rengasjännitys

Rengasjännitys, often translated as "tire tension" or "tire strain," is a concept related to the forces acting within a tire. It describes the internal stresses that develop due to the inflation pressure and the load the tire is supporting. When a tire is inflated, the air pressure inside pushes outwards, creating tension in the tire's rubber and reinforcing cords. This tension is essential for the tire to maintain its shape and structural integrity.

As the tire rolls and encounters external forces, such as the weight of the vehicle, cornering forces, and road surface irregularities, these internal stresses can change dynamically. The casing plies and bead components are particularly subjected to significant tensile forces. Understanding rengasjännitys is crucial in tire design and engineering. It influences factors like tire durability, rolling resistance, and ride comfort. Excessive or uneven rengasjännitys can lead to premature wear, reduced performance, or even catastrophic failure. Tire manufacturers employ sophisticated modeling and testing to manage and optimize these internal stresses for optimal tire performance and safety across various operating conditions.
