Understanding the 5 Lug Bolt Pattern
The 5 lug bolt pattern is crucial when replacing wheels on cars, SUVs, and trucks. It defines the arrangement of the five lug holes on a wheel and ensures proper fitment to the vehicle’s hub.
What is a Bolt Pattern?
A bolt pattern, also known as a lug pattern or bolt circle, specifies how many bolts or studs are used to secure a wheel to a vehicle’s hub and the diameter of the circle they form. Represented as two numbers (e.g., 5×4.5), the first indicates the number of lug holes or studs, while the second denotes the diameter of the imaginary circle passing through their centers, measured in inches or millimeters. Common configurations include 4-lug, 5-lug, 6-lug, and 8-lug patterns. For example, a 5×100 bolt pattern signifies a 5-lug arrangement with a 100mm diameter bolt circle. Correctly identifying your vehicle’s bolt pattern is essential for selecting compatible wheels, ensuring safe and secure installation.
How to Measure a 5 Lug Bolt Pattern Accurately
Accurate measurement is key to finding the correct wheel fit. For 5-lug patterns, measure from the top of one stud to the center of the opposite stud. Precision is paramount.
Tools Required for Measurement
To accurately measure a 5 lug bolt pattern, you’ll need a few essential tools. First, a precise measuring tool is indispensable; a digital caliper is highly recommended for its accuracy. A ruler or measuring tape can also work, but ensure it has clear, easy-to-read markings.
Next, you’ll need a pen and paper to record your measurements, or a digital notepad on a tablet or phone. Good lighting is also crucial to ensure you can clearly see the lug holes and measuring tool. If working in a dimly lit area, use a flashlight or work light.
Consider having a bolt pattern template on hand for quick verification. Finally, having access to a bolt pattern conversion chart (inches to metric) can be useful, especially if you encounter odd measurements. These tools will ensure you obtain precise and reliable measurements.
Step-by-Step Measurement Guide
Measuring a 5 lug bolt pattern requires precision. First, identify the correct points for measurement. On a 5-lug pattern, measure from the top edge of one stud to the center of the stud directly opposite it;
Use a caliper or ruler for this measurement, ensuring it’s as accurate as possible. Record the measurement. Repeat the measurement a few times to confirm consistency and accuracy. If the measurement is in inches and you suspect a metric pattern, convert it using a conversion chart.
Once you have the measurement, compare it to a bolt pattern guide to determine your vehicle’s bolt pattern. Remember that accuracy is crucial to ensure the correct fit.

Common 5 Lug Bolt Patterns
5 lug bolt patterns vary and are often dictated by vehicle type. Common sizes include 5x100mm, 5×114.3mm (5×4;5″), 5x120mm, 5×120.7mm (5×4.75″), 5x127mm (5×5″), 5x135mm, and 5×139.7mm (5×5.5″), each fitting specific vehicles.
Metric and Standard Measurements
Understanding the difference between metric and standard measurements is essential when dealing with 5 lug bolt patterns. The wheel bolt pattern, also known as the PCD (Pitch Circle Diameter), can be referred to in either standard or metric measurements, often dictated by the vehicle’s origin. Most older vehicles have bolt patterns referenced in standard units (e.g., 5×4.5 inches), while newer models often use metric (e.g., 5×114.3 mm).
It can be difficult to know if your wheel bolt pattern is metric or standard, especially if measurements yield odd values. If an inch measurement seems unusual, it may be a metric pattern and vice versa. Conversion charts are valuable to determine exact equivalents. Accuracy is paramount when measuring, and conversion tables help validate measurements.
5 Lug Bolt Pattern Conversion Chart (Inches to Metric)
Converting between inches and millimeters is essential for accurately identifying 5 lug bolt patterns. When measurements yield unusual values, it may be necessary to convert to the other system. This conversion chart will help determine the correct bolt pattern.
If you get an odd measurement in inches, the wheel may have a metric pattern; The same is true if you are measuring in millimeters. Below, the conversion chart lists common 5 lug bolt patterns and their metric equivalents. For example, 5 x 4.5 inches converts to 5 x 114.3 mm. Knowing these conversions is essential for selecting the correct wheels.
Vehicles with Common 5 Lug Bolt Patterns
Many cars and SUVs use 5 lug patterns, such as 5x100mm or 5×114.3mm. Some smaller trucks also utilize them. Knowing the specific pattern ensures proper wheel fitment.
Cars and SUVs
The 5x100mm bolt pattern is common among various car brands, including some Subaru models, older Volkswagens, and certain Toyota vehicles. The 5×114.3mm (or 5×4.5 inch) pattern is extensively used by Honda, Nissan, Mazda, and Ford, appearing on models like the Honda Civic, Nissan Altima, and Ford Mustang. Certain Jeep models and Dodge vehicles also feature this bolt pattern.
The 5x108mm pattern is frequently found on Volvo and some Ford models. The 5x115mm pattern is often seen on certain GM vehicles. It is crucial to verify the specific bolt pattern for your vehicle to ensure compatibility. Incorrectly fitting wheels can lead to safety issues and damage to the vehicle. Consult your vehicle’s manual or use a reliable bolt pattern guide to determine the correct specification. Online resources and wheel fitment tools can also assist in identifying the appropriate bolt pattern for your car or SUV.
