What Causes Tire Bead Unseating?

[ElainaAnn]

Tire bead unseating refers to the phenomenon where the tire separates from the wheel rim. Below are detailed explanations of the causes: 1. High-speed driving: During high-speed driving or when encountering potholes, the tire pressure may become excessively high due to increased tire temperature. This converts significant pressure into force acting on the bead lock, which can easily lead to bead lock failure and subsequent tire unseating. 2. Improper installation of bead lock rims: The rim requires a specialized structure that includes a bead lock ring. During installation, the tire's bead wire must be positioned outside the rim, then secured tightly against the rim using the bead lock ring to ensure a firm connection between tire and rim. This fastening mechanism operates independently of air pressure, which is precisely why it effectively prevents tire bead unseating.
