The invention discloses a tire gauge. The tire gauge comprises a casing with a gas inlet hole, an inflating valve assembly connected with the casing and a nut column, wherein the inflating valve assembly comprises a valve rod, a first screw part and a second screw part which are arranged sequentially as well as a nut nested at the first screw part; the nut column comprises an insertion part and a limit part; a stepped hole which penetrates through the top end and the bottom end of the casing and is matched with the nut column is formed in the casing, the insertion part of the nut column penetrates through the stepped hole to be connected with the second screw part of the inflating valve assembly, and the limit part of the nut column is propped against the casing. Fixation of the tire gauge and a wheel rim is divided into multiple sections of fixation, for example, fixation of the wheel rim and the valve rod and fixation of the valve rod and the casing. The tire gauge and the wheel rim are more firmly connected, separation of the casing and the valve rod due to influence of centrifugal force generated by the casing during tire rotation is not easily caused, and the connection is more reliable.
