I want to repaint the aluminum wheels on my 2001 Tiburon. Who sells it he correct silver / pewter color?

is there a color name or color code

 

This is considered special info and some vehicles have the info on the spare tire cover inside the back of the vehicle , some have it on the glove compartment door.

Your best bet is to check with your local Hyundai dealership parts dept. They may require your VIN. With that they can tell you everything you need to know.
