6.4 MPG with level and 35s

[King nothing]

What kind of MPGs are you guys with a level and 35 inch ATs getting. I’m looking at 2 inch Thuren springs in the front and 1 inch rear and 285/75r18 (35x11) all terrains. She’s already thirsty, so I’m hoping it’s not too significant of a drop. Would a 35-12.50 be significantly worse than the 285? 3.73 gears

I have 35x12.5x20's but not leveled. '16 CC Laramie 6.4/3.73 gears. I avg 13-14 mpg per tank, hand calc, running 89 octane.

MPG on mine with mudders are down atleast 2-3mpg from Nov thru March...Some of that loss can be attributed to winter blend fuel also...The tires are 275-70-18 (33.5")...10 ply...They weigh 60# ea...My truck is leveled in the front with Timbrens...

You lost 2-3 mpg with stock size mud tires?

Do you think the 89 octane helps with your mileage? I’ve been running 87

To be honest, I don't know. I always run 89, other than the few times I tried 93 while towing. I couldn't tell any difference in performance or mileage, so I just stick with 89.

I'm running a 2" level on 295/65R20 Toyo AT2 which is a 35" tire on a 2016 2500 mega cab with 6.4L and 3.73 gears. I get hand calculated average of about 11 city / 15 highway. And that is on 50 psi front / 45 psi rear and I corrected the speedometer using an AEV ProCal. I also use a pedal commander which I would assume the mpgs take a small hit from that too.

I think that’s better mileage than I get with the stock size tires lol

Ha. When I was stock I was getting 13/17. Our highways here keep the speed low though. That's the key. I never get above 65 really. 55 is the sweet spot it seems for me.

I'd happily pay the gas bill over having to drive 55 everywhere.

My wife would crap a brick if I set the cruise at 65 on the interstate. I have been running right at 70 which is the speed limit here and running 60 on the 55mph 2 lanes. Don’t think im getting much better than 12.5 average

55 mph is the sweet spot for my 37x12.50s as well. Evic gets up to 13.0 - 13.6 at 55.

I usually chug along at 60 - 65 and the evic stays around 12.0 - 12.4.

When I'm "in a hurry" and cruise around at 70 it drops to 11.4.

hand calc is usually about 1.2 mpg lower than evic.

2 inch thuren, 35x12.5x18 Toyo AT's and I get 11-12 mixed, mostly consider what I do city driving... My commute to work is only 16 miles each way, about 10 of it on highway.....

I got right around 16 on vacay to north carolina this spring, when not in traffic...
