Re: What's your fuel mileage on 33s?

'99 XJ with 108K miles, 5-speed, 33x12.5x15 BFG AT KO tyres, K&N intake, widened throttle body, aftermarket muffler, roof rack: 15 mpg around town with lots of stop and go. No freeways here, but from memory, highway isn't much better at only 16 mpg.

I get 15-16 mpg mixed highway and city.
I am currently not running a thermostat b/c my electric fan controller for my fans doesnt work anymore and all it does is kill my battery. I try not to stop for long lol

So at worse you get 32 mpg, at best 36 mpg. Not bad, not bad at all.

as someone who did this when they were broke in college... i think your MPG calc is off. i agree, it pretty much puts the speedo dead on.

i remember when i realized 5th was useless on the highway and resorted to winding out 4th gear. basically i found that the vehicle was motor limited, and just didnt have enough torque to turn 5th gear on the highway.

if your concerned about mileage... gear your junk. youll get back a lot of driveability (that maybe you dont know youve lost) and see benefits offroad.

i went from 3.55s to an axle swap with 5.13s. that had the opposite problem, i could redline 5th gear and still wasnt doing 70mph.

I am stuck paying more in california, $3.60/ gal. a rip off high tax state, ugh! I sure like Texas. Newsum is basically doubling the gas prices for us out here. But he will give you a tax break if you buy a stupid electric car. I suppose I have bought somebody an electric car with all the gas tax I pay.

So you get about 50 liters of fuel which is about 12.5 gallons US.

How many kilometers do you get?
