Bolt Pattern Calculator — Determine Your Wheel Bolt Pattern

Bolt Pattern Calculator

Calculate your vehicle’s wheel bolt pattern (PCD) with our comprehensive calculator. Determine lug pattern, bolt circle diameter, and wheel fitment specifications for proper installation.

Step 1: Bolt Pattern Specifications

100 mm

Understanding Bolt Patterns

Bolt pattern (PCD – Pitch Circle Diameter) is expressed as number of bolts x diameter of bolt circle. Example: 5×114.3 means 5 bolts with 114.3mm diameter circle.

Step 2: Vehicle & Wheel Parameters

About Wheel Fitment

Center bore must match vehicle hub for proper centering. Wheel offset affects how wheels sit relative to suspension and body. Always verify specifications with manufacturer.

Bolt Pattern Formula

For even bolt patterns (4, 6, 8): Measure center-to-center distance between opposite bolts. For 5-bolt patterns: Measure from bolt center to farthest point on opposite imaginary circle.
