The configuration of lug nuts on the wheel hub of a 2011 Cadillac SRX follows a specific arrangement. This arrangement, often expressed numerically, dictates the diameter of the circle formed by the centers of the lug holes and the number of lug holes present. For example, a specification might be described as 5×120, indicating five lug holes on a circle with a 120mm diameter. This measurement is critical for ensuring wheel compatibility.
Adherence to the correct specification is paramount for vehicle safety and performance. Utilizing wheels with an incorrect configuration can lead to improper wheel seating, potentially causing vibrations, lug nut failure, and, in extreme cases, wheel detachment. Historically, variations in this specification have existed across different vehicle makes and models, necessitating careful verification before wheel installation. Understanding the proper specification ensures the secure and balanced mounting of wheels.
