But with an auto tranny (Aisin) I don't want to mess with how the computer controls the shift points.
It won't "mess" with anything. Tens of thousands of newer Rams and other brands running around on slightly larger tires. No problem.
If you have a srw, it's got 3.42s, correct? Bigger tires won't help in towing power, although it will be minor with the HO unless you're towing close to or over max rated.
Frankly, they "look" better, IMO, with bigger tires as well.
But you may not need the load capacity of the bigger tires?
