One of the most visible features of vehicles with high or low configuration is the wheel hub assembly
. Car owners are paying more for premium models. Is is necessarily better to be equipped with the wheel hub assembly of large size? It is not necessary.
Generally speaking, when a car is designed, in order to maintain the same passability, driving attitude, torque output of the wheel with the same displacement, although the wheel hub assembly size is different, but the vehicle tire outside diameter is the same. In other words, if the wheel hub assembly size increases, the corresponding tire wall size will decrease. For example, the new passat 18-inch wheels come with 235/45 tires, while the 16-inch wheels come with 215/60 tires. (PS: 45 and 60 represent the percentage of the thickness of the tire wall to the tread width of 235 and 215)
In fact, the advantage of high-fit models equipped with large-sized hub and small-sized sidewall tires is that it is more athletic, more precise - control, and of more direct direction feedback. The biggest disadvantage is the sacrifice of comfort. As in known, the combination of a small wheel hub assembly and a thick tire wall filters out bumps in the road better than the front combination.
Of course, this more accurate sense of control, is based on good road conditions. If the road is more complex, it is difficult for large wheel hub assembly to have advantage. For example, there may be large and small potholes in some asphalt pavement. If you're driving a car with the large wheel hub assembly and a small tire wall, you're more likely to suffer the situation of a flat tire and a broken hub when you drive at high speed. The lower version of the thick wall plus the small wheel hub assembly is more likely to survive. Therefore, as far as passability is concerned, high-allocation models with large-size wheels may not have an advantage.
