Rear axle ratios and impact on towing
Suppose you have a choice between two axle ratios, say they are a 3.09 and a 3.45. And let's say the vehicle has an 8 speed transmission, so there's plenty of gear flexibility. Ok, so there's roughl...

Your in theory also has to assume that everything ELSE is equal, ie all them variables you are talking about, otherwise, it is not as close to equal to equal test as one should compare this types of things. Take a rig with say 28" tires with the 3.09, and compare it to a 3.45 with 30" tires, and you will have pretty much the same shift points at the same speeds etc. Now what will happen, is in reality, potentially the 3.09 will be a bit faster than the 3.45, as those 30" wheels and tires are bigger, heavier, take up more drivetrain HP, so will be a bit slower. Probably not a lot to worry about, but none the less, slower due to the taller diam tires.
Many ways to change out the how a given rig may do vs another one.
