The part of a wheel that bears upon the road or rail.
The part of a rail upon which car wheels bear.
Distance between the centerlines of a vehicle's tracks or wheels.
The part of a tyre in contact with the road surface.
Load-bearing surface of a trail or road.
The trail's surface.
The grooved or patterned face of the tire that maintains traction with the road surface. Tread is measured by the depth of the grooves.
Otherwise known as track, it suggests the measurement of the width of a car the from the center line of the wheels.
The portion of the tire that comes into contact with the road
the grooved surface of a pneumatic tire
the part (as of a wheel or shoe) that makes contact with the ground
apply (the tread) to a tire
That portion of a tire that comes into contact with the road. It is distinguished by the design of its ribs and grooves. It is molded of tough rubber for high traction and low wear.
Width of a car measured from the center line of the wheels. Sometimes called the track. Also the pattern on the surface of a tire.
The grooved or patterned exterior part of the tire which contacts the road surface.
The part of tire that contacts the ground.
That part of the tyre that comes into contact with the road.
The surface pattern of a tire.

The travel surface of the trail.
The part of the wheel that rolls on the ground. Not to be confused with "thread."
The region of a tire designed to contact the ground. It is molded of tough rubber for high traction and low wear.
The section of the tire that is in contact with the road surface.
That portion of a tire that comes into contact with the surface of the road and is designed to allow the air flow to cool the tire and to channel water during wet weather.
The tread of a tire or caterpillar track refers to the pattern visible on its circumference that makes contact with the road. As tires are used, the tread is worn down limiting their effectiveness in providing traction. A worn tire tread can be replaced with a process known as retreading.
