For only the lousy several hundred dollars you might get for them, consider keeping the wheels for a second set instead. My XJ runs 30 inch'er DynaPro MT tires on 15's for muddy trails/roads in the summer, and during the winter my second set of 15's run 27 inch Blizzaks for unfreaking real glare/black ice conditions. I've been considering a third set of wheels for deeper snow conditions, and a fourth set for long distance summer highway driving, i.e., using up the rest of the Blizzaks rubber, (after the special surface compound has been worn away). Swapping out wheels/tires to meet your various conditions could enhance your experiences.., just a thought.
Bottom line, smaller tires, are lighter, get better gas mileage, usually quieter, and could be available to you if you keep 'em stacked on their treads in your nice looking garage, (that is.., if yours is like the others in the picture).
Looks aren't everything.:eyes:
