The tread of a tire or track refers to the rubber on its circumference that makes contact with the road. As tires are used , the tread is worn off , limiting its effectiveness in providing traction. A worn tire tread can often be retreaded. The word tread is often used incorrectly to refer to the pattern of grooves cut into the rubber . Those grooves are correctly called the tread pattern, or simply the pattern .
The tread area of stairs is the part you step on, the whole width of it. It is not the instep, ie the upper part of the stair or step.
A tire with a tread has less contact with the road surface than one with no tread. When racing you want to maintain as must tire surface in contact with the racing surface as possible.
Hydroplaning occurs when the tires' tread is unable to expel enough water to maintain a rubber contact patch on the road. The function of tread is to allow the "high" part of the tread pattern to cut through by forcing water (and other road grit) into channels and grooves surrounding the tread blocks. When the water gets too deep for the tread grooves to cut through it and force it between the tread blocks, the "high part" of the tread blocks lose contact with the pavement and looses traction by hydroplaning.
I believe it is the same as on a tire, a Tread.
The width of the contact patch of the tire on the road.
Increases grip if there is water on the roadway the water can enter the holes in the tread and not interfere as much with the rubber contact with the road.
i think its called a tread
Collectively they are called 'tread'.
it is a tread
it is a tread
This is called the tread. It must be durable and heat resistant, and its grooves help keep it in contact with the road, especially when it is raining.
