Re: TJ Fuel Consumption 31 inch tires?

So they have metric and standard in their code?

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.
