Is there a big difference between 18-inch tires and 19-inch tires in driving?

In addition to the rich configuration, most luxury cars and some household roofs have one thing in common: the big wheels. Many consumers also use large wheels as a synonym for luxury cars and good cars. The bigger the wheel, the more face it will be. The obvious difference in the low, medium and high configuration of some models is reflected in the size of the wheels. For example, Land Rover Aurora's new version, fashion version and Zhiyao version, although there are some differences in configuration, but the main selling point is still on the big wheels.

Take Land Rover Aurora as an example. With the increase of 18/19/20 inch wheels, the price is also increased by 50,000 (of course there are also more configurations). Many consumers will have difficulties. Is the difference obvious? Is there a big difference in actual use?

First inch refers to inches, 18/19/20 inches refers to the diameter of the wheel rim, 1 inch = 2.54 cm, the bigger the wheel, the most intuitive feeling is good-looking and atmospheric. Secondly, theoretically, the smaller the wheel hub of the same model, the thicker the tire (larger aspect ratio), and the driving comfort will be improved. In addition to the big wheels, most of the tires will have smaller flatness ratios, better handling, more sporty, high safety performance, and strong stability.

So in actual use, is there a big difference between 18-inch and 19-inch? Although the difference is not big, there are also certain differences. After all, every inch increase is a "qualitative change" after the 17-inch. Every inch of the wheel hub increases, the corresponding replacement tires will be flatter, with thin sidewalls, increasing the contact area of the wheel, and stronger grip, especially in cornering and wet control, reduced lateral shaking, and more stable and safe braking performance. Higher sex. But at the same time, when the tire wall becomes thinner, the shock absorption function is also reduced, and the comfort and quiet performance are reduced. If you encounter a bad road, the thin tire wall is easily damaged. In addition, an increase in the contact area will also cause an increase in friction and fuel consumption.

Compared with 19-inch wheels, 18-inch wheels are equipped with the same type of tires. Although they are slightly inferior in terms of handling performance, safety and stability, they will make up for them in terms of comfort, quietness, and fuel economy. The probability of damage is low.

The choice of the two wheels depends entirely on personal needs. Those who pursue driving pleasure should choose a large wheel, and those who enjoy driving comfort should choose a smaller wheel. They also need to consider the price, brand, and practicality.
