The invention discloses an explosion-proof and anti-skid emergency wheel for a motor vehicle. The wheel consists of a tire, an explosion-proof emergency wheel, an inner wheel hub seat, explosion-proof emergency wheel retaining semicircular keys, an emergency wheel conical surface mounting steel bowl, an anti-skid spacer, a retaining nut, an outer wheel hub seat, a charging connector, an overpressure control valve, a minimum air pressure alarm and an anti-skid device, wherein the explosion-proof emergency wheel retaining semicircular keys are arranged in three semicircular key grooves of the outer wheel hub seat; the explosion-proof emergency wheel is built in an emergency wheel conical surface mounting groove on the outer wheel hub seat through the explosion-proof emergency wheel retaining semicircular keys, and the anti-loose spacer and the retaining nut are arranged; the charging connector, the overpressure control valve and the minimum air pressure alarm are arranged on the outer wheel hub seat; and the inner wheel hub seat is arranged on the outer wheel hub seat. In the wheel, when a tire burst accident is suddenly encountered, the tire is instantly substituted by the emergency wheel to run so as to avoid accidents; the anti-skid device can prevent the accidents from being produced by skidding of the tire; tire demounting equipment is not required for repairing the tire; resources and energy are saved; and pollution emission is reduced.
