MPG loss

[MaxSteelTX]

Anyone else notice a significant MPG loss after installing the 3.5” Readylift and Nitto Ridge Grapplers?

I went from averaging 15-16 city to 12, and only 14 Highway. For me, The look is worth the MPG loss, just wondering if y’all noticed the same thing....

More wind resistance (lift higher in the air) and rolling resistance as well with those tires in my opinion

2” Bilsteins and 33.5” Toyo open country iii. 14.5 city and 18 hwy

The additional friction to turn those heavier and knobbier tires... there‘s probably 2 mpg, then there’s the lift. Sounds reasonable. Truck in your signature pic does look good though!

Yes. Every single truck I’ve ever owned, I’ve either lifted or leveled. Every single one lost MPGs after

It really is important to have your speedometer corrected. Software does not just control what’s the speedometer says it also affects shift points for the transmission, mpg display calculation, and other aspects such as stability control. Your mpg shown in the center display is not accurate. Your odometer is also not accurate so you cannot hand calculate mpg accurately either.

Vehicles are really effected by tire resistance and aero for mpg. There is a reason why Chevy used 32" Duratracs on their Trail Boss trucks instead of 33". Probably 1-2 mpg right there.

Also your axle ratio is lowered with larger tires over stock. Lower rpm, however it takes more effort to turn the tires which effects mpg.
