also: ふみづら
tread (of a wheel); step (of a stair)
Technical term for the horizontal surface that is stepped on: the tread of a vehicle's wheel or tire, or the horizontal part of a stair step.
The tread of the tire is worn down.
Widening the stair tread makes it safer.
Standard kanji spelling; 面 is read めん here.
Alternate reading using 面's づら reading; less common but still encountered.
Compound of 踏み (fumi, 'stepping') + 面 (men or zura, 'surface'). The reading ふみめん uses the on'yomi of 面, while ふみづら uses the kun'yomi.
