What Is Wheel Offset Explained

Wheel offset is the distance from the hub mounting surface to the wheel centerline. The offset can be one of three types (measured in millimeters). Zero offsets are when the hub mounting surface is even with the centerline of the wheel.

What is wheel offset and how is it measured?

Wheel Offset is Measured In

In simple terms, wheel offset is the distance from the center of the wheel to its mounting surface. Wheel offset is measured in millimeters and results in a positive, negative, or no offset. It is standard practice to measure wheel offset in millimeters. The most common wheel offset measurement increments are +0mm, +15mm, +20mm, +25mm, +30mm and +35mm offsets.

What does offset mean on a car?

The offset is the direction and distance from the wheel mounting surface to the true centerline of the wheel. In other words, it is the distance between a line drawn through the center of the wheel and a line drawn through the mounting surface of that wheel where it meets your hub.

What is a zero offset rear wheel?

Zero Offset Wheels

Zero offset wheels mean that the mounting face of the wheel is even with the centerline of the wheels, where a positive offset means that the mounting face of the wheel is towards the outside of the wheel, and a negative offset means that this face is towards the inside. TSW Wheels have a positive offset.

What is the offset of a TSW wheel?

offset of a tsw wheel quality

Many wheels are available for use on passenger vehicles, but few of them can deliver the same reliability and visual appeal as a TSW wheel. Each one of our wheels is created using advanced production techniques and quality materials.

That combination allows us to deliver some of the best wheels on the market, including wheels available with different offsets.

What does +20 offset mean?

+20 Offset wheel

The +20mm option is the equivalent of a square (+0 offset) rim and tire. This offset provides more clearance between the strut and the wheel’s inner barrel and has a more aggressive look; as compared to a standard OEM setup.

What does +35 offset mean?

+35 Offset Wheel

Applies to wheels in the given size. The wheel is at its stock width and the offset is changed by design. When a wheel is made with +35mm offset the wheel does not just stick out 35mm from the stock wheel. When you increase the offset you move the wheel to be more flush with the fender well. Increasing a wheel’s offset moves where it sits inward toward the car.

What is wheel offset 40?

Wheel Offset 40

Wheels with a 40 offset need 40mm of the inner wheel housing to be safely cleared by the wheel. This may sound odd but this is why you will see wheels with an offset of +30 or -20 for example. Wheels that have a positive offset have the mounting circle positioned towards the front or wheel side of the wheel, tire in-between wheel, and hub face.

Whereas wheels with a negative offset have the mounting circle positioned towards the back or brake side of the wheel, tire in-between wheel, and spokes.

What does 15mm offset mean?

15mm Offset Wheel

15mm offset is a bolt-on assembly that slides onto all factory forks, clamps, and spindles found on most American-made ATVs. This hub is designed to move the tire out 1.5″ per side on a conventional 4/137 lug pattern, or for fitment of a wider and taller tire.

There comes a point where you need to fit a wider and taller tire than the stock setup can provide. A common misconception is that wider tire rim widths can be used to reach this goal, but in reality, they only end up being heavier and further away from the center of rotation.

Wheel offset is the measurement of where the wheel mounting surface is located, in relation to the centerline of the wheel. The easiest way to visualize wheel offset is to imagine a straight line that runs down the center of the wheel, from front to back. This centerline is where 0mm offset occurs. Thanks for reading.
