1. What is Wheel Offset?

Wheel offset is the distance between the wheel's mounting surface and its centerline, measured in millimeters. It determines how far in or out the wheel sits relative to the vehicle's suspension components.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Offset1 \) — First wheel offset measurement (mm)
• \( Offset2 \) — Second wheel offset measurement (mm)

Explanation: A positive result means Offset1 sits further out than Offset2, while a negative result means it sits further in.

3. Importance of Offset Comparison

Details: Comparing wheel offsets helps when changing wheels, ensuring proper fitment without rubbing against suspension components or fenders.

4. Using the Calculator

Tips: Enter both offset values in millimeters. The calculator will show how much further in or out one wheel will sit compared to the other.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical wheel offset range?
A: Most passenger vehicles have offsets between +35mm to +45mm, but this varies by vehicle.

Q2: How does offset affect vehicle handling?
A: Lower offsets push wheels outward, potentially improving stability but increasing stress on bearings.

Q3: Can I use wheels with different offsets?
A: Generally not recommended as it can affect handling and wear components unevenly.

Q4: What's the difference between offset and backspacing?
A: Backspacing measures from the mounting surface to the inner edge, while offset measures from the centerline.

Q5: How much offset difference is acceptable?
A: Small differences (5-10mm) can often be accommodated, but consult a fitment specialist for major changes.
