Is that what the sticker says? Our '98 SE says 225/75/15.

 

Stock 99 with 235 General Grabber AT2's. Only changes are: K&N air filter, Royal Purple 10-30, Precision Auto Injectors upgrage injectors, and a fresh tune up. Local travel (mountainous area) about 18.5+. Highway on the flat best is 21.69. I'll eventually change out the gear lube with synthetic as well as a tranny fluid change and I might squeak a bit more out of a gallon of fuel. The above #'s reflect a vehicle a loaded vehicle (tools, luggage, and passenger). I'm very pleased........

 

My door sticker says 215 and lists 225 as optional. And my Jeep had few options. Manual windows and locks, vinyl seats, sawblade steel wheels, basic AM/FM, white 2-door, gov't. vehicle, etc.

 

Ok, my bad, your's sounds just like ours, plain jane SE city fleet vehicle but with 225s OE.
