The configuration of the wheel fasteners on a Toyota Highlander defines the vehicle’s wheel mounting specification. This arrangement, typically described using two numbers the number of bolts or studs and the diameter of the circle they form is a critical factor for wheel compatibility. For instance, a “5×114.3” designation indicates five fasteners positioned on a circle with a diameter of 114.3 millimeters.
Correct wheel fitment ensures safe and reliable vehicle operation. Using wheels with an incorrect specification can lead to wheel detachment, damage to the vehicle’s hubs and suspension components, and potentially, accidents. Historically, maintaining standardized measurements has simplified wheel selection and compatibility across various models and generations. Accurate specification knowledge prevents costly errors and maintains the structural integrity of the vehicle.
