Wheel Offset Calculator
The Wheel Offset Calculator is a tool used to determine the offset of your vehicle's wheels. The offset measures the distance between the wheel's hub mounting surface and the centerline of the wheel. This helps ensure that your wheels are correctly positioned to avoid clearance or handling issues.
The formula for calculating the wheel offset is: Offset = Backspace - (Wheel Width / 2).
To use the Wheel Offset Calculator, simply input the wheel width and backspace values, and the calculator will determine the wheel's offset. A positive offset pushes the wheel inward, while a negative offset pushes it outward. This can affect vehicle handling, tire clearance, and appearance.

FAQs
What is a wheel offset?
Wheel offset is the distance from the wheel's centerline to the mounting surface of the wheel, determining how far the wheel sits inside or outside the vehicle’s wheel well.
How do I know if my wheel offset is correct?
Your wheel offset is correct if the wheels clear the brake components and the suspension while not rubbing the wheel well or tire. It’s also important for aesthetic and handling reasons.
What happens if the wheel offset is too high?
If the wheel offset is too high, the wheels may be pushed inward, causing rubbing against suspension components, brakes, or the inner fender. This could affect vehicle handling and tire clearance.
What happens if the wheel offset is too low?
A low offset means the wheel is pushed outward, which may cause tire rubbing against the outer fender and negatively affect vehicle handling and stability.
Can I change the wheel offset of my vehicle?
Yes, but it’s essential to use the correct offset for your vehicle to avoid clearance issues and maintain proper handling. Custom wheel spacers or aftermarket wheels can alter the offset.
Is a positive or negative offset better?
Whether a positive or negative offset is better depends on the desired wheel positioning. A positive offset pushes the wheel inward, while a negative offset pushes it outward.
Does wheel offset affect steering?
Yes, the wheel offset can affect steering. A larger or smaller offset than what is recommended may cause uneven handling, steering issues, or alignment problems.
Can wheel offset affect suspension geometry?
Yes, incorrect wheel offset can affect suspension geometry, leading to handling issues, abnormal tire wear, and possible damage to suspension components over time.
What are some common wheel offset sizes?
Common offsets for most vehicles range from +35mm to +45mm, but it can vary depending on the vehicle make and model. It’s important to consult the manufacturer’s recommendations for your specific car.
How does wheel offset affect appearance?
Wheel offset can significantly affect the appearance of your vehicle. A larger negative offset can give a more aggressive, wider stance, while a positive offset tucks the wheels inward for a more subtle look.
