How to Measure a Wheel Bolt Pattern: Step-by-Step Guide

March 6, 2025 EV Powered

Knowing your wheel bolt pattern is a must if you’re replacing stock rims, buying aftermarket wheels, or just making sure new rims will fit your ride.

In this guide, you’ll learn exactly how to measure a wheel bolt pattern—whether you have 4, 5, 6, or 8 lug nuts—so you can avoid costly mistakes and keep your vehicle safe and stylish.

What Is a Wheel Bolt Pattern?

A wheel bolt pattern (sometimes called a lug pattern) shows how lug holes are arranged on a wheel. Typically, it’s written as two numbers:

The number of lug holes (4, 5, 6, or 8).
The bolt circle diameter (BCD) in millimeters (e.g., 100 mm, 114.3 mm, 139.7 mm).

For example, 5×114.3 means there are 5 lug holes, and the distance across the circle that runs through the center of each hole is 114.3 mm.

Tools You’ll Need

Measuring Tape: Ideally metric (millimeters).
Pen or Pencil and Paper: To write down measurements.
Straightedge (Optional): Helps with more precise alignment.
Caliper (Optional): Useful if you need ultra-accurate measurements.

How to Measure a Wheel Bolt Pattern: Even vs. Odd Lug Counts

Measuring 4-Lug and 6-Lug Patterns (Even)

If you have an even number of lug holes (4, 6, or 8), you’ll measure from the center of one hole straight across to the center of the hole directly opposite.

Pick Opposite Holes: Choose your starting hole, then find the hole directly across.
Center-to-Center: Run the measuring tape through both hole centers.
Convert to Millimeters: If you measure in inches, remember 1 inch = 25.4 mm.
Record the Pattern: For instance, if the measurement is 100 mm for a 4-lug wheel, your pattern is 4×100.

Measuring a 5-Lug Pattern (Odd)

For 5 lugs, it’s trickier because there’s no direct opposite hole:

Choose the First Lug Hole: Label it “Hole A.”
Skip One Hole, Move to the Third: From Hole A, count one hole over, then go to the next one.
Measure Center to Outer Edge: Align your tape at the center of Hole A and measure to the far edge (or center-to-center, depending on the reference chart) of the third hole.
Convert and Note: Common examples include 5×114.3 (about 5×4.5 inches).

Pro Tip: Always check a trusted chart or manufacturer’s specs if you’re unsure.

Enhance Your Classic Look with LA Wire wheels

If you love timeless designs, LA Wire wheels provide that vintage, spoke-style appearance many car enthusiasts adore. But even with classic wire wheels, measuring your bolt pattern is critical. By taking the time to confirm your lug spacing, you’ll ensure that your LA Wire wheels fit securely and perform at their best. Plus, you’ll avoid the frustration of ordering wheels that don’t match your bolt circle diameter—saving both time and money.

Tips for Accurate Measurements

Go Metric: Bolt patterns are noted in millimeters, so if your tape measures inches, convert (1 inch = 25.4 mm).
Double-Check: Measure more than once to avoid simple mistakes.
Remove Obstructions: Things like hubcaps or center caps can block accurate lug hole measurements.
Bolt Pattern Gauge: If you measure wheel bolt patterns often, a specialized gauge is a smart investment.

Common Bolt Pattern Reference Chart

Lug Count	Common Patterns (mm)	Inch Conversion	Vehicle Examples
4 Lug	4×100, 4×114.3	4×3.94″, 4×4.5″	Honda Civics, Some Nissan Models
5 Lug	5×114.3, 5×100, 5×120	5×4.5″, 5×3.94″, 5×4.72″	Toyota Camry, BMW, Subaru, Ford
6 Lug	6×139.7, 6×135	6×5.5″, 6×5.3″	Trucks & SUVs (Chevy, GMC, Toyota)
8 Lug	8×165.1, 8×170	8×6.5″, 8×6.69″	Heavy-duty trucks (Chevy, Ford)

Note: Always verify for your specific year, make, and model.

Elevate Your Vehicle with AC Wheels

Ready for a modern twist? AC Wheels are built with cutting-edge designs and strong materials that enhance both style and durability. However, even the most cutting-edge rims won’t fit if your bolt pattern is off. Before ordering AC Wheels, follow the measurement steps above—especially if you have a 5-lug setup that’s more prone to error. Taking a few extra minutes to measure ensures your vehicle will roll smoothly without any wobble or risk of damage.

How to Find Bolt Pattern on a Rim

If you have a separate rim (no tire attached) and need to confirm its bolt pattern:

Check for Markings: Some rims have numbers like “5×114.3” stamped on the back or near the center.
Look at the Box or Label: New wheels often list the pattern on the box or invoice.
Manual Measurement: When all else fails, use the same method described above.

Make a Statement with forgiato rims

For those seeking a top-shelf, luxurious upgrade, forgiato rims are a perfect choice. Renowned for their high-end craftsmanship and attention to detail, Forgiato wheels can transform any car into a head-turner. But like any premium wheel, they need the right bolt pattern to mount properly. Once you’ve confirmed your lug spacing, you’ll be ready to show off those new Forgiatos with complete confidence—knowing they’re both stylish and safely secured.

FAQs: Checking Lug Pattern & More

Q1: Can I measure in inches if I don’t have a metric tape?

Absolutely. Measure in inches and multiply by 25.4 to get millimeters.

Q2: Does a vehicle’s bolt pattern change over time?

Not usually—your car’s bolt pattern stays the same unless you swap out major parts like axles or hubs.

Q3: What if my numbers don’t match typical patterns?

Double-check your process. Some less common vehicles might have rare patterns, so consult your manual or a wheel professional.

Q4: Is the center bore the same as the bolt pattern?

No. The center bore is the hole at the center of the wheel, while the bolt pattern is about lug spacing. Both matter for fitment.

Q5: Can adapters change my bolt pattern?

Yes, adapters can convert one pattern to another, but always confirm they’re safe and meet load requirements.

Final Thoughts

Learning how to measure a wheel bolt pattern is a core skill for anyone customizing or replacing wheels. Here’s what to remember:

4-Lug or 6-Lug: Measure straight across center-to-center.
5-Lug: Measure from the center of one hole to the far edge of the hole two spots away.
Double-Check: Verify your numbers or use a bolt pattern gauge for best results.

Whether you’re installing LA Wire wheels, AC Wheels, or going for luxury with forgiato rims, proper bolt pattern measurements ensure a smooth, secure fit every time. Happy wrenching—and enjoy your newly outfitted ride!
