What are the different 6 lug patterns?
Six-lug patterns are defined by the bolt circle diameter and the number of mounting studs. The most common six-lug sizes are around 139.7 mm (5.5 inches) and 135 mm (5.31 inches), with additional patterns used on select makes and generations. Always confirm your vehicle’s exact bolt pattern before buying wheels or adapters.
In this article, we break down what those patterns mean, which sizes are most commonly encountered, and how to verify the correct fit for your vehicle. We’ll also cover practical tips for measuring and verifying compatibility to avoid misfits or safety issues.
Common six-lug bolt patterns
The following patterns are among the most frequently encountered six-lug bolt circle diameters in today’s market. They are listed with their approximate sizes to help you identify likely fits, while noting that exact compatibility depends on year, model, and hub specifications.
- 6x139.7 mm (6 on 5.5 inches) — The most widely used six-lug pattern, found on many SUVs, trucks, and light-duty pickups. Aftermarket wheels are broadly available in this size, making it the default starting point for many buyers.
- 6x135 mm (6 on 5.31 inches) — Used by a subset of mid-size and full-size pickups and SUVs. Always verify hub bore, offset, and lug thread specifications when considering wheels in this pattern.
- 6x120 mm (6 on 4.75 inches) — Appears on a smaller number of models, primarily among select trucks and off-road-oriented builds. Availability of wheels in this size is more limited than the 5.5-inch pattern.
Practically speaking, the exact fit for your vehicle will depend on more than the bolt circle diameter. Hub bore size, wheel offset, center bore, lug nut size, and threading all factor into whether a wheel will mount securely and run true at speed.
How to confirm your vehicle’s bolt pattern
To ensure you purchase wheels that fit, follow a straightforward verification process that works whether you’re shopping new wheels, take-off wheels, or aftermarket options.
- Locate the manufacturer’s specifications for your vehicle’s wheel bolt pattern in the owner’s manual or on the manufacturer’s official site.
- If you have access to the current wheels, count the number of lug studs (six for a six-lug pattern) and measure the distance across the lug centers to determine the PCD (bolt circle diameter).
- Measure the hub bore (center hole) diameter to assess hub-centric vs lug-centric fit and to ensure proper alignment and vibration control.
- Confirm lug thread size and pitch (for example, common passenger-car sizes are around 12x1.5 or 14x1.5, but this varies by brand and year).
Taking precise measurements and cross-checking with the vehicle’s official specs helps avoid incorrect purchases and ensures a safer, smoother installation.
Additional fit considerations
Beyond bolt pattern, consider wheel offset, wheel width, and center bore compatibility. Some wheels require spacers or adapters to fit different hub patterns, and improper offset can affect handling, brake clearance, and ABS sensor operation. When in doubt, consult a professional or refer to the wheel manufacturer’s compatibility charts for your exact vehicle and model year.
Summary
Six-lug patterns are defined by the bolt circle diameter and the six mounting points. The most common patterns today are 6x139.7 mm (6x5.5"), with 6x135 mm (6x5.31") and 6x120 mm (6x4.75") appearing on a range of models. Always verify the exact bolt pattern, hub bore, offset, and lug specs for your vehicle before purchasing wheels or adapters to ensure a proper, safe fit.

What are the different 6 lug bolt patterns?
Common 6-lug bolt patterns are 6x5.5 inches (or $6 \times 139.7$mm), used by many Chevy, Ford, and Toyota trucks and SUVs, and 6x135mm, used by Ford vehicles. Other 6-lug patterns include 6x114.3mm (6×4.56 cross 4.56×4.5 inches), 6x120mm, and 6x127mm (6×56 cross 56×5 inches). To determine your vehicle's specific pattern, measure the distance between the centers of two opposing lug holes.
Common 6-lug bolt patterns
| Pattern (inches) | Pattern (mm) | Common vehicles |
|---|---|---|
| 6x5.5 | 6×139.76 cross 139.76×139.7 | Many Chevy, Ford, Toyota trucks and SUVs |
| 6x135 | 6×1356 cross 1356×135 | Ford trucks and SUVs |
| 6x4.5 | 6×114.36 cross 114.36×114.3 | Nissan, Toyota, and older Chevy models |
| 6x5 | 6×1276 cross 1276×127 | Older Cadillac and some Jeep models |
| 6x5.3 | 6×1356 cross 1356×135 | Some older GMC and Chevrolet trucks |

How to measure a 6-lug pattern
- Remove: the lug nuts from two bolts that are directly opposite each other.
- Measure: from the center of one exposed bolt to the center of the other bolt. You can use a tape measure, ruler, or a digital caliper for the most accuracy.
- Convert: the measurement to either inches or millimeters for the final bolt pattern.
How to read a bolt pattern
A 6-lug bolt pattern is read as 6×6 cross6× [diameter], where "6" is the number of lug holes and "[diameter]" is the diameter of the circle that the lug holes form.
- Example: A 6×5.56 cross 5.56×5.5 pattern has six lug holes arranged in a circle that is 5.55.55.5 inches in diameter.
- Example: A $6 \times 139.7$mm pattern is the same as 6×5.56 cross 5.56×5.5 inches, just measured in millimeters.
Do all 6 lug rims fit the same?
No, not all 6-lug rims fit the same, because while the 6-lug bolt pattern (the distance between the lugs) may be the same, other critical factors like the center bore diameter, offset, and brake caliper clearance can prevent wheels from fitting correctly. Even within the same brand, different models and years can have varying specifications.
Factors to consider for a proper fit
- Bolt Pattern: The number of lugs and the diameter of the circle they form are the most basic match. A common 6-lug pattern is 6-on-5.5 inches, but this is not universal across all vehicles, say Greg Hubler Chevrolet.
- Center Bore: This is the hole in the center of the wheel that fits over the vehicle's hub. It can differ between manufacturers and even models, and a mismatch can cause the wheel to be centered on the studs instead of the hub, putting stress on the studs.
- Offset: This measurement indicates how the wheel's mounting surface is positioned relative to the wheel's centerline. Incorrect offset can cause the wheel to rub against other parts of the vehicle or sit too far out.
- Brake Clearance: The wheel must have enough clearance for the brake calipers and rotors. Some wheels, even with the correct bolt pattern, may be too small or have a design that won't clear the brakes on certain vehicles.
- Other Specifications: Other factors like the size and type of lug nuts, and the need for spacers, can also affect the final fit.
Is 6x5 5 bolt pattern the same as 6x139?
Yes, 6x139.7 is the same as 6x5.5 because they are simply different ways of measuring the same bolt pattern—one in millimeters and the other in inches. The notation refers to a wheel with 6 lug holes that are 139.7mm or 5.5 inches apart from each other.
- 6x139.7: This is the metric measurement for the bolt pattern.
- 6x5.5: This is the standard (imperial) measurement for the same bolt pattern.
- Usage: This is a very common bolt pattern, especially for trucks and SUVs, so you can use either measurement when looking for wheels for vehicles that use this fitment.
