The bead seat refers to the portion of the wheel rim that provides radial support to the bead of the tire. It is located below the rim flange and is designed to securely hold the tire bead in place when the tire is inflated. The bead seat is crucial for maintaining the structural integrity of the tire-wheel assembly and ensuring a proper seal between the tire bead and the rim.
Key features of the bead seat include its shape and dimensions, which are engineered to match the corresponding shape and dimensions of the tire bead. This ensures that the tire remains securely mounted on the wheel rim, even under various operating conditions and loads. Proper engagement of the tire bead with the bead seat is essential for safe and efficient vehicle operation.
