You check the mileage on your fj55?

Really!?

 

[jkl72-40]

I dont even want to look...... but it would be interesting to find out

 

[RHINO]

i didnt find much change when i went to 33's, but i did find a slightly better MPG when i went to 36, but only on flat ground, speed and mileage went way down on hills. i only know this through rough checks, when taking trips on flatter parts of my state vs. hilly parts. so i guess it really depends on where you mostly drive. sorry i dont have hard numbers.

I do have some anecdotal experience here...
Coming back from Moab in '01, on 33s, fully laden, I was getting approximately 14 MPG. Figuring about a 10% odometer error. Fresh rebuild on the late F...
These days, with the 35s, I'm getting maybe 13.5 on the highway. Figuring maybe 13 or 14% odo error. Fresh rebuild on the 2F.
But the 33s were mud terrains, now I got swampers. And I'm a little higher these days (SOA). And a little heavier. And that roof rack isn't helping either.
But I don't pay much attention, nor do I fill up my tank very often.

Put the 37" on, buy a civic, shut up...

I've said it in 20 threads: If you're driving a LandCruiser and you care about gas millegae, you need to re-evaluate your life.

I do not have before #'s, but I get 18mpg with 37's and 4.11 gears... SBC350/th350, SOA pig, no roof rack.
GPS verified.

Thank you for that OH so wonderful input that answers nothing about the original question. Please point out where I say I was concerned with the gas mileage? You can't point it out because I never said I was

Perhaps read where I said "This is more of a curiosity thing than anything" THEN offer some input. Hard for me to give a crap about gas mileage when I put maybe 5k miles on my car a year

do we need a group hug??

 

[zuluzeugma]

Yeah, that did kinda come across "dick-like". EVERY single week there is a new thread from some noob called, "gas milliage" or "12MPG!?!?" or something similar. I get super sick of it and wish the MODS would just delete them. If I would have got my head out of my ass for 5 seconds I would have realized youre not a noob. Anyway, my apolgies. The point still stands though: no one checks cause no one wants to know the true answer

Lower HWY RPM's, but more rolling resistance. I've heard going from 31" to 35" with the same driving style is a toss up. My buddy drives a 98' durango on 39" TSL's with 5.13's and gets about 11 MPG which is only 2-3 less than when he had 31" BFG A/T's once upon a time...

Sorry for being a dick...

You might be doing even better than you think:

When I went to 33s from stock, the change was 16% or so, according to GPS. I don't know what 35s do...

My mileage is still crappy.

My low mileage piggy is a source of beauty and pride.

My personal policy is: if I can afford to drive this, that is my business.

That said, I have never done the math yet- because my tank leaks when full so I never quite fill it to the top - and therefore have no reference point to measure the gallons I put back in.
