I dunno, but I'm wondering if all the folks posting MPG's (who are running larger diameter tires) have gone through the process to accurately calibrate their speedometer/odometers. Mine had 32" ers on it when I got it, and now has 33's. I know it's a pain in the arse to jump through the hoops to calcultate my mileage on a regular basis.
Oh well, one of these days I'll get that programmable Autometer speedo.
John Sherwood '79 FJ-40 .... to few MPG's, I'm sure.

I couldn't resist. Ask Chuglife...we went wheeling last weekend and he used up a whole tank of gas, I used barely over 1/4 tank of diesel in mine.

My 20mpg was based on a 105 mile drive in the snow at 55mph between hawthorn and Tonopah..
Speedo had nothing to do with it.
Taller tires mean you actually go farther that what is registering...

You'll be waiting a while...24v components are supposed to be very durable, runs less amps. We all know how long a 12v Toyota starter and alternator lasts. Heck, I just replaced my wife's original starter in her 1986 Tercel which has 290,000 kms. Just imagine a 24v Land Cruiser alternator, with oil cooled bearings. BUT...you never know with electricals, I guess. I have fairly good access to parts and my BJ74 only has 92,000 kms on the odometer...like I said, you might be waiting a LONG time to get your last laugh.
Not trying to toot my own horn...but you asked. Anyway, noticed you're in Vancouver...why aren't you driving a diesel?And my mileage calculations took into account the larger tires...confirmed by GPS readings.
I am averaging 14-15 in the 65, F135 with Aisan 1bbl and stock exhaust manifold, 32" tires.
To and from Rubithon in the 68, F145 with Aisan 2bbl, header and 33s I averaged 15-16. Like the others, I am often tinkering with the carb and ignition.

SizzleChest - are you correcting the mileage you read on your odometer for tire size?
Bigger tires will result in fewer miles recorde per rev, so fewer MPG...
Migh not be as bad as you think!
Access to GPS? You take a trip, calculate your error and then correct whenever you check mileage...
Correcting the mileage is a big step. 28 inch tires where stock. So you need t use the same equation you do when calculating what speed you are really traveling at.
New tire size/stock tire size * Speed (or miles on odomter.
I have 33 inch tires so
33/28*50=59 Miles per hour actual speed when my speedometer shows 50 MPH
33/28*100= 118 actual miles driven when my odomter shows 100 miles driven.
Use the actual miles driven to figure out your miles per gallon.
You can purchase an adapter that will correct this before the odomter so you are seeing actual speed and mileage.

There are 6 different speedo gear options for the 80 and older FJ40s. I usually have good luck with the 16x7 drive and 32s, so an adapter may not be necessary. For you.
Hey Romer, how about a linky on the adapters for the FJ60 folks who don't have ANY speedo gear options? THanks.

Wes...I did the previous calculation using a conversion factor that I had in my head. Apparently, it was closer to Imperial gallons rather than the US one. So, I looked it up on the internet and came to the following calculations:
26.28 MPG (US gallons)
31.67 MPG (Imperial gallons)
Not as spectacular as I thought, but still plenty good. I have yet to service my injectors (which is due right about now). I should try to figure out what my old Poofinder V6 was getting...that one was horrible! Cheers.
well this is timely as i JUST,, got back from a w/e trip. i drive a '75 FJ55, its SOA on 36" sx's with a very modest but strong running 2F, i pulled my off road trailer with me and altogether about 7-800# of "stuff" loaded.
i used 28 gallons for the whole 3 day w/e, i didnt keep track of the difference in on/off road miles but i did notice that the return trip was 141 miles of mtn type hiway and upon topping the tank in town i had used 8 gallons.

My '72 with stock F and 32" TSL-SX gets about 10-11 mpg using a Holley 350 and centrifugal advance Mallory Unilight distributor. With the old stock distributor I averaged 15 mpg. I'm in the process of replacing the Holley with a Jim C. stocker unit so we'll see where it comes out.
The '96 gets around 11-12 mpg in city driving and about 14-15 mpg highway (with typical cruise at about 75 mph). It's running 33" tires.
