Make Sure Your Wheels Actually Bolt On
This is the most basic step in buying wheels — and the one people skip the most when they find a design they love.
Your bolt pattern determines whether a wheel will physically mount to your vehicle.
No amount of style matters if the wheels don’t bolt up.
Bolt pattern (also called PCD — Pitch Circle Diameter) is written as two numbers:
Example: 5x114.3
- 5 = number of lug nuts
- 114.3mm = diameter of the circle they form
Most vehicles use common patterns, but variations across manufacturers — and even between model years — mean you should never assume compatibility.
Measuring a 5-lug bolt pattern can also be tricky since you can't measure directly across the center of the wheel.
This calculator handles the math for you.
Just enter your measurements and we’ll confirm your exact bolt pattern.
While hub rings and spacers exist for fine adjustments, they cannot fix an incorrect bolt pattern.
Use the calculator first and make sure the wheels you want will actually mount to your vehicle.
