35s and mpg

[Usa450r]

What is everyone getting mpg with 35” tires? I have 800 miles on my new truck and getting approximately 13 mpg city driving. Is this normal? Do you think this will improve?

I can’t help you on the MPG but I’d love to see pics of your setup.

I wish I could delete the screen for mpg. I use the same fuel per week on 35’s that my 6.2 Silverado did on 33’s. when the fuel light comes on, I know to get fuel. I definitely didn’t buy a Hemi looking to get good fuel mileage. They love gas.

I have the 5.7 with a 26 gallon take and wish I had the 33 tank. Mileage running between 16.5 to 19.8 depending where my foot is on the throttle. Have a set of falken A/T on her, couldnt stand the factory road tires, which I sold at a good price.

Also Ive had her 9 months and have 23000 miles on her.

You can't delete options but you can hide them. One can configure screen not to show fuel data.

damn I’ve had mine 9 months and coming up on 14,000 and thought that was getting up there. You got me beat by a mile.

by a few miles, actually

Just drove from SLC, UT to Phoenix, AZ. Pulled a 8.5x16 enclosed trailer with a UTV that weighs approximately 1700 lbs. The trip was mostly highway. Some travel at elevation. I stayed between 68-75 mph on the highway. Tow/Haul mode was engaged. I got around 9 mpg for the trip.

11-12mpg on 35x12.50r22 with Borla Exhaust and Mopar CAI - neither of which helped the mileage lol but damn it sounds good and looks even better!

Just got home 350 miles round trip. Costco 91 octane
80% of total trip was 80 to 85 MPH.
Buddy in 2019 Nissan Rouge had super hard time to keep up same number of passengers in each vehicle did 24 MPG. And Rouge smelled like every thing on fire when we reached destination.
He claimed under normal driving conditions he got 30 Mpg. 170 hp belt/chain driven transmission.
He said it was abuse to vehicles.

Fuelly is in my siggy. Roughly 2500 miles at this point, but that is every drop of gas I've burned.

That’s some low effective gearing. I’d have to run 43’s to match that!

You mean "high" effect five gearing don't you? Small number gear ratios are high gears and larger number gear ratios are low gears. 2.93 is a high or tall ratio.

I meant what I said because the 2.93:1 is a lower or smaller ratio than 3.92:1, though It turns out that gear terminology is dictated by the final output speed and not the ratio of the gear.

Here’s an interesting article on gear ratios and the impact it has on performance.
