Abstract:
1. A combined tread depth measurement tool and pressure gauge for treaded pneumatic tires comprising: a housing comprising a first end, a second end opposite the first end, and an abutment surface substantially flush with the first end, the abutment surface having at least one dimension width sufficient to simultaneously engage portions of tire tread on opposing sides of a tread void; and a pneumatic pressure sensor within the housing and extending from the first end to the second end of the housing, the pneumatic pressure sensor comprising at the second end of the housing a connector sized to mate with a tire valve stem and core, and a measurement element slidingly engaged with the pneumatic pressure sensor at the first end of the housing, wherein the pneumatic pressure sensor is configured to thrust the measurement element outward to an extent proportional to an elevated pneumatic pressure applied to it and to leave the measurement element so extended when the elevated pneumatic pressure is relieved, thereby providing an indication of pneumatic pressure; wherein the measurement element comprises a graduated numerical indication of pneumatic pressure on at least one side of the measurement element and a colored indication of tire depth on at least one side of the measurement element, the colored indication comprising at least three distinct colors, the three distinct colors each comprising widths corresponding to ranges of tread depths in reference to a terminal end of the measurement element.
