Your Bolt Pattern

5×114.3

This means 5 bolts on a 114.3 mm diameter circle. Wheels must match this pattern exactly to fit.

Frequently Asked Questions

Q

How do you measure a 4, 5, or 6 lug bolt pattern?

For even-numbered lugs (4, 6, 8), measure center-to-center across opposite bolts — that distance is your PCD. For 5-lug patterns, measure from the center of one bolt to the far edge of the bolt directly across, or measure between adjacent bolts and use PCD = distance / sin(36°). The bolt pattern is expressed as lugs × PCD (e.g., 5×114.3).

  • 4-lug: measure diagonally between opposite bolt centers
  • 5-lug: measure center of one bolt to far edge of the opposite bolt
  • 6-lug: measure diagonally between opposite bolt centers
  • Use millimeters for accuracy—even a 1mm error can mean the wrong fitment
  • A bolt pattern gauge tool ($10–20) gives precise readings

Q

What does 5x114.3 mean and what vehicles use it?

5×114.3 means 5 lug nuts on a circle with a 114.3 mm diameter (pitch circle diameter or PCD). This is one of the most common bolt patterns, used by Honda, Toyota, Nissan, Hyundai, Ford (some models), and many others.

  • First number (5) is the lug count—how many bolts hold the wheel
  • Second number (114.3) is the PCD in millimeters—the bolt circle diameter
  • 5×114.3 is equivalent to 5×4.5" (same pattern in imperial)
  • Both the lug count AND PCD must match for a wheel to fit
  • Hub bore (center hole size) is a separate measurement that also must match or use hub-centric rings
Q

Can you put wheels with a different bolt pattern on your car?

No. Even 1–2 mm of PCD difference means the lug nuts won’t seat properly, causing vibration, uneven torque, and potential wheel detachment at speed. Never force a wheel onto a different bolt pattern. Bolt pattern adapters exist but add weight and reduce reliability.

  • A 1 mm PCD mismatch causes 0.5 mm bolt misalignment per lug
  • Misaligned lugs create vibration and can loosen over time
  • Bolt pattern adapters add 15–25 mm of width offset and 5–10 lbs of weight
  • Adapters are banned in some motorsport organizations and may void warranties
  • Always verify PCD, hub bore, offset, and lug type before purchasing wheels
Q

How do you calculate PCD from the distance between adjacent bolts?

PCD can be calculated from the distance between adjacent bolts using geometry. For a 5-bolt wheel: PCD = adjacent bolt distance / sin(36°) = distance / 0.5878. For 4-bolt: PCD = distance / sin(45°). This calculator handles the trigonometry automatically.

  • 4-bolt: PCD = adjacent distance × 1.4142 (divide by sin 45°)
  • 5-bolt: PCD = adjacent distance × 1.7013 (divide by sin 36°)
  • 6-bolt: PCD = adjacent distance × 2.0 (divide by sin 30°)
  • Measuring between adjacent bolts is easier than across on 5-lug wheels
  • Always double-check by measuring a second pair of adjacent bolts

Example Calculations

15-Lug Wheel, Adjacent Measurement

Inputs

Number of Lugs5
Adjacent Bolt Distance67.1 mm

Result

Bolt Pattern (PCD)5×114.3 mm
PCD in Inches4.5"
Common VehiclesHonda Civic, Toyota Camry, Nissan Altima

PCD = 67.1 / sin(36°) = 67.1 / 0.5878 = 114.17 mm, which rounds to the standard 114.3 mm pattern. This is 5×4.5" in imperial.

24-Lug Wheel, Opposite Measurement

Inputs

Number of Lugs4
Opposite Bolt Distance100 mm

Result

Bolt Pattern (PCD)4×100 mm
PCD in Inches3.94"
Common VehiclesHonda Fit, Mazda Miata, Hyundai Accent

For 4-lug wheels, PCD is simply the distance between opposite bolts: 100 mm. This is one of the most common small-car bolt patterns.

36-Lug Truck Wheel

Inputs

Number of Lugs6
Opposite Bolt Distance139.7 mm

Result

Bolt Pattern (PCD)6×139.7 mm
PCD in Inches5.5"
Common VehiclesToyota Tacoma, Chevy Silverado 1500, Ford F-150 (pre-2004)

6×139.7 (6×5.5") is the most common 6-lug truck pattern, used across most half-ton trucks and SUVs from Japanese and some American manufacturers.

Formulas Used

PCD from Adjacent Bolt Distance

PCD = d / sin(180° / n)

Calculates the pitch circle diameter from the center-to-center distance between two adjacent bolt holes.

Where:

d= Center-to-center distance between two adjacent bolt holes in mm
n= Number of bolt holes (4, 5, 6, or 8)

PCD from Opposite Bolt Distance (Even Lugs)

PCD = D (direct measurement)

For even-numbered bolt patterns, PCD equals the center-to-center distance between opposite bolts.

Where:

D= Center-to-center distance between opposite bolts in mm

Understanding Wheel Bolt Patterns

The bolt pattern (also called lug pattern or PCD) is the arrangement of lug holes on a wheel. It determines which wheels can physically bolt onto your vehicle. Getting the wrong pattern means the wheel simply won’t fit.

Every bolt pattern has two numbers: the lug count and the pitch circle diameter (PCD). The PCD is the diameter of the imaginary circle passing through the center of all bolt holes. Common patterns include 5×114.3, 5×120, 4×100, and 6×139.7.

This calculator determines your PCD from bolt measurements, checks compatibility between different wheels and vehicles, and shows which vehicles share your bolt pattern. Always verify offset and hub bore alongside bolt pattern for proper fitment.
