TJ Gas Mileage

[chans]

I've been looking at some TJ Wranglers now that they are cheaper in price since the release of the JKs and wondering what kind of gas mileage people get with 35" mud tires and either 4.10, 4.56, 4.88 gears? Mainly looking at the I6 engine and will that be enough power to turn 35" tires with 4.10 gears? Thanks

turn them yes, fast? no and gas mileage forget it

the girlfriend has an 04 tj with 32 inch tires and the gears are 3.07 and she gets about 15-17 mpg... it has the 4.0 in it...

I have 37" tires and 4:88 gears, I get around 14 MPG around town.

I have a 33 inch tires on my TJ with 4.10 gears. I usually get anywhere from 15-18 mpg with the 4.0. But I have a K&N, high flow exhaust manifold etc. on the jeep which has helped with the ponies a little bit

i used to get 19 consistently with 33" at's but I had the 4 banger with 4.88s

I'v got 4.88's, AOD, 35" MTR's, and I6. 14mpg. Anything higher geared will be a gutless pig. Even at 4.88, power is marginal at best.

Wow 15-17 would be nice. I got a solid 12mpg in my tj with 3.55s and 33's.

I did very little freeway driving though.

i usually get somewhere around 12 or 13 with 35's and 3.73's. i have the 4.0 and a manual tranny. i'm most likely planning on 4.56's for the axles when i can afford it. this is what my dad has and he averages 18 or 19 mpg on the freeway and has even gotten 23 on the way to moab! of course, the tailwind did help, but his jeep has good power and he rarely downshifts for hills and headwinds are no problem.

4.56 or 4.88 sounds like the way to go. Thanks for all the replies. Your Dad's Jeep has 35" tires also?

What RPMs are you at when going 65?

yeah it does. i believe he runs somewhere around 2500 rpms at 70 mph, somewhere in there.

37's 4:88, manual trans-- 12-14 depending if up or down Hill (ha ha ha)

 

[benjy]

35" mtrs, 4.56s, 12-13mpg around town, 17 down to moab, and 14 back with a crazy headwind

with the 4.0

 

[RKCRWLR]

35 Toyos, 5.13s, 6 speed, 4.0L with Edge chip, winch, ARB bumper and 2 blitz cans, etc (ie its heavy)... 14 mpg. Got the same when it was stock.

 

[RockChucker]

what rpms do you run at on the freeway?

 

[pennieslj]

I run 35s and 4.56s w/ auto. Turns about 2300 rpm at 70 mph. I get about 14mpg as an average.

 

[RKCRWLR]

what rpms do you run at on the freeway?

I turn just under 2800 at 65 mph in 6th.
