ALWAYS anticipate going to a larger tire. It WILL happen. You wheel it twice a year yet drive it everyday. 4.88 with 31's will be too steep and kill mpg. (we're talking real bad mpg) I used to have 36" iroks with 5.29 and could cruise 70 on the highway at 18-20 mpg.

31's.....4.10/4.30
33's.....4.30/4.56
35's.....4.56/4.88
36+.....4.88/5.29

remember, base your decision as a daily driver. 33"/4.10 w/ smooth rolling radial will work fine. A bit piggish up highway hills, but still ok. Put the gear $$ to something else.
