A method for monitoring vehicle tires by: 1) determining that a complete deflation or blow-out occurs if speed variation of one wheel of a vehicle is larger than or equal to a threshold value, and wheel speeds of other wheels of the vehicle are approximately constant, 2) associating a blow-out or complete deflation speed increment ratio &Dgr;V2 with a ratio of an normal impeller diameter Rnormal to a complete deflation impeller diameter Rdeflation, and 3) detecting whether a real-time speed increment ratio &Dgr;V of one wheel is greater than or equal to the blow-out or complete deflation speed increment ratio threshold &Dgr;V1, wheel speeds of other wheels are approximately constant, and a real-time speed increment variation rate is greater than or equal to the blow-out or complete deflation speed increment variation rate threshold &Dgr;V1/&Dgr;t.
