18s on a sol at 7.5 won't shouldn't be able to tuck. If your going to do 18s you gotta do air. But 17s it what I would go for man. 17x7 that way it would look good and not gaughty being so big, (especially on a little del sol), and 7 is easier to tuck. Good luck with whatever you decide. What color is the del sol if I may ask?
