Wheel assembly with internal pressure reservoir and pressure fluctuation warning system

When a tire blows out, are the method of making it possible, and each wheel (1) control of the vehicles equipped with at least two wheels A rim (2), Including the tire (3) interlocked with it, the above-mentioned method, The fluid which swelled each tire (3) to working pressure (PE) at base temperature (TR), and was compressed in; base temperature (TR) to the 1st pressure (PP) higher than the working pressure (PE) of the above-mentioned tire, At least one above-mentioned rim. When only the 1st predetermined threshold (Vs*) is lower than the above-mentioned working pressure (PE), make it flow into at least one tank interlocked with (2), make the internal pressure (Pi) of the; above-mentioned tire 連通 the above-mentioned tire (3) with the above-mentioned tank (4), and it; predetermined frequency. Measure the internal pressure (Pi) of the above-mentioned tire (3) by (F), calculate change (Vp) of the above-mentioned internal pressure per; unit time (Pi), and the above-mentioned change of; internal pressure (Pi) is equivalent to reduction, When larger than a predetermined value (VP*), the step which generates an alarm signal and tells a driver the; above-mentioned alarm signal is included.
