15.5

12.4 all city and very short commute, 16-17 highway at 75mph here in Florida. Lots of variable will come into play with results here. Driving habits, terrain, climate.

Running 37x12.5R17. with a lift. Just drove back from Tennessee to Michigan.....Windrock trip to get the badges...

I averaged 18.8 mpg running 72 to 75 mph.

High 17's / low 18's around town driving. High 18's / low 19's highway 4.10 gears 3.6l

It really depends how you drive. I'm up 3.5" on 12.5x37x18. If I drive smooth on the highway and cap speed at 65 I get around 21. City drops to about 17. If I'm hammering it, highway at 75 gets you about 18-19 and city 15.

I am on 37x12.5r17 Pats and on a Metalcloak 3.5" Lift. I am relatively heavy with skids / front and rear bumpers / sliders / evo tire carrier. 8SPD auto and 4.10 gears still. Where i live it is very windy and i have to go up and down a mountain to get into the city.

With the hardtop on i am getting 15/17 MPG
With the hardtop off and doors still on i get 15 / 14 MPG

It really is circumstantial your MPG. IF you never go over 60 MPH your mileage will improve. The faster you go on the freeway the worse your mileage will be.

Ummmmmmmm 12.5!

Don't know, didn't buy it for gas mileage.......... I just wanted 37's.

 

[AZDustMuncher]

I was getting 15 completely stock. I don't look or want to know what I get now!

Tough one.. as was mentioned already... one size (conditions) does not fit all.... My Maxxis Creepy's are really soft and heavy.. with top and doors off, loaded for the trail, at 7k elevation in the Placerville, Shaver, or Tahoe area... lucky to see 14MPG …

Unloaded, flat at sea level... 14.5 at 70mph.. And it improves to 15 at 60MPH.

That is one reason why I trailer my tires to the trail head and swap them out.. stock tires and rims consistently 17MPG, while loaded and towing at 70-75 ~ 15-16 MPG..

But like others said as well... I did not buy it for MPG..

hope that helps..

I'm on 37x13.50x20's on a 4" lift and I average (depending on my foot) between 14 and 16 mpg.

Before I added the rooftop tent, I was getting 18-19.5 MPG, now it looks like I’m around 16-17ish.
