Carbon fiber's wheels ability to tolerate a wide range of temperatures without becoming brittle or deformable depends not on the carbon itself but on the epoxy that surrounds it.
Clincher Wheels. Although lighter weight is the primary benefit of a composite wheel—particularly a carbon-fiber one—there are also advantages to be gained in the noise, vibration, and harshness arena. Metal wheels, including steel and aluminum, transmit a great deal of high-frequency NVH from the road through the suspension and into the car's structure. Carbon-fiber wheels damp that energy better, cutting it out of the equation where it begins.
