26 mpg with 35” tires!!

[bywaysnothighways]

I’ve been relying on the built in computer and my scan guage 3 to get an idea of mpg. I typically see between 22-24 on my scan guage which takes the tire difference into account vs 20-22 on the dash mpg guage. I am only ever seeing the number for that specific trip. Well I reset my meter and did a full tank and was blown away that it was actually much better than I expected. I went 360 miles on the dash which equals 392 when accounting for the tire change and used 15.063 gallons. That comes to 26 mpg! I was expecting closer to 20 because in my experience the dash gauges always seem higher than actual tank calculations.
I’m gonna do a few more tanks to make sure it wasn’t a fluke but at the moment I’m pretty happy. I’ve been wondering if the people complaining about super bad mpg aren’t calculating it correctly/have bad driving habits/ super heavy tires or all 3. I try to drive with the engine off as much as possible. I really wish I had more control over it because i know it is running more than it needs to. But overall I am pretty happy with that.

What tire size is the LC actually reading for? I feel like the 285/70r17 that I’m running needs an adjustment for tire size as well

I suspect it’s a combination of drag and lead foot. You have nothing on your right, not even crossbars, that’s definitely helping. Still, 26 seems high. Outlying enough that I would recommend you double check your work! What is the elevation gain/descent of the miles you drove?

the dash is reading as if I had the stock tires which are 31.5 for the 1958. With the tire change for me it is undercalculating by 9%

Right nothing on the roof. I'll definitely be checking it again on the next tank to make sure there aren't any issues, like the pump clicking off too early etc. All my driving starts and ends at the same elevation (1400ft) so that isn't relevant

The Method 705s look great on your LC. What size are the KO3s you are running? Did you lift the truck? Can we see a shot from the front showing the poke?

They are 315/70r17 Goodyear territory MT No lift.

Great combo . I'm amazed that these fit without rubbing on a no lift truck. Do you have any issues with throwing up rocks/dirt/debris past your mudflaps and onto the side of the LC?

Yes I do. I want either the flares that come standard on the other trims or some aftermarket wider flares and some larger mud flaps. Need about one more inch of coverage.
