Bolt patterns determine which wheels can be safely mounted on your vehicle. This simple combination of numbers contains crucial information about wheel compatibility and proper fitment.
The bolt pattern consists of two essential numbers that define wheel fitment. The first number (5) indicates how many lug holes or studs your wheel has. The second number (5.5) measures the diameter of the imaginary circle formed by the centers of these lug holes, also known as the bolt circle diameter or pitch circle diameter (PCD).
Measuring odd-numbered lug patterns like 5x5.5 requires specific techniques. Even-numbered patterns allow direct measurement across opposing lugs, but 5-lug patterns require measuring from the center of one lug to the outer edge of an opposite lug. This is because the lugs are not directly across from one another in a 5-lug configuration.
You may encounter different terms like "bolt pattern," "lug pattern," or "PCD" used interchangeably. These all refer to the same measurement - the arrangement and spacing of the lug holes that secure your wheel to the vehicle.
The 5x5 and 5x5.5 patterns may look similar, but they have significant differences in dimensions and vehicle applications. The 5x5 pattern (also called 5x127mm) features five lugs arranged in a circle with a 5-inch diameter, while the 5x5.5 pattern has five lugs in a 5.5-inch diameter circle.
This half-inch difference is critical for proper fitment. The 5x5 pattern appears commonly on Jeep Wranglers, Grand Cherokees, and Gladiators, providing enhanced stability and strength compared to smaller patterns like 4x100mm. The 5x5.5 pattern appears frequently on older Ram trucks, the RAM Classic, some older F-150s, and older 4x2 Tacomas (non-PreRunners).
Ford vehicles historically used two main five-lug patterns. The 5x5.5-inch bolt pattern (the "large Ford" pattern) appeared on early Ford passenger cars before becoming exclusive to Ford trucks. The smaller 5x4.5-inch pattern (the "small Ford" pattern) appeared on vehicles like the Ford Fairlane and Mustang.
Early Chrysler full-size and luxury sedans also utilized the 5x5.5-inch pattern before transitioning to smaller configurations.
Bolt patterns are expressed using both imperial (inches) and metric (millimeters) measurements globally. The 5x5.5 bolt pattern equals 5x139.7mm in the metric system. This dual notation serves different markets - the U.S. and Canada typically use the inch measurement (5x5.5), while Europe and Asia generally prefer the millimeter equivalent (5x139.7mm).
Converting between these systems is straightforward: 1 inch equals 25.4 millimeters. Therefore, 5.5 inches multiplied by 25.4 equals 139.7mm. This conversion is essential when shopping for wheels internationally or when manufacturer specifications list only one measurement system.
The 5x5.5 (or 5x139.7mm) bolt pattern is known for its strength and reliability, making it particularly suitable for trucks, SUVs, and off-road vehicles. Its robust design effectively distributes the vehicle's weight across five points of contact, offering greater stability than four-lug designs.
Identifying your vehicle's correct bolt pattern ensures proper wheel fitment, safety, and performance. Whether you're upgrading your wheels for appearance or replacing damaged ones, understanding the 5x5.5 bolt pattern helps you make informed decisions about compatibility.

American truck manufacturers have relied on the 5x5.5 bolt pattern across numerous models for decades. Dodge Ram 1500 trucks manufactured before 2019 feature this robust pattern, alongside the versatile Dodge Dakota. Ford incorporated this configuration across multiple generations, including the F-100 and older F-150 models. The Ford F-150 Lightning Truck (1994-1996) also utilized this durable setup. International options include classic-generation Toyota Tacoma models equipped with this reliable pattern.
These trucks have become favorites among work-oriented drivers and weekend warriors who demand vehicles capable of handling significant loads without sacrificing performance. Performance Plus Tire offers an extensive selection of wheels compatible with these popular truck models.
Off-road enthusiasts know the value of the 5x5.5 bolt pattern for its proven durability on challenging terrain. Jeep has utilized this configuration extensively across multiple models, including the legendary CJ5, CJ7, and CJ8 Scrambler series. The pattern continued with Wrangler YJ and TJ models, plus the classic Wagoneer and select Jeep Gladiator trims.
The Ford Bronco (pre-1997) and Dodge Ramcharger also feature this dependable pattern. International manufacturers recognized its value too, with the Mitsubishi Montero, Suzuki Samurai (1986-1991), and Geo Tracker (1989-2004) all sporting the 5x5.5 configuration.
This bolt pattern has proven ideal for lifted builds, off-road setups, and towing applications due to its robust construction. Off-road enthusiasts continue choosing wheels with this pattern for their ability to withstand demanding conditions.
The 5x5.5 bolt pattern boasts a distinguished heritage spanning several decades. This configuration became common on American vehicles starting in the 1940s. Ford Broncos featured this pattern from 1966 through 1996, covering multiple generations of this iconic off-roader.
Military Jeeps from 1950-1966 utilized this reliable pattern, as did the Jeep J Series trucks produced between 1963-1968. American Motors incorporated the 5x5.5 pattern on all their 5-lug Jeeps manufactured from 1942 to 1986.
Beyond trucks and off-road vehicles, Chrysler used this pattern on their 8-cylinder models and wagons from 1946 to 1955, plus Imperial Special Heavy Duty models from 1954 to 1966. This widespread adoption across different vehicle types demonstrates the versatility and reliability of the 5x5.5 configuration.
Classic car enthusiasts and custom builders continue finding this bolt pattern relevant for vintage restorations, allowing them to maintain period correctness while potentially upgrading performance.
Getting accurate measurements on a 5x5.5 bolt pattern requires specific techniques since five-lug wheels don't have directly opposite lugs. Precise measurement prevents costly mistakes and ensures proper wheel fitment for your vehicle.
Accurate measurements start with the right tools:
A quality set of calipers (provides the most precise measurements)
A standard ruler or measuring tape (works for quick checks but less reliable)
A bolt pattern gage (the most accurate tool, specifically designed for this purpose)
Bolt pattern gages deliver the gold standard for accuracy. This specialty tool eliminates guesswork and provides exact measurements. However, bolt pattern gages are not widely available as they are specialty tools. Some companies offer precision bolt circle templates that simplify measuring common 5-lug patterns.
Five-lug patterns require special measurement techniques since they lack directly opposite lugs:
Count the lugs to confirm you have five (the first number in 5x5.5)
For direct measurement: Measure from the center of one lug to the imaginary outboard plane bridging the opposite two lugs
Alternative method: Measure from the center of one lug to the outer edge of the lug farthest away
Calculation method: Measure distance between adjacent bolt centers (X), then multiply by 1.701 to find the PCD
For 5x5.5 bolt pattern, the center-to-edge measurement should be approximately 3.25 inches
Measurements on 5-lug wheels are estimates unless you're using a specialized bolt pattern gage. Always consult a bolt pattern guide to confirm your findings, since several 5-bolt patterns have diameters very close to each other.
Even experienced mechanics make errors when measuring bolt patterns. Here are the most common pitfalls:
Measuring from incorrect points on lug holes instead of their centers
Assuming all wheels with the same lug count are interchangeable (spacing between lugs matters significantly)
Using imprecise tools, leading to inaccurate measurements
Mixing metric and imperial units (5x5.5 inches equals 5x139.7mm)
Taking only one measurement instead of readings at different points around the circle
Double-check your measurements by taking readings at different points around the bolt circle. Consistent results confirm accuracy, while variations indicate measurement errors. When in doubt, professional consultation is valuable, particularly with 5-lug patterns where precision is critical.
Wheel selection for your 5x5.5 vehicle involves more than just matching bolt patterns. The right wheels improve both performance and appearance while ensuring safety and proper fitment.
Multi-lug wheels offer versatility for vehicles with less common bolt patterns. These designs feature oval-shaped holes that accommodate multiple configurations, including 5x5.5. Uni-lug wheels use oval washers and shank-style lug nuts to center properly on different patterns.
This flexibility benefits owners who switch vehicles frequently or have uncommon bolt patterns. However, dedicated single-pattern wheels typically provide better centering and appearance.
Steel wheels deliver proven durability:
Superior resistance to cracking and bending
Better winter traction from added weight
