Tubeless pneumatic vehicle tire and method for producing a tubeless pneumatic vehicle tire

摘要

A layer (3) of closed-pore foam is adhered to the tire (2) inner surface. An Independent claim is included for the production of the tire. Preferred Features: The foam is located within the area of the tread at least. It forms in part, the airtight inner layer. It has predominantly constant thickness of 1-5 mm, especially up to 2 mm. The cells are about a tenth of a millimeter in diameter, up to a maximum of 0.5 mm. The foam is thickened in the region opposite the deepest section of the rim (1). This thickening runs the rim depression (1a), when the tire looses pressurization. Adhesive holds the foam to the tire. Inside the tire an at least partial filling of open-pore foam is included. Preferably the foaming liquid is spun into the unvulcanized or vulcanized tire, during manufacture. Vulcanization completes foaming and hardening.
