What Does 4x100 Mean on Wheels?

Decoding Wheel Fitment: What Does a 4x100 Bolt Pattern Really Mean?

When shopping for aftermarket wheels, understanding fitment terminology is essential to ensuring your new rims bolt up safely and correctly. Among the most popular configurations in the automotive enthusiast community, the 4x100 bolt pattern remains a gold standard for compact cars and track builds.

How the 4x100 Bolt Pattern Works

The code 4x100 defines two precise measurements of a wheel's Pitch Circle Diameter (PCD), which specifies how lug holes are arranged around the hub center:

• 4 (Lug Count): Indicates the wheel has four lug holes designed to accept wheel studs or lug bolts.
• 100 (Pitch Circle Diameter): Measures the diameter of the imaginary circle passing through the center of all four bolt holes, equal to exactly 100 millimeters (or roughly 3.94 inches).

Because 4-lug wheels have symmetrical spacing, measuring a 4x100 pattern is simple: place a tape measure or digital caliper directly from the center of one lug hole straight across to the center of the opposite lug hole. An exact match is a must - forcing a mismatched bolt pattern like 4x108 or 4x114.3 onto a 4x100 hub causes severe wheel vibration, uneven lug torque, and unsafe driving conditions.
