no. the only difference is that your tires will be more expensive for 17" rims.
It will depend on which rims will fit your car. Having 16 or 17 inch rims will have a significant jump in the price of your tires.
No, 17 inch rims can not fit on 16 inch wheels.
17 inch wheels are better than 16 inch .as,17 >16. They are better as they have greater area in contact with road providing better contact force.Hence 17 inch are better than 16 inch beacuse they provide greater stability.
That would be a 1 inch difference. 16 inch is shorter then a 17 inch rim.
SIZE TIRES, that You can fit on: 14" rims: 235/60/14 15" rims: 215/60/15 16" rims: 225/50/16 17" rims: 235/45/17
NONE 2003-2006 Rubicon Rims were only 16" diameter which means cheaper tires than 17" and taller sidewalls which is better for offroad. Newer and larger JK (2007+) Rubicon rims are a different bolt pattern and will require wheel adapters to fit.
You might choose 16 inch rims over 17 inch rims because the cost would be lower with the smaller rim size. The cost of tires would also be less.
