Is It Normal for New Car Tires to Have No Rubber Hairs?
1 Answers
Normal. Rubber hairs are small rubber burrs on tires, known as "little braids" in the industry, caused by vent holes in the tire vulcanization mold. Nowadays, technologically advanced tire manufacturers have already resolved this issue. More details about tire rubber hairs: 1. Rubber hairs do not increase tire noise: Tire noise mainly occurs when the vehicle is driving at high speeds, and the tire rotates rapidly, compressing and releasing the air within the tire treads. This continuous "compression-release" process generates noise. The faster the speed and the heavier the vehicle, the greater the noise. Under such high-speed rotation, the effect of rubber hairs is negligible. 2. Rubber hairs do not enhance grip: This is only theoretical. If the tire surface has rubber hairs, it may make the surface rougher, theoretically increasing friction. However, the tiny rubber hairs contribute insignificantly to the tire's overall friction. 3. Relationship between rubber hair length and tire quality: The length of rubber hairs depends on the equipment and manufacturing process used to make the tire. The length of rubber hairs cannot be used to judge the quality of a tire, and rubber hair lengths vary among different tire specifications and models.
