What is the 6x139 lug pattern?
The 6x139 bolt pattern, also written as 6x139.7 mm, means six lug holes arranged on a circle that is 139.7 millimeters in diameter (about 5.5 inches). It is a common fitment for certain trucks and SUVs and is a key factor in wheel compatibility.
In more detail, the bolt pattern describes not only how many lug holes a wheel requires, but also the diameter of the circle those holes form (the bolt circle). When shopping for wheels, you must also consider the center bore size, the wheel offset/backspacing, and the type of lug nuts or studs used. While 6x139.7 is a familiar footprint for some vehicle platforms, exact fit can vary by model year and trim, so always verify with the vehicle’s specs and the wheel manufacturer.
Understanding the 6x139 pattern
Here are the essential characteristics you should know about the 6x139 pattern and how it relates to wheel fitment:
Common characteristics and implications
- Number of lug holes: 6
- Bolt circle diameter (PCD): 139.7 mm (approximately 5.50 inches)
- Center bore and hub compatibility: varies by vehicle; some wheels are hub-centric while others are lug-centric
- Application: frequently used on certain heavy-duty trucks and SUVs, and widely represented in aftermarket wheel options
- Wheel suitability: ensure the wheel’s offset, backspacing, and load rating match your vehicle’s specifications
Understanding these factors helps prevent fitment issues such as improper seating, brake interference, or hub misalignment. Always confirm the exact specifications for your vehicle and the wheel you intend to install.
Common usage by vehicle type
This bolt pattern is most often associated with heavier-duty applications and aftermarket conversions rather than mainstream passenger cars. It appears on a range of full-size trucks and SUVs across various brands, and its popularity stems from compatibility with many aftermarket wheels designed for trucks and off-road setups.
- Heavy-duty and full-size trucks (and some SUVs) that require six lugs on a 5.5-inch bolt circle
- Vehicles used for towing, off-roading, and commercial applications where aftermarket wheels are common
- Aftermarket wheels marketed specifically for 6x139.7 and compatible with compatible hubs/centers
Because bolt patterns can vary by year and trim, it is essential to verify the exact specification for your vehicle model before purchasing wheels or adapters.
How to verify compatibility
To ensure a wheel with a 6x139 bolt pattern fits your vehicle, follow these steps:
- Check the vehicle’s owner’s manual or the door jamb placard for the wheel bolt pattern specification (6x139.7 mm or 6x5.50 in).
- Measure the bolt circle diameter yourself if needed: measure from the center of one lug hole to the center of the opposite lug hole across the wheel and confirm it is about 139.7 mm (5.50 inches).
- Confirm center bore size and whether the wheel is hub-centric for your hub; ensure the bore matches or use appropriate spacers/adapters if necessary.
- Check offset and backspacing to ensure brake caliper clearance, fender clearance, and suspension compatibility.
- Consult the wheel manufacturer or a qualified installer if you’re unsure, especially when combining aftermarket wheels with your vehicle’s brakes and suspension.
Following these steps reduces the risk of misfit wheels and helps ensure safe, reliable installation.
Additional considerations
Some vehicles may use the same 6x139.7 pattern but require different center bores or offset values. Always verify all dimensions—pattern, bore, offset, and lug hardware—with official specifications or a trusted professional before changing wheels.
Summary
The 6x139 bolt pattern denotes six lug holes arranged on a 139.7 mm (5.5 inch) circle and is common among certain trucks and SUVs, particularly in heavy-duty and aftermarket wheel applications. To ensure a proper fit, verify the pattern, center bore, offset, and lug hardware for your specific vehicle and wheel combination, and consult a wheel specialist if in doubt.
Is 6x139 7 the same as 6x5 5 bolt pattern?
Yes, a 6x5.5 bolt pattern is the same as a 6x139.7 bolt pattern because they are just different ways of measuring the same lug pattern. "6x5.5" uses standard imperial measurements, while "6x139.7" uses metric, but both describe a six-lug wheel with a bolt circle diameter of 139.7 millimeters.
- Standard vs. Metric: The difference in notation is due to the measurement system used.
- Interchangeable: Wheels with either notation will fit the same vehicle.
- Common Use: This bolt pattern is very common on many trucks and SUVs, such as those from Chevrolet, GMC, and Toyota.
- Important Note: While the bolt pattern is the same, always confirm that the wheel's center bore (the hole in the middle) is compatible with your vehicle's hub to avoid vibration or safety issues.
What vehicles use the 6x139 bolt pattern?
Vehicles with a 6x139.7 bolt pattern include a wide range of trucks and SUVs from various manufacturers, such as Chevrolet (Silverado 1500), GMC (Sierra 1500), Toyota (Tacoma, 4Runner, Tundra), Nissan (Titan), Ford (Bronco, older F-150s), and Lexus. This bolt pattern is very common and is also referred to as 6x5.5.
Chevrolet and GMC
- Chevrolet Silverado 1500: Most models from 1999 to the present
- GMC Sierra 1500: Similar to the Silverado, most models are a 6x139.7 pattern
- Chevrolet Tahoe/Suburban: Many generations have this pattern
- GMC Yukon: Many models have this pattern
Toyota and Lexus
- Toyota Tacoma: Many models from 1996-2020 have this pattern
- Toyota 4Runner: Many models are compatible with this pattern
- Toyota Tundra: Models from 1999-2006 use this bolt pattern
- Toyota Sequoia: Many models fit this pattern
- Toyota Mini Truck: Some older models from 1979-1995 use this pattern
- Lexus: Some models, such as the LX and GX, use this pattern
Nissan
- Nissan Titan: Some models have a 6x139.7 bolt pattern
- Nissan Armada: Some models use this pattern
Ford
- Ford Bronco: The new Bronco has a 6x139.7 bolt pattern
- Older Ford F-150: While many F-150s are 6x135, some models, especially older ones, may be 6x139.7
- Ford Ranger: Some models use this pattern
Other makes

Is 6x135 bolt pattern the same as 6x139?
The answer is yes, as long as you use 6×135 to 6×139.7 adapters. The bolt pattern of the new Ford Bronco is 6×139.7mm while the lug pattern of a F150 is 6x135mm. It is hard to install F150 wheels on a Ford Bronco directly. With a 6×135 to 6×139.7 adapter, the Bronco and F150 wheels can be interchangeable.
Is the Ford 6-lug pattern the same as the Chevy?
No, the most common Ford 6-lug pattern ($6 \times 135$mm) is different from the most common Chevy 6-lug pattern ($6 \times 139.7$mm), though some specific models may match. For example, a Ford F-150 uses a $6 \times 135$mm bolt pattern, while a Chevy Silverado typically uses a $6 \times 139.7$mm pattern. There are some exceptions, such as the Ford Ranger and newer Ford Broncos which use the $6 \times 139.7$mm pattern, making them interchangeable with certain Chevy models.
Different bolt patterns
- Ford F-150: The most common pattern for recent models is $6 \times 135$mm.
- Chevy Silverado: The standard pattern is $6 \times 139.7$mm (also known as 6×5.56 cross 5.56×5.5).
Exceptions and similarities
- Ford Ranger: Uses the same $6 \times 139.7$mm pattern as Chevy, but the center bore may be different and require adapters.
- Newer Ford Bronco: Uses the $6 \times 139.7$mm pattern, making its wheels interchangeable with Chevy models.
- Aftermarket wheels: Often have a universal design with a dual bolt pattern that fits both $6 \times 135$mm and $6 \times 139.7$mm hubs.
What to check
- Always confirm the specific bolt pattern for both your vehicle and the wheels you are considering.
- Check that the center bore (the hole in the center of the wheel) is the correct size for your vehicle's hub, or be prepared to use a hub-centric ring.
- Verify that the wheel will not interfere with brake calipers or other suspension components.
