How to Explain Wheel Offset?

[AmaraRose]

Wheel offset refers to the distance from the mounting surface (the surface that contacts the hub) to the centerline of the wheel, which can be positive or negative. The impact of wheel offset on safety: Incorrect wheel offset can lead to uneven tire wear, rubbing against the fender, interference with steering, and serious safety issues. Zero offset means the two surfaces coincide, positive offset means the mounting surface is towards the outside, and negative offset means the mounting surface is towards the inside (closer to the braking system). In other words, the greater the positive offset, the more the wheel is tucked in; the greater the negative offset, the more the wheel protrudes outward from the vehicle body. Wheels can be divided into two main categories based on material: steel wheels and alloy wheels. Steel wheels: Advantages include simple manufacturing process, relatively low cost, and strong resistance to metal fatigue. Disadvantages include heavy weight, high inertial resistance, and poor heat dissipation. Alloy wheels: Advantages include lightweight, high manufacturing precision, high strength, low inertial resistance, excellent heat dissipation, and good visual appeal. Disadvantages include complex manufacturing process and high cost.
