4x100 Bolt Pattern
A bolt pattern, or lug pattern, is a parameter that defines the number of lug holes in the wheel and the diameter of the circle (PCD, Pitch Circle Diameter) that the lug holes form. 4x100 bolt pattern, or 4x3.94 when converted to inches, indicates the wheel has 4 lug holes spaced evenly on a circle with a diameter of 100 millimeters or 3.94 inches. The 4x100 bolt pattern is common to Smart, Fiat, Scion, Mitsubishi and Mazda models.
The 4x100 bolt pattern is a common wheel fitting standard characterized by four lug holes spaced evenly in a 100mm diameter circle. This configuration is widely used across a variety of compact and subcompact vehicles, offering a balance of simplicity and structural integrity. The "4" in the designation indicates the number of lug holes in the wheel, while "100" refers to the diameter of the circle (in millimeters) that these holes form. This bolt pattern is pivotal for ensuring that wheels are properly aligned and securely attached to the vehicle's hub, contributing significantly to the vehicle's safety, performance, and ride quality. Manufacturers across the globe, especially those producing vehicles in the smaller size segments, favor the 4x100 layout due to its ease of manufacturing and widespread compatibility. Consequently, wheels with a 4x100 bolt pattern are highly interchangeable, offering drivers a broad selection of aftermarket options for customization and replacement, enhancing the vehicle's aesthetic appeal and potentially its performance characteristics.

4-Lug Pattern Torque Sequence
The lug bolt pattern torque sequence is a critical procedure designed to ensure that the wheel is mounted securely and uniformly on the vehicle's hub, preventing potential issues such as wheel vibration or hub damage. This sequence varies slightly depending on the number of lug bolts but always follows a pattern that promotes even distribution of force. When tightening lug nuts or bolts on a wheel with a 4-lug pattern, follow the torque sequence shown below to ensure even and secure tightening. The process usually involves multiple passes: initially tightening bolts to a lower torque setting to seat the wheel properly, followed by final tightening to the manufacturer's recommended torque specification using a calibrated torque wrench. Adhering to this sequence and using the correct torque ensures the wheel is balanced and securely attached, reducing the risk of brake rotor warping and ensuring the safety of the vehicle.
