A tire pressure device comprises a nozzle and a tire pressure detector. The nozzle is extended with an inflating rod at one end, a through hole penetrates laterally through the inflating rod, a pin penetrates through the through hole. The tire pressure detector is configured with a base, an adjusting groove penetrates through the base. The inflating rod of nozzle penetrates through the adjusting groove of the base. The end of the inflating rod penetrating the adjusting groove is connected with a fastener. The base is clamped by the fastener together with the pin, so that the pin may be formed as the positioning axis of the nozzle. The swinging of the end of fastener may be used to adjust the angle relative to the tire pressure detector, such that the rod-like nozzle structure may achieve the stepless angle adjustment function, and thus the tire pressure detector may be stably abutted against the bottom of wheel rim.
