FIELD: automotive industry.
SUBSTANCE: disclosed is tire (100), made with possibility of rotation around axis (AXR) of rotation, and comprising: tread block (110) forming at least part of tread (120) of tire (100), and loop (200) comprising primary capacitive component (210), wherein at least part of primary capacitive component (210) is located at first distance (d1) from tread (120) and inside tread unit (110), and primary inductive component (220), at least part of which is located at second distance (d2) from tread (120) in direction of inner area of tire (100). Tire (100) further comprises polling device (300) comprising power supply (330), communication circuit (310), and secondary inductive component (320). Secondary inductive component (320) is located on the same side of tread (120) as primary inductive component (310), wherein at least part of secondary inductive component (320) is located at third distance (d3) from tread (120), wherein third distance (d3) is greater than second distance (d2). Method is also disclosed for wear indicator (190) in tire (100) tread unit (110).
EFFECT: higher sensitivity and reliability of tires wear indicator.
