Hey Subaru enthusiasts! If you're looking for the definitive guide to the 2019 Subaru Impreza wheel specs, you've landed in the right spot. This article dives deep into everything you need to know about the wheels on your 2019 Impreza. Whether you're thinking about upgrading, replacing, or just want to understand the stock setup, we've got you covered. Let's get started and roll into the details!

Understanding Wheel Specs

Before we jump into the specifics for the 2019 Impreza, let's break down what those wheel specs actually mean. Understanding these terms will help you make informed decisions when it comes to your wheels and tires. Here's a quick rundown:

• Diameter: The diameter is the overall size of the wheel, measured from one end to the other through the center. It’s usually measured in inches. For example, a 17-inch wheel has a diameter of 17 inches.
• Width: The width refers to the measurement of the wheel from one inner edge to the other, also measured in inches. This is where the tire sits on the wheel. The width is crucial because it determines the range of tire sizes that can be safely mounted on the wheel.
• Bolt Pattern (PCD): The bolt pattern, also known as Pitch Circle Diameter (PCD), indicates how many bolts are used to secure the wheel to the hub and the diameter of the circle they form. It’s typically expressed with two numbers, like 5x100, where "5" is the number of bolts and "100" is the diameter in millimeters.
• Offset (ET): The offset is the distance between the wheel's mounting surface and its center line. It’s measured in millimeters and can be positive, negative, or zero. Offset affects how the wheel sits in the wheel well and can impact handling and appearance. A positive offset means the mounting surface is toward the outside of the wheel, while a negative offset means it’s toward the inside.
• Center Bore: The center bore is the diameter of the hole in the center of the wheel that fits over the vehicle's hub. It ensures the wheel is properly centered on the hub. If the center bore of the wheel is smaller than the hub, the wheel won't fit. If it's larger, you might need hub-centric rings to ensure proper alignment and prevent vibrations.

Why are Wheel Specs Important?

Understanding wheel specs is crucial for several reasons. First and foremost, using the correct wheel specs ensures your safety. Incorrectly sized wheels can affect your car's handling, braking, and overall stability. Secondly, the right wheel specs guarantee a proper fit. Wheels that don't fit correctly can rub against the suspension components or fenders, causing damage and affecting your driving experience. Finally, knowing the wheel specs allows you to explore different aesthetic options while maintaining the performance and safety of your vehicle.

As you can see, the bolt pattern and center bore are consistent across all trims, which is super helpful if you’re thinking of swapping wheels between different Impreza models. The main differences lie in the diameter and width, which can affect the tire sizes you can use.

Detailed Look at Each Spec

• Diameter: The diameter of the wheel impacts the overall look and ride quality of your car. A larger diameter wheel typically means a shorter tire sidewall, which can improve handling but may also result in a harsher ride. Conversely, a smaller diameter wheel usually provides a more comfortable ride but might not handle as sharply.
• Width: The width of the wheel affects the tire's contact patch with the road. A wider wheel can accommodate a wider tire, which can improve grip and handling, especially in performance applications. However, going too wide can lead to rubbing issues or affect fuel efficiency.
• Bolt Pattern (PCD): The 5x100 bolt pattern is specific to certain vehicles, including the Subaru Impreza. It’s essential to match this exactly when choosing new wheels, as using the wrong bolt pattern can be dangerous and prevent the wheel from properly mounting to the hub.
• Offset (ET): The offset plays a significant role in how the wheel sits within the wheel well. A lower offset will push the wheel further out, giving the car a wider stance. A higher offset will tuck the wheel further in. It's crucial to choose an offset that doesn't cause the wheel to rub against the suspension or fender.
• Center Bore: The 56.1 mm center bore ensures the wheel is properly centered on the hub. If you're using aftermarket wheels with a larger center bore, you'll need hub-centric rings to fill the gap and prevent vibrations.

Plus Sizing and Upsizing

So, you’re thinking about changing the wheel size on your 2019 Subaru Impreza? Many owners consider "plus sizing" or "upsizing" to improve the look and performance of their cars. Here’s what that means:

• Plus Sizing: Plus sizing involves increasing the wheel diameter while decreasing the tire sidewall height to maintain the same overall tire diameter. For example, moving from a 16-inch wheel to a 17-inch wheel and selecting a tire with a lower profile. This can improve handling and give your car a sportier look.
• Upsizing: Upsizing generally refers to increasing the wheel and tire size together. This can provide a more aggressive look and potentially improve grip, but it’s essential to ensure the new setup doesn't cause rubbing or other fitment issues.

Considerations for Plus Sizing and Upsizing

• Tire Size: When plus sizing or upsizing, it's crucial to choose the correct tire size to maintain the overall tire diameter. This ensures your speedometer remains accurate and prevents issues with ABS and other vehicle systems. Use an online tire size calculator to find the right tire size.
• Clearance: Ensure the new wheels and tires have enough clearance in the wheel wells. Check for any potential rubbing issues by turning the steering wheel lock to lock and inspecting the clearance between the tires and fenders, suspension components, and brake lines.
• Offset: Pay close attention to the wheel offset. A different offset can dramatically change how the wheels sit in the wheel wells. If you're going with a wider wheel, you might need a lower offset to maintain proper clearance.
• Weight: Consider the weight of the new wheels and tires. Heavier wheels can negatively impact acceleration, braking, and fuel efficiency. Look for lightweight options to minimize these effects.
