I personally like 17's... they look good and have size, and the price of tires is pretty good, and they are still pretty light. I think 18's are still worth gettin, but 19's are just too much money for tires and too heavy, they would be nice on a car that doesnt matter about speed, well if you dont care about speed and how heavy they are then its fine, imo they are just too heavy and expensive to replace tires. 17's-18's are the way to go.
