They are also a little cheaper to burn up on the track and at least for now there is also a larger selection in the 18" size.
Finally, if you go off the track, the extra sidewall rubber can save some rim/suspension damage.
There is a difference between "show" and "go."
If you look at real race cars, they all have sidewalls, but in street cars the sidewalls are dissapearing. Unsprung weight is important when you are looking for an edge.
Look how much more sidewall even a Formula car has over cars with 19s and 20s.
