RIM AND WHEEL COMPONENTS.
General.
Sometimes the terms "wheel" and "rim," are used out of content even though there are major
differences. A wheel is not a rim and a rim is not a wheel. The following definitions will help you
understand the differences between these components.
(1)
Wheel.
Wheels are either a "disc wheel" type or "spoke wheel" type.
A disk wheel, which is
common with military vehicles, is a combination of a disc and rim and illustrated below. The disc is
permanently attached (usually welded) to the rim and attaches to the vehicle hub with studs and nuts. A
spoke wheel, does not have a rim permanently attached and consist of a hub and either 3, 5, or 6 spokes
with clamps which attach to demountable type rims.
(2)
Rim.
The rim is the part which supports the tire.
By definition the rim does not include the
disc portion of a wheel which mounts to the vehicle.
The rim is either single piece (usually for tubeless
tires) or
multi-piece for tube-type tires.
Multi-piece rims, depending on the type, will have a continuous
base assembly and a side ring or a side and lock ring.
A single piece rims is a continuous, one piece
assembly without side or lock rings.
