In the structure of a radial tire, which parts function independently of each other?

Question

DentroTest · Accepted Answer

The correct answer is the tread and the sidewalls. Radial tires are constructed with cord plies running perpendicularly to the direction of travel (from bead to bead). This architecture allows the function of the sidewalls (providing flexibility and comfort) to be decoupled from that of the tread (providing traction and contact). As a result, the sidewall can flex over road irregularities or during cornering without deforming the tread's contact patch. This improves grip and stability, and reduces heat buildup compared to bias-ply (diagonal) tires.
