Pneumatic vehicle tire comprises e.g. tread strip and tire rim, where heat insulating layer in the form of foamed- and open-cell material with air spaces is arranged on tire rim-inner side, and is dimensionally stable at tire inner pressure

摘要

Pneumatic vehicle tire (1) comprises a tread strip, a tire sidewall, a tire bead (2) with a core and a core profile, and a tire rim (3), where a heat insulating layer (4) in the form of a foamed- and open-cell material with air spaces is arranged on a tire rim-inner side and the open-cell material is dimensionally stable at a tire inner pressure of at least 6 bar. A compressed air penetrates unhindered into the open-cell material to maintain its heat insulating properties. The tire bead rests on the tire rim-inner side. The tire and a tire cavity (5) warm during operation due to hysteresis.
