The arrangement of lug nuts on a wheel hub for attachment is a crucial specification for vehicle compatibility. This specification is often represented in a tabular format, providing information necessary for ensuring proper wheel fitment. For a particular make and model of automobile, such as those produced by Cadillac, this information is essential for selecting appropriate wheels. An example would be a representation indicating a 5×115 configuration, signifying five lug nuts positioned on a circle with a 115mm diameter.
Accurate wheel fitment is paramount for vehicle safety and performance. Utilizing the correct wheel configuration prevents stress on the wheel studs and ensures proper load distribution. Historically, manufacturers have employed various arrangements, necessitating specific lookup resources for determining compatibility. This specification detail is also critical when considering aftermarket wheel upgrades or replacements, ensuring the new wheels are compatible with the vehicle’s hub.
