Off-road cycle tires, colloquially called knobbies, [4] may be found on motocross and enduro motorcycles, ATVs, and mountain bikes. [1] Tires for single-track vehicles and ATVs have a curved profile such that some tread only contacts the ground during turning. Depending on the model of tire, an off-road capable tire may or may not be approved ...
The scrub radius is the distance at the road surface between the tire center line and the SAI line extended downward through the steering axis. The line through the steering axis creates a pivot point around which the tire turns. If these lines intersect at the road surface, a zero scrub radius would be present.
An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), [1] a quad bike or quad (if it has four wheels), as defined by the American National Standards Institute (ANSI), is a vehicle that travels on low-pressure tires, has a seat that is straddled by the operator, and has handlebars, similar to a motorcycle. As the name ...
Skid marks from aircraft tires on a runway. A skid mark is the visible mark left by any solid which moves against another, and is an important aspect of trace evidence analysis in forensic science and forensic engineering. Skid marks caused by tires on roads occur when a vehicle wheel stops rolling and slides or spins on the surface of the road.
The underside view shows the arrangement of the 18 tires (wheels). Shown in blue in the underside view are the axles, drive shaft, and differentials. The legend for labeled parts of the truck is as follows: tractor unit; semi-trailer (detachable) engine compartment; cabin; sleeper (not present in all trucks) air dam; fuel tanks; fifth-wheel ...
In contrast to today's ANSI definition of an ATV: "a vehicle that travels on low pressure tires, with a seat that is straddled by the (single) operator, and with handlebars for steering control", an AATV is intended for multiple riders, sitting inside, and will usually have two control sticks (and in some cases a steering wheel or joystick ...
Cutaway diagram of a rim and tire from an ATV Cross section of a bicycle rim A wooden bicycle rim with tubular tire The rim is the "outer edge of a wheel, holding the tire". [ 1 ] It makes up the outer circular design of the wheel on which the inside edge of the tire is mounted on vehicles such as automobiles . [ 2 ]
This friction acts as centripetal force and tries to bend the outer tires inwards. The tires get deformed due to bending and the contact area between the wheels and the ground decreases. This in turns decreases the frictional force between the outer tires and the ground, causing the vehicle to drift during cornering.
