FIELD: transport.
SUBSTANCE: invention relates to automotive industry. Proposed wheel 1 comprises tread 2 communicated with reservoir 4 to feed medium till first pressure, tire 3 mounted on said tread and having inner space 3' inflated to working pressure. Note here that the latter is lower than aforesaid first pressure. Note also that one valve 5 can control communication between reservoir 4 and inner space 3' of tire 3. Valve 5 comprises at least one elastic element coupled with at least one closing element 17 designed to open/close one hole 9 in valve 5 to make reservoir 4 communicate with tire 3 when pressure in tire 3 falls below working pressure. Said elastic element features elasticity factor K varying by 10%-40% in temperature range of -50°C to approx. +50°C.
EFFECT: higher efficiency of tire pressure control.
