Tread blocks of the same size with a large number of slots can boost tire noise. This observation comes from tire specialist Sergey Mishin, who shared insights in a recent interview with socialbites.ca. The noise level of a tire is also visible by examining the markings on its label. Mishin explains that the tread pattern plays a crucial role in how loud a tire sounds while driving. When every tread block, often called checkers, is uniform in size and there are many grooves, a car tends to generate more noise during motion than with tires that have varied block sizes and fewer micro-cuts. This pattern creates more turbulence in the tire-road interaction, which translates to audible vibration inside the cabin. Mishin notes that the micro-cut count is a key factor that influences acoustic performance. Attribution: Sergey Mishin, tire specialist.
European tires come with a noise rating on the label that accompanies the original sale. This label uses a scale that ranges through quiet to loud, typically classified as A, B, or C, with A representing the lowest noise and C the highest. Mishin emphasizes that under European standards the maximum acceptable noise level is 72 decibels, a threshold that is roughly equivalent to a loud conversation between two people. This labeling system helps consumers compare tires not only on grip and rolling resistance but also on acoustic comfort. Attribution: Sergey Mishin, tire specialist.
Earlier, Oleg Rastegaev, a tire specialist and tester for Autoreview, discussed the issue in an interview with socialbites.ca. He pointed out that tires with a low profile are often linked to a higher risk of a crash, a claim that underscores the importance of choosing tires that balance handling with safety and comfort. The discussion reflects a broader consensus in the tire industry that performance characteristics like stiffness, profile, and tread design must be considered alongside noise when selecting tires.
