Lug Nut Sizes for the 2017 Subaru Impreza
When it comes to maintaining your 2017 Subaru Impreza, understanding the specifications of lug nuts is essential. The lug nuts are the unsung heroes of your vehicle’s wheel assembly, ensuring that your wheels remain securely attached while you navigate various terrains. In this section, we will explore the specific lug nut sizes for different trims and engines of the 2017 Impreza, along with the corresponding torque specifications.
Understanding Lug Nut Size
The lug nut size for the 2017 Subaru Impreza is crucial for ensuring a proper fit and secure attachment of the wheels. Using the wrong size can lead to stripped threads or compromised safety. The standard lug nut size for the 2017 Impreza is:
- Thread Size: M12 x 1.25
- Lug Nut Type: Conical (tapered) seat
This specification applies across various trims and engine configurations, making it easier for owners and mechanics to ensure compatibility when replacing or servicing lug nuts.
Lug Nut Torque Specifications
Proper torque is vital for the safe operation of your vehicle. Over-tightening can damage components, while under-tightening can lead to wheel detachment. For the 2017 Subaru Impreza, the recommended torque specifications are as follows:
| Trim/Engine | Torque (ft/lbs) | Torque (Nm) |
|---|---|---|
| Base Model | 90 | 122 |
| Premium | 90 | 122 |
| Sport | 90 | 122 |
| Limited | 90 | 122 |
Why Torque Specifications Matter
Adhering to the specified torque values is crucial for several reasons:
- Safety: Properly torqued lug nuts help prevent wheel separation, which can lead to serious accidents.
- Performance: Correct torque ensures that the wheels maintain optimal contact with the road, enhancing handling and stability.
- Component Longevity: Following the recommended torque specifications can prevent premature wear on brake components and wheel bearings.
In summary, understanding the lug nut sizes and torque specifications for the 2017 Subaru Impreza is essential for any owner or mechanic. This knowledge not only enhances safety but also contributes to the overall performance and longevity of the vehicle. Proper maintenance of lug nuts is a small yet significant aspect of vehicle care that should not be overlooked.

Understanding the torque specifications for both front and rear wheels is essential for maintaining the safety and performance of your 2017 Subaru Impreza. Below is a detailed chart that outlines the recommended torque values for each trim level, ensuring that you have the right information at your fingertips.
| Trim Level | Front Wheel Torque (ft/lbs) | Front Wheel Torque (Nm) | Rear Wheel Torque (ft/lbs) | Rear Wheel Torque (Nm) |
|---|---|---|---|---|
| Base Model | 90 | 122 | 90 | 122 |
| Premium | 90 | 122 | 90 | 122 |
| Sport | 90 | 122 | 90 | 122 |
| Limited | 90 | 122 | 90 | 122 |
Practical Recommendations for Wheel Maintenance
Maintaining the integrity of your wheels is crucial for both safety and performance. Here are some actionable recommendations to ensure that your 2017 Subaru Impreza remains in top condition.
Importance of Using a Torque Wrench
Using a torque wrench is essential for achieving the correct torque specifications. Unlike impact tools, which can easily over-tighten or under-tighten lug nuts, a torque wrench allows for precise adjustments. This precision is vital for:
- Preventing Damage: Over-tightening can strip threads or warp brake rotors, leading to costly repairs.
- Ensuring Safety: Properly torqued lug nuts reduce the risk of wheel detachment while driving.
- Maintaining Performance: Correct torque ensures that wheels are securely fastened, enhancing handling and stability.
Avoiding Impact Tools
While impact tools can speed up the process of removing and tightening lug nuts, they are not recommended for final tightening. The use of impact tools can lead to inconsistent torque levels, which may compromise safety. Always finish the tightening process with a torque wrench to ensure accuracy.
Periodic Torque Checks
It’s advisable to check the torque of your lug nuts periodically, especially after tire rotations or wheel changes. A good rule of thumb is to check the torque after the first 50-100 miles of driving following a wheel installation. This practice helps to ensure that the lug nuts remain securely fastened.
Proper Tightening Sequences
When installing wheels, follow a proper tightening sequence to ensure even distribution of pressure. The recommended sequence is often a star pattern, which helps to prevent warping of the brake rotor and ensures that the wheel sits evenly against the hub. Here’s a simple tightening sequence to follow:
- Tighten the top lug nut.
- Tighten the bottom lug nut.
- Tighten the left lug nut.
- Tighten the right lug nut.
- Continue in a star pattern until all lug nuts are tightened.
Best Practices for Securing Wheels
To further enhance the longevity and safety of your wheels, consider the following best practices:
- Use Anti-Seize Lubricant: Applying a small amount of anti-seize lubricant to the threads of the lug nuts can help prevent corrosion and make future removals easier.
- Inspect Regularly: Regularly inspect your wheels and lug nuts for signs of wear, rust, or damage.
- Consult Your Manual: Always refer to your vehicle’s owner manual for specific recommendations regarding lug nut sizes and torque specifications.
- Seek Professional Assistance: If you are unsure about any aspect of wheel maintenance, don’t hesitate to consult a professional mechanic.
By following these practical recommendations, you can ensure that your 2017 Subaru Impreza remains safe, reliable, and performs at its best. Proper wheel maintenance is not just a chore; it’s an investment in your vehicle’s longevity and your safety on the road.
