If you run larger tires and have not regeared having over drive off keeps the over drive from kicking in and out, which could cause the transmission to overheat. Also when towing you don't want the over drive on for the same reason.

I can see that. But the OP didn't mention what he was running.

I gained about 1-1.5 MPG in suburban driving by turning mine off.
Speeds under 50 MPH make the engine work too hard in OD.
It's become a habit. I've worn letters off the button.
If I'm going to be on the highway at or above 55 MPH for at least a mile or two, I let it go into OD. (hilly areas excepted)
