1. An alert system for vehicle tire, comprising at least an alert device provided at a tire valve of the vehicle tire, wherein said alert device comprises:
- a signal arrangement which comprises a cap, a signal generator received in said cap, and a power supply arrangement which comprises a first contact unit connected to said generator and a second contact unit; and
a connector, for connecting to the tire valve of the vehicle tire, which has a detecting cavity for communicating with an interior pneumatic pressure of the vehicle tire and comprises;
a conductor disposed in said detecting cavity;
a conducting unit normally positioned apart from said connector;
a resilient element disposed between said connector and said conducting unit for applying a force against said conducting unit towards said connector;
a power inlet connected to said second contact unit of said power supply arrangement; and
a power outlet connected to said signal generator, wherein when the interior pneumatic pressure of the vehicle tire is higher than a predetermined standard pressure, said conducting unit is spaced apart from said conductor such that said power inlet and said power outlet are electrically disconnect with each other, wherein when the interior pneumatic pressure of the vehicle tire is lower than said predetermined standard pressure, said resilient element pushes said conducting unit to contact with said conductor such that said power inlet and said power outlet are electrically connected to transmit electricity from said power inlet through said second contact unit of said power supply arrangement to said power outlet and generate a warning signal.
