    • A vehicle wheel with inflatable tyres, mounted on the same rim. One of the tyres (1), called a summer tyre, has tread suitable for summer use and at least one additional tyre (10), called a winter tyre, with a tread suitable for winter use. The winter tyre (or tyres) is mounted on the side of the summer tyre and is, in summer conditions, not fully inflated and hence not in contact with the road surface, because its circumference in its semi-inflated state has a shorter radius than that of the circumference of the summer tyre. The winter tyre (10) is securely attached to the outer surface of a concentric volume accumulator (7), which is part of the wheel rim and functions as a constantly available spare tyre. When inflated, the winter tyre (10) can expand, so that it has the same outer radius as the summer tyre (1) and thus also comes into contact with the road surface. After that, the pressure of the summer tyre is lowered and the area of contact with the road surface is redistributed to the winter tyre (or tyres).
    • 具有充气轮胎的车轮,安装在同一轮辋上。 称为夏季轮胎的轮胎(1)之一具有适合夏季使用的胎面和至少一个称为冬季轮胎的轮胎(10),其具有适于冬季使用的胎面。 冬季轮胎(或轮胎)安装在夏季轮胎的一侧,并且在夏季条件下,由于其半充气状态的圆周的半径比半充气半径小,所以夏季不会充分膨胀,因此不与路面接触 夏季轮胎的周长。 冬季轮胎(10)牢固地附接到作为轮缘的一部分的同心体积蓄能器(7)的外表面,并且用作不断可用的备用轮胎。 当膨胀时,冬季轮胎(10)可以膨胀,使其具有与夏季轮胎(1)相同的外半径,并且因此也与路面接触。 之后,夏季轮胎的压力降低,并且与路面的接触面积重新分配到冬季轮胎(或轮胎)。
