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 in relation to the vehicle's suspension components.

2. How Does the Calculator Work?

The calculator uses the wheel offset formula:

\[ \text{Vehicle Offset} = \text{Stock Offset} + \text{Modification} \]

Where:

Stock Offset — Original wheel offset from manufacturer (mm)
Modification — Any changes made to the wheel or suspension (mm)
Vehicle Offset — Resulting wheel position relative to stock

Explanation: Positive offset means the wheel mounts closer to the street side, negative offset means it mounts closer to the suspension side.

3. Importance of Correct Wheel Offset

Details: Proper wheel offset ensures correct wheel positioning, prevents rubbing against suspension components, maintains proper scrub radius, and affects vehicle handling characteristics.

4. Using the Calculator

Tips: Enter your vehicle's stock wheel offset and any modifications (spacers, different wheels, etc.) in millimeters. The calculator will show your resulting wheel offset.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical wheel offset range?
A: Most passenger vehicles have +25mm to +50mm offset. Performance cars may have lower positive offsets, while trucks often have higher positive offsets.

Q2: How does offset affect my vehicle?
A: Lower offset pushes wheels outward for wider stance, while higher offset tucks wheels inward. Extreme changes can affect handling and stress suspension components.

Q3: What's the difference between offset and backspacing?
A: Offset measures from centerline, while backspacing measures from the back of the wheel to the mounting surface.

Q4: Can I use wheel spacers to change offset?
A: Yes, spacers effectively reduce offset (1mm spacer = -1mm offset change), but must be used carefully to maintain proper lug nut engagement.

Q5: How much offset change is safe?
A: Generally ±5mm is safe for most vehicles, but consult your manufacturer's specifications or a wheel specialist for major changes.
