What size are Subaru wheel stud threads?
When it comes to maintaining or repairing your Subaru, understanding the specifications of its components is crucial. One common question among Subaru owners is about the size of the wheel stud threads. Whether you're replacing a damaged stud or upgrading your wheels, knowing the correct thread size ensures a proper fit and safe driving.
Understanding Subaru Wheel Stud Thread Sizes
Subaru vehicles typically use wheel studs with a specific thread size that varies depending on the model and year. However, the most common thread size for Subaru wheel studs is 12mm x 1.25. This means the stud has a diameter of 12 millimeters and a thread pitch of 1.25 millimeters. This size is standard across many Subaru models, including the Impreza, WRX, Forester, and Outback.
Why Knowing the Thread Size Matters
Using the correct thread size is essential for several reasons:
- Safety: Incorrect thread sizes can lead to improper torque, which may cause the wheel to loosen while driving.
- Compatibility: Ensures that aftermarket wheels or lug nuts fit securely without damaging the studs.
- Ease of Maintenance: Knowing the correct size simplifies repairs and replacements, saving time and effort.
How to Confirm Your Subaru's Wheel Stud Thread Size
While 12mm x 1.25 is the most common size, it's always a good idea to double-check your specific Subaru model. Here's how you can confirm the thread size:
- Consult your vehicle's owner's manual for detailed specifications.
- Contact your local Subaru dealership or a trusted auto repair shop like Kevin's Autos for expert advice.
- Use a thread pitch gauge to measure the thread size directly from the stud.
