5x100 Quick Facts
What Does 5x100 Mean?
The first number tells you how many wheel studs or lug holes the pattern uses. The second number is the pitch circle diameter (PCD): the diameter of the imaginary circle that passes through the centers of those studs.

How to Measure the 5x100 Bolt Pattern
For a 5-lug pattern, a bolt-circle template or manufacturer specification is the most reliable method. A common field method measures from the center of one stud toward the outer edge of the farthest stud, but verify the final PCD before buying wheels.
Because small measurement errors can lead to the wrong wheel, use the vehicle or wheel manufacturer's specification whenever possible.
Does a Matching 5x100 Bolt Pattern Guarantee Wheel Fitment?
No. Bolt pattern is only one part of wheel compatibility. You must also check center bore, wheel diameter, wheel width, offset/backspacing, brake clearance, lug-seat/thread hardware and load capacity before installing a wheel.
Check Your Vehicle Before Choosing Wheels
Use the vehicle fitment finder for vehicle-specific specifications, and use the wheel offset calculator to understand position and clearance changes.
