The invention relates to a dismantlable rim (1) comprising an inner emergency wheel (3) and antifriction systems, with which it is possible to drive with deflated tyres without damaging same. The inventive rim (1) comprises two complementary annular parts (4,5), which are equipped with threaded reciprocal coupling means (10). The body of the dismantlable rim (1) comprises two complementary annular parts (4,5), namely: a first part (4) and a second part (5). Both of the aforementioned complementary annular parts (4,5) are provided with lateral retaining rings (6,13) for the tyre (2). The tyres (2) are modified in order to adapt same for use when deflated and to determine a guided movement on the inner wheel and reduce the rotational movement on the rim. |
