Bling and performance have no correlation. Race cars generally have to
meet specifications. For example NASCAR calls for 15" steel wheels. F1
is even more restrictive. The wheels RE 13" and all tires are supplied
by Pirelli. Pirelli has several different models based on stiffness,
wet/ dry, and so forth but they're all Pirelli. At one time Bridgestone
was in but they were dropped. I don't know why. IndyCars run Firestone
on 15" wheels.

I'm curious what race cars run 17/18/19" wheels.
