Title: Kouji Shibata: Innovator in Pneumatic Tire Technology

Introduction

Kouji Shibata is a notable inventor based in Nishinomiya, Japan. He has made significant contributions to the field of pneumatic tire technology, holding a total of 7 patents. His innovative designs focus on reducing tire noise and enhancing performance.

Latest Patents

Shibata's latest patents include a pneumatic tire featuring a circumferential groove designed to minimize air resonance noise. This tire comprises a tread portion with a groove that has a pair of side walls. The groove is strategically placed within the ground contacting width of the tread under a standard loaded state. The standard loaded state involves mounting the tire on its regular rim, inflating it to 70% of its maximum air pressure, and loading it with 88% of its maximum load. The axial width of the groove ranges from 0.2 to 0.35 times the ground contacting width. Notably, at least one of the side walls has a nonrectilinear configuration with multiple axially deviated parts. This design continuously alters the conditions of air resonance in the groove during operation, effectively reducing tire noise.
