Smaller wheels will save you a ton on tire cost. Also, the smaller combo will be lighter, give you a bigger contact patch and fatter sidewall.
But, there are catches:
While most 15" alloy wheels will clear your brake calipers, most 15" steelies will not. Also, the 15" wheels generally have less backspacing – usually 3.75" or less. This means your tires will stick out from the Jeep more. Some peeps don't like this.
In the 16" wheel size, a lot of the 35" tires offered are E-rated, which means they'll be harsh for on-road riding. I have E-rated tires, but I bought em deliberately, since I like more of a "truck" feel to my Jeep. Again, some peeps want a nice, cushy ride.
You will have more tire choices in the 17" size, but in many cases you'll pay more for tires alone than you will for tires AND wheels in the 15" size.
And 18's...eh, don't do it.
