Why this page exists

Wheel fitment gets easier to discuss when lug count and bolt-circle diameter are shown in the common pattern format instead of being read as separate numbers. This calculator helps visitors format a wheel bolt pattern such as 5x114.3 from simple bolt-pattern inputs.

Wheel bolt pattern calculator

Format a wheel bolt pattern from lug count and bolt-circle diameter with an optional unit choice.

Result

5x114.3

Estimated wheel bolt pattern format based on lug count and the bolt-circle diameter entered.

Bolt pattern format5x114.3

Bolt-circle diameter used114.3 mm

Equivalent in millimeters114.3 mm

Equivalent in inches4.500 in

5 lugs with a 114.3 mm bolt-circle diameter is commonly written as 5x114.3.
The pattern label is only a quick fitment reference, so center bore, wheel offset, and brake clearance still need to be checked separately.
Use the result as a simple formatting and reference tool when you want the common pattern label shown clearly.

This is a simple bolt-pattern formatting tool. Real wheel fitment still depends on stud size, center bore, offset, brake clearance, and the exact pattern specification for the vehicle.

Planning note

How it works

What the calculator is doing

Choose the lug count and enter the bolt-circle diameter.

Select whether the diameter is being entered in millimeters or inches.

The calculator formats the result in the common bolt-pattern style and shows the equivalent measurement in the other unit.

Understanding your result

This is a simple bolt-pattern reference tool. It helps with the common pattern label, but real fitment still depends on center bore, wheel offset, stud size, and brake or suspension clearance.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Format a common wheel pattern clearly

A quick label like 5x114.3 can be easier to compare than separate lug-count and diameter notes.

Switch between millimeters and inches

The equivalent-unit view can help when wheel specs and vehicle specs are listed in different formats.

Use it with other wheel tools

Bolt-pattern checks often make more sense beside wheel offset, wheel spacer, and tire-size comparisons.

FAQ

Common questions

What does a pattern like 5x114.3 mean?

It means the wheel has 5 lugs and a 114.3 mm bolt-circle diameter.

Does matching the bolt pattern guarantee fitment?

No. Bolt pattern is only one part of fitment. Offset, center bore, stud size, brake clearance, and tire clearance still matter too.

Why show both millimeters and inches?

Wheel specs and vehicle specs are sometimes listed in different unit systems, so seeing both formats can make comparisons faster.
