The indicator traditionally would be a dial indicator; today dial-type and digital indicators coexist. The earliest expansion of "TIR" was total indicated run-out and concerned cylindrical or tapered (conical) parts, where " run-out " (noun) refers to any imperfection of form that causes a rotating part such as a shaft to "run out" (verb), that ...
Typically run-out is measured using a dial indicator pressed against the rotating component while it is turned. Total indicated run-out (TIR) is a technician's term for the measured run-out of any rotating system, including all forms of run-out, at the measured point. [3]
total indicator reading; total indicated run-out: For measurements of eccentricity and other deviations from nominal geometry TOS: top of steel: TOL: tolerance, tolerancing: TSC: theoretical sharp corner(s) See discussion at SC and POI. TY: type: For an explanation of "type" abbreviated as "TY", see the example given at "CL" meaning "class ...
The radial run-out can be expressed as the peak-to-peak value as well as harmonic values. Radial run-out imparts an excitation into the vehicle in a manner similar to radial force variation. It is most often measured near the tire's centerline, although some tire makers have adopted measurement of radial run-out at three positions: left ...
A backplate with a female (self-releasing) taper may seat on the matching male taper of the tapered spindle nose (for lathe work) or of an adapter plate with the same nose, to be mounted on a table. This system improves the repeatability of the mounting concentricity down to a very small total indicated runout (TIR) value. Subtypes:
The state-run Chinese Academy of Sciences has said the pension system will run out of funds by 2035. About 22% of China's population, or 310.31 million people, were aged 60 or over in 2024 ...

A runout may include any of the following: Runout (climbing), a section of a rock climbing route with a long gap between points of protection; Run-out, an inaccuracy of rotating mechanical systems, specifically when a tool or shaft does not rotate exactly in line with the main axis. Run out, a method of dismissal in the sport of cricket.
