Multi-Piece and Single-Piece Rim Wheels - Introduction

A rim wheel is the component assembly of a wheel, tire, tube, and other components. There are two types of rim wheels:

Single-Piece Rim Wheels

Multi-Piece Rim Wheels.

A single-piece wheel is the component of the assembly used to hold the tire, form part of the air chamber (with tubeless tires), and provide the means of attachment of the assembly to the vehicle axle.

A multi-piece wheel is a vehicle wheel consisting of two or more parts, one of which is a side or locking ring that holds the tire and other components on the rim wheel by interlocking the components when the tire is inflated.

The standard does not apply to the servicing of rim wheels utilizing automobile tires or truck tires designated "light trucks (LT)."
