The Infiniti Q50 is a luxury sedan known for its sleek design, smooth performance, and advanced features.
As a part of Infiniti’s lineup, it offers a balance of comfort and power, making it a popular choice for drivers who want both style and reliability.
With a focus on technology and driving experience, the Q50 stands out in the luxury sedan market.
When upgrading or replacing wheels, knowing the bolt pattern is essential. The bolt pattern determines which wheels will fit securely on the car.
Choosing the wrong bolt pattern can lead to issues with stability, alignment, and safety. If you are upgrading to custom wheels or replacing damaged ones, understanding the correct bolt pattern ensures a proper fit and smooth driving experience.
In this blog, we will explore the Infiniti Q50 bolt pattern, its compatibility, and tips for choosing the right wheels for your vehicle.
What is the Bolt Pattern for the Infiniti Q50?
The bolt pattern is an important measurement that determines which wheels fit properly on a car. For the Infiniti Q50, the standard bolt pattern is 5×114.3mm (also written as 5×4.5 inches).
This means the wheel has five lug holes, and they are arranged in a circle with a diameter of 114.3mm.
The Role of the Bolt Pattern
- Ensures a Secure Fit: The right bolt pattern ensures the wheel sits firmly on the hub, reducing the risk of loose wheels.
- Prevents Damage: Using an incorrect bolt pattern can lead to stress on the wheel studs and uneven tire wear.
- Improves Driving Stability: A properly fitted wheel provides better handling, alignment, and road grip.
- Allows for Customization: Knowing the bolt pattern helps when upgrading to custom wheels or aftermarket rims.
Before buying new wheels, always check that they match the 5×114.3mm bolt pattern to ensure proper fitment and a safe driving experience.
Understanding the Infiniti Q50 Bolt Pattern and Its Compatibility
The Infiniti Q50 bolt pattern is a key factor in selecting the right wheels for your car.
The standard bolt pattern for the Infiniti Q50 is 5×114.3mm (5×4.5 inches), meaning the wheel has five lug holes arranged in a circle with a diameter of 114.3mm.
Knowing this measurement ensures that replacement or aftermarket wheels fit securely.
Many Infiniti and Nissan models use the 5×114.3mm bolt pattern, making it easier to find compatible wheels. Here are some models that share the same pattern:
- Infiniti Models: Q60, G35, G37, FX35, FX45
- Nissan Models: Altima, Maxima, 350Z, 370Z, Murano
Although these vehicles have the same bolt pattern, factors like wheel offset and center bore can differ, so it’s important to check those measurements before swapping wheels.
Things to Consider When Choosing Aftermarket Wheels
- Wheel Offset: The distance between the mounting surface and the wheel’s centerline affects how the wheels sit on the car. Too much or too little offset can impact handling and tire clearance.
- Center Bore Size: The Infiniti Q50 has a center bore of 66.1mm. Hub-centric rings may be needed for a proper fit if the aftermarket wheel has a larger bore.
- Lug Nut Type: The Q50 uses M12x1.25mm lug nuts, so aftermarket wheels must be compatible with these specifications.
Matching the bolt pattern, offset, and bore size ensures the wheels fit correctly and provide a safe, smooth driving experience.
List of the Correct Bolt Pattern for Different Infiniti Q50 Models
The Infiniti Q50 bolt pattern has stayed consistent across most model years, making it easier for owners to find compatible wheels.
The standard bolt pattern is 5×114.3mm (5×4.5 inches), which means the wheel has five lug holes arranged in a 114.3mm circle.
This measurement ensures a proper fit and prevents misalignment, poor handling, or wheel vibrations.
Infiniti Q50 Bolt Pattern for Different Years

- Lug Nut Size: M12x1.25mm
- Factory Wheel Sizes: 17-inch, 18-inch
- Offset Range: +30mm to +50mm
The 2014 Infiniti Q50 was the first model year of this luxury sedan. It featured standard 17-inch or 18-inch wheels, depending on the trim level.
The bolt pattern has remained the same, making it easy to swap wheels with newer models as long as other factors like offset and bore size match.
2018 Infiniti Q50

In 2018, Infiniti updated the exterior styling and interior features, but the bolt pattern remained unchanged. However, this model year introduced 19-inch wheels on higher trims, which may have a slightly different offset than previous models.
Before swapping wheels between different trims or model years, always confirm that the offset, center bore, and wheel width are compatible.
2023 Infiniti Q50
- Bolt Pattern: 5×114.3mm
- Center Bore: 66.1mm
- Lug Nut Size: M12x1.25mm
- Factory Wheel Sizes: 18-inch, 19-inch, 20-inch (Red Sport 400 trim)

The latest Infiniti Q50 models, including 2023, still use the 5×114.3mm bolt pattern, meaning wheels from previous years will often fit.
The Red Sport 400 trim comes with 20-inch wheels, requiring careful offset when swapping with lower trims. Always verify wheel width, offset, and bore size despite the same bolt pattern for a perfect fit.
Are There Any Differences in the Bolt Pattern?
From 2014 to 2023, the Infiniti Q50 bolt pattern has remained the same, making it possible to use wheels from different years if other specifications match.
However, trim levels and factory wheel sizes may impact fitment due to offset, brake clearance, and tire width changes. Always check these details before installing new wheels to avoid clearance issues with the suspension or fenders.
How to Identify the Correct Bolt Pattern for a Specific Infiniti Q50?
Knowing how to measure the bolt pattern of your Infiniti Q50 can help when choosing new wheels. Even though the 5×114.3mm bolt pattern is standard, it is still good to understand how to measure it correctly.
Step-by-Step Guide to Measuring the Bolt Pattern
- Count the Lug Holes: The Infiniti Q50 has five lug holes, making it a 5-lug pattern.
- Measure the Bolt Circle Diameter: Since the Infiniti Q50 has an odd number of lugs, measure from the center of one lug to the farthest edge of the opposite lug. This gives you 114.3mm (or 4.5 inches).
- Check the Center Bore: The Infiniti Q50 has a 66.1mm center bore, which should match the new wheel for a proper fit.
- Verify the Lug Nut Size: The Infiniti Q50 uses M12x1.25mm lug nuts, meaning they have a 12mm diameter and 1.25mm thread pitch.
Tools Needed for Accurate Measurement
- Measuring tape or calipers – For precise bolt circle diameter and center bore measurements.
- Bolt pattern gauge – A tool designed to accurately measure the bolt pattern of wheels.
- Lug nut thread gauge – Helps verify the lug nut size before installing new wheels.
Tips to Avoid Incorrect Wheel Fitment
- Always check the offset and center bore size before installing aftermarket wheels.
- Use hub-centric rings to avoid vibrations if the center bore is over 66.1mm.
- Ensure the lug nuts match the thread pitch to prevent loose wheels or stripped threads.
- Test-fit the wheels before mounting tires to confirm proper clearance with brakes and suspension.
By following these steps, you can accurately measure the bolt pattern and ensure new wheels fit properly without issues.
