The term "sidewall" refers to the vertical part of a tire that connects the tread to the bead. It plays a crucial role in maintaining the tire's shape and providing support during driving. The sidewall is designed to absorb impacts and protect the inner components of the tire, contributing to overall vehicle safety and performance. In addition to tires, the concept of a sidewall can also apply to other structures, such as buildings or containers. In these contexts, the sidewall serves as a barrier or support, helping to maintain the integrity of the structure and protect its contents from external elements.
