Is 6x139 7 the same as 6x5 5?
Yes. They describe the same wheel bolt pattern, just expressed in different units: six lug holes on a circle with a diameter of 139.7 millimeters, which is exactly 5.5 inches.
What the numbers mean
The bolt pattern is defined by two numbers: the number of lug holes and the diameter of the circle that passes through their centers. Metric notation uses millimeters, while imperial notation uses inches. When you convert 139.7 mm to inches, you get 5.5 inches, so 6x139.7 is the same as 6x5.5.
Where you’ll see these specs
These specs appear on wheel and vehicle documentation, purchase listings, and compatibility charts. Most modern trucks and SUVs list bolt patterns in either metric or imperial form.
Practical considerations for shoppers
Even if the bolt pattern matches, other wheel specs must also align for safe installation. Center bore, offset, width, and brake caliper clearance all matter. Always confirm compatibility with your vehicle maker or a trusted wheel retailer.
Key points to remember before listing:
- 6x139.7 mm means six lug holes on a 139.7 mm circle; this is exactly 5.5 inches.
- Both numbers describe the same pattern in different units; they are interchangeable in meaning.
- When swapping wheels, check center bore size to ensure a hub-centric fit and avoid vibrations.
- Offset and wheel width also affect compatibility; simply matching bolt pattern is not enough.
- Some vehicles use slightly different specs in special editions; always verify the exact spec for your vehicle.
In practice, when you see 6x139.7 vs 6x5.5, they're the same pattern, just labeled in different measurement systems. A wheel marketed as 6x139.7 will fit the same hub pattern as a wheel labeled 6x5.5 inches, provided the other specs align.
What this means for owners
For owners looking to replace wheels or upgrade, the rule of thumb is straightforward: match the lug count and bolt circle diameter; then verify center bore and offset. If you’re unsure, consult the vehicle’s specifications or a professional installer.
Summary
The bolt pattern 6x139.7 and 6x5.5 are the same pattern described in two measurement systems. They describe six lug holes spaced on a circle of 139.7 millimeters in diameter, which equals 5.5 inches. Always verify additional wheel specs to ensure a proper fit.
Is 6x139 7 bolt pattern the same as 6x5 5?
Yes, the 6x139.7 bolt pattern is the same as the 6x5.5 bolt pattern, as they are simply metric and standard measurements of the same pattern. The "6" indicates the number of lug nuts, while "139.7" mm is the metric equivalent of 5.5 inches for the bolt circle diameter.
- 6x139.7: This is the metric measurement.
- 6x5.5: This is the standard imperial measurement of the same bolt pattern.
- Compatibility: You can use a 6x5.5 wheel on a vehicle with a 6x139.7 bolt pattern, and vice-versa, as they are physically the same size. This is a very common bolt pattern for trucks and SUVs from brands like Chevrolet, GMC, and Toyota.

Is 6x135 and 6x139 7 the same?
The main difference is that 6x135 is a bolt pattern used by Ford trucks and SUVs, while 6x139.7 is used by many other manufacturers, including Chevrolet, GMC, and Toyota. They are not interchangeable, and wheels with a 6x135 bolt pattern will not fit on a hub with a 6x139.7 bolt pattern, and vice-versa. You can only use an adapter to convert between the two patterns.

Key differences
- 6x135: This bolt pattern is specifically used by Ford vehicles, including the F-150, Expedition, and Lincoln Mark LT/Navigator.
- 6x139.7: Also known as 6x5.5 inches, this is a common bolt pattern for many other brands, such as Chevrolet, GMC, and Toyota.
- Incompatibility: A wheel with a 6x135 bolt pattern cannot be directly mounted onto a 6x139.7 hub because the spacing between the lug holes is different.
- Solution: To use wheels from one pattern on a vehicle with the other, you must use a wheel adapter. These adapters are designed to convert one bolt pattern to another, allowing the wheels to be properly mounted.
Important considerations when using adapters
- Center bore: Adapters must match or be larger than your vehicle's hub bore, which can differ between brands even with similar bolt patterns (e.g., Ford vs. Chevrolet).
- Offset: Adapters can change your wheel's offset, which affects how far the wheel sits from the hub. This can be useful for achieving a desired look or clearing wider tires, but it's important to choose the correct thickness to avoid rubbing issues.
- Hardware: Ensure the adapter's studs and lug nuts are high-quality and have the correct thread pitch for your vehicle.
