This paper presents a high-resolution measurement system for fast-rotating tires. The developed system is compatible with and can be integrated with the tire testing machines used in industry research facilities. A field programmable gate array controller with a high clock rate triggers a short duration strobe flash capturing a clear instant image of a rotating tire based on an encoder reference signal. Since the rotation of a tire on a testing machine is periodic, the system can effectively capture the deformation of a rotating tire at a high equivalent sampling frequency. The Complementary Metal-Oxide-Semiconductor (CMOS)-based high-resolution low-cost system can be employed to measure tire deformation associated with sound generation. This was implemented by synchronously measuring sound with a microphone array. The validity of the developed system was investigated by experimental evaluation. Then, the system was implemented at the tire testing facility, and tested by rotating a tire at a drum speed up to 100 km/h and capturing images at every 0.025 degree rotation.
