Are Bigger Car Wheels Always Better?

[Maureen]

Car wheels are not necessarily better when they are bigger. Larger wheels typically come with thinner tires and a smaller aspect ratio; conversely, smaller wheels have a larger aspect ratio. The aspect ratio plays a significant role in determining the comfort and smoothness of the ride. Here are some key points about car wheels: 1. The wheel hub is the cylindrical metal component inside the car tire that supports the tire and is centered around the axle. In simple terms, it is the part of the wheel where the axle is mounted, serving as a critical component that connects the brake drum (or brake disc), wheel disc, and axle. 2. In the market, wheel hubs can be categorized into steel wheels and alloy wheels based on material. The primary advantages of steel wheels are their simple manufacturing process, relatively low cost, and strong resistance to metal fatigue. Alloy wheels, on the other hand, are lighter in weight, have lower inertial resistance, higher manufacturing precision, and minimal deformation at high speeds, which helps improve the car's straight-line driving performance, reduces tire rolling resistance, and consequently lowers fuel consumption.
