Why do more expensive cars have wider tires? What is the impact of tire width on vehicles?

 Generally speaking, vehicles below 100000 yuan use narrow and small tires, with tire widths of 175mm, 185mm, and 195mm. The majority of tires have diameters of 14 inches and 15 inches. The more advanced cars and cars with larger displacement use wide and large tires, such as tires with widths of 225mm, 235mm, and 245mm. There is also a difference in tire width between high-end and low-end models of most cars, with low-end tires being narrower and smaller. The width of tires used in a car is definitely limited by cost, and inexpensive cars will not use too wide tires because wide tires have high costs. Besides, what are the differences between wide tires and narrow tires? Do you care about what tires are when buying a car?

From a visual perspective, wide tires are more visually impactful and appear more domineering. Whether viewed from the front or back, wide tires are more eye-catching, and the entire car will also appear more upscale with the support of wide tires. In terms of practical function and use, wide tires have higher ultimate performance. Due to the wide width of the tires and the large contact area with the ground, the grip is greater. When the vehicle accelerates rapidly, it has greater grip and will not easily slip. When braking, it can also generate greater friction, making the car stop faster. Driving stability will also be better, especially when turning, the tire limit is high, and even if the speed is relatively fast, it is not easy to exceed its limit. In case of understeer or oversteer, the whole car feels more stable when driving.

       Narrow tires also have advantages, such as low driving noise, light rotation, and good fuel economy. These advantages happen to be the drawbacks of wide tires, with relatively high noise and high fuel consumption. Narrow tires are all used on small cars. If the displacement is small and the car is also small, using large tires will greatly affect power and fuel consumption. It's like wearing a pair of heavy shoes to run, and people with little strength can't run fast at all. Most people who buy small cars are also concerned about fuel consumption, coupled with the cost of making cars, so they can only use narrow tires.

As a family car, even narrow tires are sufficient. After all, you don't often drive fiercely and drive the car to the limit, so there's no need to change narrow tires to wide tires. When buying a new car, you don't need to choose a high-end or a certain model for wide tires. Another thing that cannot be ignored is the cost of replacing tires. The price of wide tires is generally higher, with tires above 215mm ranging from over a thousand to over two thousand. The wider the tire, the higher the price, and replacing four tires also requires a lot of money. The 185mm and 195mm tires only cost a few hundred yuan, resulting in lower vehicle costs. Regardless of whether the tire is wide or narrow, the service life and mileage used are basically the same, and it is not that the wider the tire, the higher the price, the longer the usage time. Narrow tires are better in terms of economy and vehicle cost.
