Abstract
A combined tread depth measurement tool and pressure gauge for treaded pneumatic tires includes a housing, an abutment surface, and a pneumatic pressure sensor. The pneumatic pressure sensor includes a measurement element with a graduated numerical indication of pneumatic pressure on at least one side and a colored indication of tire depth on at least one side. The colored indication includes at least three distinct colors, the three distinct colors each having widths corresponding to ranges of tread depths in reference to a terminal end of the measurement element. A combined tread depth measurement tool and pressure gauge for treaded pneumatic tires includes a body assembly and a spring clip. The body assembly includes a housing with three color bands having distinct colors, a pneumatic pressure sensor, and a measurement element. The spring clip includes a sliding portion and a clip portion with a tire engagement end.
