Understanding wheel specifics is crucial when replacing damaged rims, switching to off-road options, or upgrading to aftermarket wheels. This guide focuses on wheel bolt patterns, which are essential in ensuring wheel compatibility with the vehicle. Here, you will explore the specifics, complexities, and measuring techniques of wheel bolt patterns, helping you find answers to the most common wheel-related concerns.
What Is a Wheel Bolt Pattern?
A wheel bolt pattern, also known as a lug pattern, is the arrangement of the lug holes in the center of a wheel. The wheel bolt pattern is expressed in a two-number system showing the number of bolts the wheel has and the diameter of the circle formed by the centers of the bolt holes. For example, a 5 x 4.5 bolt pattern wheel has 5 bolt holes whose circle measures 4.5 inches in diameter. The wheel bolt pattern must match the vehicle hub to ensure a secure and safe fit.
Let's compare the following vehicles: a Ford Mustang with a 5 x 4.5 bolt pattern and a Jeep Wrangler with a 5 x 127 bolt pattern. Both of them have 5-lug wheels. But because of the bolt circle diameter difference, their wheels are incompatible without adapters. This example shows how important is for drivers to know their specific bolt pattern.
Types of Wheel Bolt Patterns
There are three main types of wheel bolt patterns: even bolt patterns, odd bolt patterns, and specialized bolt patterns. Even bolt options can be 4-bolt and 6-bolt patterns. Odd bolt wheel options include 5-bolt patterns with several diameter variations (5 x 4.5, 5 x 127, 5 x 120, 5 x 115...). Specialized bolt patterns refer to unique configurations such as 8-bolt patterns (heavy-duty trucks like the Ford F-250 or Ram 2500) and multi-bolt patterns (e.g., 5 x 114.3 and 5 x 120 combined).
What Are the 4 Bolt Patterns?
A 4-lug pattern is the arrangement of 4 bolts/lugs on a wheel in a circular/cross pattern. The variable number following the "4" expresses the circle's diameter formed by these bolts (e.g., 4 x 4.25, 4 x 4.5, etc...). The diameter is usually measured in inches and converted to millimeters if needed as follows:

What Are the 5 Bolt Patterns?
A 5-lug pattern refers to the odd arrangement of 5 bolts in the center of a wheel in a circular pattern. The number following "5" shows the diameter of the circle these 5 bolts form (e.g., 5 x 5, 5 x 5.5, 5 x 6.5, etc...). The diameter is mostly expressed in inches and can be converted into millimeters as follows:

What Are the 6-Bolt Patterns?
A 6-lug pattern is the arrangement of the 6 bolts in the center of the wheel. The "6" is followed by a second number showing the diameter of the circle these lugs form. For example, the 6 x 4.5" bolt pattern represents 6 lugs forming an imaginary circle with a diameter of 4.5 inches. The 6-bolt pattern inches can be expressed in millimeters as follows:

What Are the 8-Bolt Patterns?
An 8-bolt wheel pattern means the center of a wheel has 8 holes for 8 lugs. The number following the "8" shows the diameter of the circle that these eight lugs/bolts form. The diameter is expressed in inches or millimeters as follows:

How to Measure a Wheel Bolt Pattern
Use a caliper or ruler to measure a wheel bolt pattern by applying it from the center of one lug hole to the center of the opposite lug hole for wheels with an even number of bolts. That is how you find out the measurement of the bolt circle diameter. Consider the distance from the center of one lug hole to the outer edge of the farthest lug hole, in case of an odd number of wheel bolts. Use the bolt pattern conversion chart example below to find out the diameter of the bolt circle:

Common Bolt Patterns and Their Applications
The following bolt patterns of some popular configurations can be useful in finding the right wheels for your vehicle:
For example, the 5 x 4.5 (114.3 mm) is typically suitable for sedans and light-duty applications like Toyota RAV 4 and Ford Explorer. The 5 x 127 (5 inches) is generally compatible with rugged terrain and off-road vehicles like Jeep Wranglers. The larger the bolt pattern diameter, the higher the vehicle stability.

Consider the bolt pattern chart below to simplify your search for compatible wheels. For example, a driver replacing wheels on a Jeep Cherokee (Jeep vehicle category) can use the chart to identify the 5 x 127 bolt pattern as a compatible fit:
How to Find Bolt Pattern on Rims
To find the bolt pattern on rims, look for the stamped or engraved details on the back or inside the rim. Markings like “5 x 4.5” or “5 x 127” tell you the number of wheel bolts and the diameter of the circle they form. For example, identifying the 5 x 115 bolt pattern on aftermarket wheels makes it a secure fit for a Dodge Charger.
