Wheel offset refers to the distance between the centerline of a wheel and its mounting surface. This measurement is important because it determines how far inward or outward the wheel will sit in relation to the vehicle's hub.
The offset of a wheel can be positive, negative, or zero. A positive offset means that the mounting surface of the wheel is toward the outside of the wheel, while a negative offset means that the mounting surface is toward the inside of the wheel. A zero offset means that the mounting surface is at the centerline of the wheel.
The offset of a wheel affects the handling and appearance of the vehicle. A wheel with a positive offset will generally have a narrower track (the distance between the left and right wheels) and will sit more inward in the wheel well. This can improve the stability of the vehicle and make it easier to steer. However, it may also reduce the overall stance and give the car a more tucked-in look.
On the other hand, a wheel with a negative offset will have a wider track and will sit more outward in the wheel well. This can provide better stability during cornering and make the car appear more aggressive. However, it may also increase the risk of rubbing against the fender or suspension components.
It's important to choose a wheel with the appropriate offset for your vehicle to ensure proper fitment and performance. Many aftermarket wheel manufacturers offer wheels with different offsets to suit a wide range of vehicles and applications.
