Understanding Wheel Fitment
Wheel fitment refers to how a wheel fits onto your vehicle in terms of physical dimensions and alignment. Key specifications to know include:
- Bolt Pattern: This is the number of lug holes and the diameter circle they form. For example, 5×120 means five lugs in a 120 mm circle.
- Rim Size: Includes diameter and width, which determine the type of tires you can mount.
- Offset (ET): Measures the distance from the hub mounting surface to the wheel’s centerline. A higher offset pushes the wheel inward.
- Hub Bore: The center hole of the wheel that fits over the hub on your vehicle. It should match the car’s hub bore for a snug fit.
- Tire Size: Impacts ride comfort, handling, and overall appearance.
Understanding these terms ensures you make informed decisions, avoid compatibility issues, and maintain the safety and performance of your Acura MDX.
