What Is Wheel Offset?
ET Explained, Examples & Fitment Guide

What is offset?
It is the distance from the wheel’s centre line to the vehicle’s hub. A more negative offset pushes the wheels away from the chassis, giving the wheel a deeper dish. Conversely, a more positive offset sets the wheels further into the wheel arches, resulting in a wheel with less dish.
Getting the correct offset is essential for maintaining proper handling, steering, and clearance. The wrong offset can cause issues with suspension, wheel-arch clearance, and overall driving performance.
Whether you’re upgrading your 4×4 or improving off-road capability, understanding offset will help you choose the right fitment with confidence.
What Does ET Mean on Wheels?
You’ll often see wheel offset written as ET followed by a number, such as ET35.
ET stands for Einpresstiefe (German for “insertion depth”)
The number indicates the offset in millimetres
Example:
- ET35 = wheel sits 35 mm inward from the centreline (positive offset)
- ET-20 = wheel sits outward (negative offset)
Understanding ET markings helps you quickly compare wheels and ensure correct fitment.
How Do You Measure Wheel Offset?
Wheel offset is measured from the wheel’s centreline to the mounting surface
- A zero offset means the hub sits exactly in the middle
- A positive offset pushes the wheel inward
- A negative offset pushes the wheel outward
Example:
A wheel with ET-50 sits significantly farther out than a standard wheel, creating a wider stance.
How to Choose the Right Wheel Offset
Choosing the correct offset depends on how you use your vehicle:
- Daily driving → stick close to the factory offset
- Off-road driving → a slightly negative offset improves stance and clearance
- Performance/handling → A balanced offset improves stability
Always check:
- Suspension clearance
- Brake caliper space
- Wheel arch fitment
If unsure, it’s best to choose wheels designed specifically for your vehicle.
Choosing Wheels for Your 4×4
If you’re upgrading your wheels, offset is only one factor. You’ll also need to consider tyre type and intended use.
For example:
All-terrain tyres offer balanced on- and off-road performance
Mud-terrain tyres provide maximum grip in challenging conditions
Choosing the right combination of wheels and tyres ensures the best performance on and off the road.
Looking for a deeper dish look for your 4×4?
For vehicles such as Land Rover, Volkswagen, and Ford vehicles, selecting wheels with a deeper dish can enhance both appearance and performance, improving handling and grip.
If you’re upgrading your setup, it’s important to choose the right combination of wheels and tyres for your vehicle. Explore our range of all-terrain tyres for balanced performance, or mud-terrain tyres for more aggressive off-road use. You can also shop for alloy and steel wheels for your 4×4 to find the right fitment for your setup.
It’s always advisable to seek expert advice to ensure compatibility with your vehicle and avoid clearance or suspension issues. Our team is here to help.
Wheel Offset Explained (With Simple Examples)
Wheel offset is measured from the wheel’s centreline to the mounting surface, and it determines how your wheels sit within the wheel arches.
Negative Offset (ET-)
A negative offset means the mounting surface sits closer to the inside of the wheel, pushing the wheel outward.
Results:
- Wider stance
More aggressive look
Increased clearance in the inner suspension
Example:
A wheel with ET-20 will sit further out than a standard wheel, creating a deeper dish appearance.
Zero Offset (ET0)
A zero offset means the mounting surface aligns exactly with the wheel’s centreline.
Result:
Balanced positioning
Even spacing between the suspension and the wheel arch
Example:
A wheel with ET0 sits centrally within the wheel arch, maintaining a neutral stance.
Positive Offset (ET+)
A positive offset means the mounting surface is closer to the wheel’s outer edge, pulling the wheel inward.
Result:
Wheels sit further inside the arches
Improved stability and factory-style fitment
Example:
A wheel with ET35 sits further inward, which is typical of many factory wheel setups.
Quick Comparison
- Negative offset → pushes the wheels outwards
- Zero offset → centres the wheel
- Positive offset → pulls the wheels inwards
Why This Matters
Choosing the right offset affects:
- Handling and stability
- Suspension clearance
- Overall vehicle stance
Visual Guide
Our website features a helpful visual icon next to each wheel that indicates its offset value, allowing you to quickly determine whether a wheel has a positive, zero, or negative offset. Understanding offset is crucial for properly aligning your vehicle’s wheels. A positive offset extends the wheel outward, while a negative offset pulls it inward, and a zero offset positions the wheel directly in line with the hub. This visual guide streamlines your decision-making process and helps you choose the ideal wheel for your specific fitment needs.
