Abstract
Abstract The improved tire gauge of the present invention provides a multi-functional tire testing tool capable of determining the tire tread depth, measuring the tire pressure, and removing and replacing the tire stem cores from the tire valve. The tire tread depth checker and a stem removing element are attached to a conventional tire gauge. The tire tread depth check has an indicator probe which is positionable between the tire treads and which slidably engages the cylindrical body of the conventional tire gauge. A linear scale on the cylindrical body cooperates with the probe to provide a measurement of the tire tread thickness. A stem core removing element is attached to the top portion of the tire valve engaging head of the conventional tire gauge. The stem core removing and replacing element has a rod like element with an axial bore and slot at the bore opening for receiving the tire stem.
