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.

There were a couple of cars with the European styling that use
metrics like the '79 Mustang Gina 220/65R390 at a thousand dollars each.

'bout the same on 30's and 4.10's (I know, makes no sense, will somebody buy
me some TIRES <g>)... 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!
