TJ Fuel Consumption 31 inch tires?

You didn't really buy a Jeep for fuel economy or highway handling did you? I hope not.

And if the handling is truly bad, the previous owner probably screwed something up on the suspension or alignment. TJs handle pretty good on the highway. Not like a sportscar but not bad either. Going from 31", which is what the Rubicon comes with anyway, to 30" is not going to make much difference at all.

What is the stock tire size?

31" is stock for Rubicons, 30" is a factory optional and very common stock tire size for TJs, not sure about the smallest tire size available on base-level Jeeps.

I think we have reached a milestone here. Someone actually thinking of going to a *smaller* tire. :)

Seriously though, I run 31's, had 30's stock with the >Just bought a 1998 TJ with new 31 inch Goodrich tires. I think these larger

Smallest size on base TJ's is 215 x 75 x 15.

I would recommend leaving the 31's on, and if you think the handling is bad, then have the wheel alignment checked and have the tires balanced. I have

31's on a stock '02 Tj and the handling is PERFECT.

I recently upgraded from 30" to 31" tires and didn't notice a decrease in handling or gas mileage. Gas mileage on a TJ is horrible anyway (I get around 15) and it doesn't handle like a Porsche, but it shouldn't handle terribly either. I'd say something else is wrong beside the tire size.

actually your larger tire size is screwing with your spedometer and odometer. Nick

215 x 75 x 15....metric right....??

I grew up with metric but since the bro's and dad used standard....that's easier for me to use!....

So how does it break down again?

So they have metric and standard in their code?

standard....that's

I'm averaging about 17mpg on 31s with my 4.0L.

Factory spec tires are much smaller - 215 by 15 or something. You did not say if you have a 4 or a 6, auto or std. My 99 6 and auto was quite peppy on factory tire, although it did hydroplane badly and was totaled once because of that. I moved up to 235's and it is a little less 'zippy' at the stop lights but it does work better going through the creek up at the farm. You should find that the turning radius is quit tight.

With the bigger tires you will be higher = more wind, also the odometer may be off a bit. You could be going faster than you think, but there will be a nice police officer that can help you with that.

'bout the same on 30's and 4.10's (I know, makes no sense, will somebody buy me some TIRES )... Starting to hurt at 2 bucks a gallon for gas. I drive my wifes Volvo on the commute when she does not need it... 30 mpg is nice, and it's a fun car to drive.

Always nice to get back into the Jeep though!
