Abstract

Noise Reduction in Pneumatic Tires A pneumatic tire having a tread design for reducing the amount of noise generated by the tire when rolled on a given surface, is disclosed. The tread comprises a plurality of circumferentially spaced lugs defining therebetween respective grooves, the lugs all being substantially similar to one another in configuration. Each of the lugs and its corresponding groove adjacent thereto in a given circumferential direction together defining a pitch of specified length which circumferentially is dimensionally identical to the pitch of certain others of the lugs and their corresponding grooves and is yet dimensionally different from the pitch of still others of the lugs and their corresponding grooves. The lugs are arranged such that certain (though not necessarily all) of the lugs and their corresponding grooves of the same pitch adjoin each other in succession in the form of a pitchidentifiable group differing in pitch from an adjoining pitch-identifiable group of still others of the lugs and their corresponding grooves. Such groups adjoin each other in a preferred circumferential series to define a pitch sequence which over its circumferential extent has excitation peak frequencies that do not coincide with the resonant frequencies of the tire. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to limit the scope of the invention in any way. [CA1050869A]
