What is the bolt pattern on a Subaru rim?
The bolt pattern on a Subaru rim refers to the arrangement and number of lug bolts or studs that secure the wheel to the vehicle's hub. This pattern is an important consideration when replacing or upgrading wheels on a Subaru, as it ensures the new wheels will properly fit and function with the vehicle.
What is a Bolt Pattern?
A bolt pattern, also known as a lug pattern, is the specific configuration of lug bolts or studs on a vehicle's wheel hub. This pattern determines the number of bolts and their spacing, which must match the wheel in order for it to be properly mounted and secured.
Subaru Bolt Pattern Specifications
The standard bolt pattern for most Subaru models is 5x100mm. This means the wheel has 5 lug bolts or studs arranged in a circular pattern with a diameter of 100 millimeters. Some Subaru models, particularly higher-performance variants, may use a 5x114.3mm bolt pattern instead.
- 5x100mm: The most common Subaru bolt pattern, found on models like the Impreza, Outback, and Forester.
- 5x114.3mm: A slightly larger bolt pattern used on some higher-end Subaru models, such as the WRX and STI.
It's important to verify the correct bolt pattern for your specific Subaru model before purchasing replacement wheels or tires.
Why Bolt Pattern Matters
The bolt pattern is critical for the proper and safe installation of wheels on a Subaru. If the bolt pattern of the new wheel does not match the vehicle's hub, the wheel will not fit correctly and could become loose or detached while driving, posing a serious safety hazard.
Ensuring the correct bolt pattern is essential for maintaining the structural integrity of the wheel-to-hub connection and preventing potential accidents or damage to the vehicle.
