Question: What is the standard gearing on the 2012 Automatic. I have seen conflicting information betweeen 3.21 and 3.73, even in same posts. Is there a definitive source?

A. If you have 225/75/16 tires, and:
1. you turn ±1850 RPM at 60 MPH, you have 3.21s
2. you turn ±2150 RPM at 60 MPH, you have 3.73s
B. If you have 255/70/18 or 255/75/17 tires, and:
1. you turn ±1675 RPM at 60 MPH, you have 3.21s
2. you turn ±1950 RPM at 60 MPH, you have 3.73s
