Tires
Nominal rim diameter
Automotive; Tires
The diameter of a tyre rim, given in nearest whole numbers (e.g. 15 in.).
Steering system
Automotive; Tires
The entire mechanism that allows the driver to guide and direct the vehicle; includes the steering wheel, steering column, steering gear, linkages, and wheel supports.
Offset
Automotive; Tires
The offset of the rim is what locates the tire/wheel assembly in relation to the suspension. A wheel with zero offset has a mounting face that directly aligns to the wheel’s centerline.
Breakaway
Automotive; Tires
A term used to describe a loss of traction when negotiating a curve or when accelerating from a standing start. The tyres slide against, instead of grip, the road surface.
Camber
Automotive; Tires
A wheel’s inward or outward tilt from vertical, measured in degrees. The camber angle is adjusted to keep the outside tyres flat on the ground during a turn.
Camber thrust
Automotive; Tires
Side or lateral force generated when a tyre rolls with camber, which can add to or subtract from the side force a tyre generates.
Carbon black
Automotive; Tires
This is a reinforcing filler which, when incorporated into the tyre rubber compound, gives it a high resistance to wear.
