摘要

The tyre has a vertical partition (a) dividing its inner chamber into two separate compartments (b, b1). The partition has a divergent edge joined to the tyre's inner surface, a thin flexible central section (c), and an inner edge (f) shaped to engage with a sealing joint in the shape of a rail (g) and cradle (h) on the wheel rim's inner surface. The partition is made from rubber-covered reinforcing layers (e) and a cable (d).
