Is there a relationship between the size of car tires and car fuel consumption

as we all know, the size of tires varies with different levels of models. Generally speaking, the tire width of mini cars is mm, with appropriate coating on the fiber surface. For small cars, it is between mm, for compact cars, it is about mm, and for other cars, the difference is 30mm

tires are ring-shaped elastic rubber products that are ground rolled and assembled on various vehicles or machinery. Usually installed on the metal rim, it can support the vehicle body, buffer the external impact, achieve contact with the road and ensure the driving performance of the vehicle. Tyres are often used in complex and harsh conditions. They bear various deformation, load, force and high and low temperature effects when driving, so they must have high bearing performance, traction performance and cushioning performance. At the same time, it also requires high wear resistance and flexion resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used in tire production, which shows the ability of tires to consume rubber

from the perspective of tires alone, the wider the tread, the greater the contact surface with the ground, and the greater the friction with the ground, the better the grip, the more stable and comfortable the car is, and the better the corresponding handling. At the same time, the consumption of the oil electro-hydraulic servo universal testing machine will increase correspondingly. The wider and larger the tire, the higher the price. The flat ratio is about small, and the price is also more expensive. Because the manufacturing process is complex, it usually brings better grip, but at the same time, fuel consumption and tire noise may also increase. The smaller the number of the aspect ratio of the tire (the flatter the tire), the better the handling of the vehicle, but the comfort may be reduced, and the probability of bulging when the tire hits a foreign object may be increased. On the contrary, tires with high flat ratio have strong cushioning capacity, but have a poor feeling of the road surface and weak lateral resistance when turning

relatively speaking, if small and compact cars want to have better acceleration and lower fuel consumption, the tires are bound to be narrower, while the performance and luxury cars are wider. When choosing to buy a car, on the premise of ensuring the basic braking performance, it is better for owners who pay attention to "fuel consumption" and "raising a new speed sense" to choose narrow tires

tires are comprehensive commodities, and various performances will restrict each other. If you want to pursue controllability, you can choose single guide tires, but such tires may have greater noise; If the most important thing is comfort, you can choose tires with scattered pattern blocks. Such tires have good shock absorption effect, but will sacrifice a certain degree of handling. In addition, safety is relative. Every car has its own tire size, which makes it difficult for enterprises to enter. If it is too narrow, it is unsafe, and if it is too wide, it will increase fuel consumption and damage the suspension system. The car is designed to match the appropriate tire, and it is best not to change it at will
