AI Technical Summary
Existing methods of inserting a nonwoven fabric-rubber composite into the sidewall of a pneumatic tire do not sufficiently improve the rigidity of the side section, necessitating further performance enhancements.
A pneumatic tire design incorporating a nonwoven fabric-rubber composite with specific basis weight, rubber composition hardness, and tensile stress ratio, enhancing the rigidity of the side portion by using a nonwoven fabric coated with a rubber composition having a Type A durometer hardness of 60 to 80 and a tensile stress ratio of 1.5 to 4.0, aligned to improve tire moldability and braking performance.
The increased rigidity of the sidewall improves braking performance and tire moldability by utilizing a nonwoven fabric-rubber composite with optimized properties, specifically a basis weight of 50 to 300 g/m² and a rubber composition hardness of 60 to 80, aligned to enhance tire expansion during molding.
