pretty sure that's stock size on the GC (that's what's on my XJ). you shouldn't have to change the speedo.

(a) Other tires sizes and brands may also be used. (b) Available w/Up Country suspension only (c) Standard on 5.9 Limited
1998 5.9 225/70R16


Stock Tire Diameter Conversions
215/75R15= 27.696850393700785
225/75R15= 28.287401574803148
245/70R15= 28.503937007874015
225/70R16= 28.401574803149607

Your suggestion of:
235/75R15=28.87795275590551
As long as you keep in mind that any change in tire size affects the speedo, ABS, odometer, brakes, and things like that you are well within the 15% range for trucks and SUV's- cars are more like 5%. One thing to be careful with though, is that even with the stock suspension Jeeps have a tremendous amount of articulation in the live axles- so be careful about tire rub.

AND NEVER EVER PUT BIG WHEELS OR "DUBS" ON A VEHICLE THAT IS MADE TO SEE DIRT! The only possible exception would be wheels that are 20 inches or greater in order to run tires over 40 inches.
