Abstract
The wheel of the present invention reduces road noise without using a special tire. The wheel includes a wheel body and a silencing chamber formed around the wheel body. The silencing chamber communicates with an air chamber in the tire via communication port. The phase difference between a compressional wave in the air chamber and a compressional wave returned to the air chamber from the communication port cause attenuation of the road noise.
