The dimensional configuration of the wheel mounting holes on a vehicle is a critical specification. For the 2014 Acura MDX, this specification is 5x120mm. This denotes a five-lug configuration, where five bolts or studs secure the wheel to the vehicle’s hub. The “120mm” indicates the diameter of the circle on which these five bolts are positioned, measured in millimeters. Using wheels with an incorrect measurement can lead to wheel detachment or damage to vehicle components.
Adherence to the correct wheel mounting specification is paramount for vehicle safety and performance. Using the appropriate wheel ensures proper load distribution and secure attachment, preventing vibrations, premature wear on bearings and suspension components, and potential wheel failure. Historically, consistent configurations have simplified wheel selection and compatibility across models and generations of vehicles. Furthermore, the proper wheel mounting configuration affects the vehicle’s overall handling and stability, contributing to a safer driving experience.
