Is 5x4 75 bolt pattern the same as 5x120?
Not exactly. 5x4.75" translates to a bolt circle of about 120.65 mm, while 5x120 is exactly 120 mm. They are not interchangeable without adapters or a wheel specifically designed for both, and there are other fit factors to consider.
Beyond the numbers, hub bore size, offset, and brake caliper clearance also influence whether a wheel will fit a given vehicle. This article explains the difference, why the two patterns look similar, and how to verify compatibility before buying wheels.
What the numbers mean
Here is a quick breakdown of how the two patterns are defined and what that means for fitment.
Pattern definitions
- PCD vs bolt circle: The numbers describe how many lug holes (5) and the diameter of the circle those holes lie on (4.75 inches or 120 mm).
- Unit conversion: 4.75 inches equals about 120.65 mm; 120 mm equals 4.724 inches. The two are very close but not identical.
- Interchangeability caveat: Generally, you cannot mount wheels with 5x4.75" on a car that requires 5x120, or vice versa, without an adapter or a wheel designed to accommodate both patterns.
- Center bore considerations: The wheel’s center bore must fit the hub or be properly spaced with a hub-centric ring; otherwise the wheel may not center properly, even if lug holes align.
- Pattern vs offset: Even if the bolt pattern lines up, differences in offset or brake caliper clearance can prevent proper seating or rubbing.
- Practical reality: Some sellers list both patterns or use the term 5x120 because of rounding; always confirm with the wheel manufacturer or dealer.
In short, treat 5x4.75" and 5x120 as distinct on the pattern specification and verify with manufacturers or a trusted wheel shop before attempting a fitment.
How to check compatibility
Use these steps to confirm whether a given wheel will fit your vehicle or if an adapter is required.
- Verify the vehicle’s bolt pattern: check the owner's manual, VIN, or a reputable parts catalog to confirm whether your vehicle is 5x120, 5x4.75, or another pattern.
- Measure wheel PCD if the pattern is not clearly labeled.
- Check the wheel center bore: ensure the bore diameter is equal to or larger than the hub bore; use hub rings if needed for proper centering.
- Assess offset and brake clearance: confirm that the wheel's offset and width will not cause caliper or rotor interference and that it maintains adequate fender clearance.
- Consider adapters only if approved: if using an adapter to match 5x4.75 to 5x120, ensure the adapter is rated for your vehicle and wheel, and factor impact on hub-centric alignment and lug nut engagement.
- Consult professionals and test fit: when in doubt, work with a wheel shop or the manufacturer to confirm fitment and safety before driving.
Following these steps reduces the risk of improper fit, vibration, or brake clearance issues.
Summary
The 5x4.75" pattern and 5x120 mm pattern are very close in numerical value but not the same on a strict, mountable level. Exact compatibility depends on precise PCD, center bore, offset, and clearance. Always verify with the wheel manufacturer and, if needed, use properly rated adapters or select wheels specifically labeled for your vehicle's bolt pattern.
What is the 5X120 bolt pattern equal to?
A 5x120 bolt pattern is the metric equivalent of a 5x4.72-inch bolt pattern. While very similar, it is slightly different from the 5x120.7mm (5x4.75-inch) pattern, which is common on some vehicles like older Corvettes and Camaros. The difference is small (only 0.7 mm0.7 mm0.7 mm), but can cause issues if not addressed with proper adapters or hub-centric rings.
Key takeaways
- 5x120 mm is the same as 5x4.72 inches. This is a common bolt pattern for many modern vehicles.
- It is not the same as 5x4.75 inches, though the two are often confused. The difference is about 0.7 mm0.7 mm0.7 mm (0.028 inches).
- For a perfect fit, always match the exact bolt pattern. Trying to fit a 5x4.75 wheel onto a 5x120 hub (or vice-versa) can cause pressure on the studs and lead to damage or safety issues.
- Use proper adapters if needed. If your vehicle has a 5x4.75 bolt pattern and you want to use 5x120 wheels, you can use a wheel adapter. These adapters can help ensure a proper fit and reduce the risk of damage to your vehicle.
- Always check compatibility before buying. Before purchasing wheels for your vehicle, check its specific bolt pattern and compare it to the wheel's specifications. You can also check the manufacturer's website or consult a professional if you are unsure.
What is equivalent to 5X4 75?
The notation "5x4.75" is the same as 5x4 3/4 inches and is the metric equivalent of 5x120.65mm. This refers to a five-lug bolt pattern, common on many American and European vehicles.
- Inch measurement: "5x4.75" or "5x4 3/4".
- Metric measurement: "5x120.65mm".
- Metric approximation: Sometimes, this is rounded to "5x120mm," but this is not an exact match and can cause issues.
What lug pattern is the same as 5X4 75?
A 5x4.75 inch bolt pattern is the same as 5x120.65 mm. It is a very common bolt pattern for many classic American muscle cars and modern Corvettes. While some newer GM vehicles use a 5x120 mm bolt pattern, the slight difference in millimeter measurement means a 5x120 wheel might not be a perfect fit for a 5x4.75 application and vice-versa.
- Metric equivalent: 5x4.75 inches is equal to approximately 5x120.65 mm.
- Common usage: This pattern was widely used by GM for a long period, found on models from the 1940s through the modern era.
- Confusion with 5x120mm: Be aware that many modern GM vehicles, and certain aftermarket wheels, use a 5x120mm pattern. While very close, this difference of 0.65mm can be significant and may cause issues.
- Wheel fitment: Always verify the exact bolt pattern of your vehicle before purchasing new wheels. You should also confirm the center bore size and offset, as these are also critical for proper fitment.
Will 5X4-75 fit 5X120 bolt pattern?
Not professionally recommended to run 5x120 wheels on a 5x4. 75 car without proper adapters. It can be done, but may apply force on the lug studs in a direction it wasn't intended. Just look into the safety risks before installing.
