Importance of Lamellae

Among car enthusiasts, the term "Lipuchka" has firmly taken hold. However, if we delve deeper, it becomes clear that the tire in the contact patch does not stick to anything, especially on ice. In other words, any tire can provide traction, but for different road surfaces, as well as for different weather conditions, there is a specific set of tools, and how suitable it is depends on how effectively the tire will brake.

Contrary to popular opinion, on ice, the main weapon of the tire is not the studs at all. Yes, studs are effective and make handling on icy roads as efficient as possible, but they are not the primary element of winter tires.

The main element of winter tires is the lamella, and in non-studded tires, it is the only one.

This is explained by the fact that in winter, on roads, under any weather conditions, there is a large amount of water. The main mass, of course, is removed by such elements as longitudinal and transverse channels, but at the same time, the water from the contact patch does not completely disappear. Especially on ice, where the thickness of the water film is no more than 1-2 mm. It is here that the lamellas come into operation. They literally absorb water, leaving the contact patch as dry as possible.

What conclusion can be drawn from this? Quite practical for every car owner. The depth of the lamellas directly depends on the overall depth of the tread. If on a tread with a residual depth, you feel a significant deterioration in handling, it means that the lamellas are no longer coping, and the tires should be changed.
