What is Wheel Offset?
Wheel offset, also known as ET (Einpresstiefe in German), is one of the most critical factors when choosing new wheels for your vehicle. It measures the distance from the wheel's centerline to the mounting surface, expressed in millimeters.
Understanding offset ensures proper fitment, prevents suspension interference, and maintains optimal handling characteristics.
Types of Wheel Offset
1. Positive Offset (ET+)
The mounting surface is toward the front of the wheel (outside). This pushes the wheel inward toward the suspension. Most modern vehicles use positive offset.
2. Zero Offset
The mounting surface is exactly at the wheel's centerline.
3. Negative Offset (ET-)
The mounting surface is toward the back of the wheel (inside). This pushes the wheel outward, giving a more aggressive stance.
How to Find Your Correct Offset
- Check your current wheels - Look for ET marking on the wheel behind the tire or in your vehicle's door jamb sticker
- Consult your dealer - Elite BBS experts can provide offset recommendations for your specific vehicle
- Use online fitment guides - Many BBS dealers offer fitment calculators
Common Vehicle Offset Ranges
- BMW 3/4/5 Series: ET20 to ET35
- Mercedes-Benz C/E/CLA: ET35 to ET45
- Porsche 911: ET20 to ET30
- Audi A4/A5/A6: ET20 to ET35
What Happens with Wrong Offset?
Incorrect offset can cause:
- Rubbing against suspension components
- Accelerated tire wear
- Compromised handling
- Increased stress on wheel bearings
