tires I run at about 2250 going 55mph.

I ran across this formula recently;
Desired tire size divided by stock tire size times stock gear ratio equals new gear ratio.
33/29*3.54=4.03 go to the nearest available, like 4.11
29/29=1.000000000*3.54= 3.54
30/29=1.034482759*3.54=3.662068966
31/29=1.068965517*3.54=3.784137931
32/29=1.103448276*3.54=3.906206897
33/29=1.137931034*3.54=4.028275862
34/29=1.172413793*3.54=4.150344828
35/29=1.206896552*3.54=4.272413793
Here is what GBR has for a reference;
3.54, 3.9, 4.11, 4.14, 4.43, 4.71
