I was wondering the same thing.

 

They actually do make the truck feel more stiff and a bit harder ride.

With the tires and wheels I dropped about 1-1.5 mpg vs the 17's. Between the Ranch hand bumpers and wheels im averaging 10-11.5 mpg.

 

Looking good!

 

Did you account for the difference in the odometer?

 

I don't think there is much difference in the odometer/ speedo. I tracked the speed with my GPS And it's about 2.5 mph off.

I really haven't given any thought to the odometer really. I service the truck to the severe service schedule so it's a moot item to me really.

I'm due for an oil change next week, I'm going to ask about that though, I'm
Going to have them see if they can get it a little closer on the speedo.
