I am looking for information on different gearing rpm,speed tire size. On a 2003 dura max with a 5speed Allison

Tire size 265-75-16
4-high and 4low with 3.73, 4.10, and 4.56

Tire size 33's
4-high and 4low with 3.73, 4.10, and 4.56

I've looked and looked I can't find anything. Thanks. Kyle

There is a badass wheel speed calculator Excel sheet on here somewhere that someone made for all the Dodge transmissions. It would be simple to put in the Allison ratios into it.
