MPG with 37” tires?

[Troublemaker]

Highway is 13.7? That ain't right.

What tires?

Most are posting 15+ on Nittos for example.

35/12.50/17 Faulken Mud Tires -

I am not happy at all with the mileage. I got rid of a 2015 Ram 2500 HD with 3.73 gears and it got better MPG than this truck. I expected @15mph was my expectation. Of course dealer say " No problem found"

Minimal trucks running 37s, but your mileage won’t bust 13-14. Probably 11-12, and the truck will drive awful with 3.21s at least at highway speeds. As stated, 3.92s or bust for 37s. Hell for 35s too.

A lot of it depends on the wheel and tire as well, a lighter AT on a 20x9 will definitely drive better than say a heavy/aggressive MT with 10-12 inch wheels.

Im getting 13-14 with Toyo Rt 35's...Id say 10-11 for sure
