The main loss in fuel consumption during the process is to overcome all kinds of resistance. According to professional tests, the car to 100 km / h speed uniform speed, the main will be subject to air resistance, the friction between the internal parts of the car and the rolling resistance of the tire, the three accounted for 60% of the total resistance, respectively % And 25%. So the tires are good or bad, will be directly related to the vehicle fuel consumption.
The relationship between tire and fuel consumption
How does the rolling resistance of the tires produce? When the vehicle is running, the load applied to the tire will cause the tire to deform. As the tire rubber is viscoelastic, so when the tire deformation, it will lose part of the energy and into heat. Energy loss, is the main reason for the rolling resistance, accounting for about 90% to 95% of all rolling resistance. So as long as the tire rolling resistance, you can achieve the purpose of reducing fuel consumption.
In general, manufacturers in the production of a model, will do a lot of experiments for the vehicle to match the different tires, to achieve fuel-efficient situation. However, the reasons for mass production, manufacturers are difficult to best performance or the most fuel-efficient tires in the production car, therefore, in order to achieve lower fuel consumption, the owner can choose some of the more advanced green tires. Data show that: green tires can reduce the rolling resistance of more than 20%, so you can reduce the energy consumption of more than 5%.
The benefits of green tires (with silicon-containing recipes):
1. Added the silicon recipe is the green tire to achieve fuel-efficient tips, it can make the tire rolling resistance reduced. Adding a silicon material between the tread rubber molecules can effectively reduce the friction between the glue molecules, thereby reducing energy consumption and reducing rolling resistance.
2. Green tires will be designed to be asymmetrical pattern, destroyed the "wave formation", you can achieve the purpose of noise reduction.
3. Added silicone formulations of green tires have better flexibility and flexibility, and treads can better grasp the ground.
Width and fuel consumption
The flattened tires that convert tires to large wheels are undoubtedly one of the shortcuts for retrofitting the appearance and handling of vehicles, but at the same time gaining cool shape and enhanced handling, they also lead to increased fuel consumption. The wider the tread, the greater the rolling resistance, according to engineering tests, 185 mm tires and 175 mm tires rolling resistance can be a difference of 10%. As a result, the higher the tire, the higher the fuel consumption.
Tire pressure and fuel consumption
1. Tire pressure is too high, easily lead to abnormal fetal wear.
2. Tire pressure is too low, easily lead to abnormal shoulder wear.
Low tire pressure led to increased resistance to running, fuel consumption increased. On the contrary, within the prescribed range of appropriate pressurization, is conducive to reducing fuel consumption. But not blindly pressurized, because the tire pressure is too high will lead to abnormal wear of the crown, the final replacement of the entire tire, more harm than good.
Four - wheel positioning and dynamic balance and fuel consumption
Four wheel positioning is not accurate, there is no good balance, will lead to abnormal tire wear and tear to increase vehicle fuel consumption. Wheel positioning each deviation of 1 degree, then the vehicle every 1 km, the tires will slip 7 meters. When the vehicle is offset, the driver will adjust the direction of the instincts to keep the vehicle straight, which will cause the tire to produce additional force and deformation, consume more fuel.
1. Select the size, specifications in line with vehicle design tires. Try not to modify, if conditions can choose green tires.
2. Regular inspection tire tire pressure, professionals recommend the owner at least once a month check.
3. Keep the wheel positioning correct and dynamic balance to ensure normal fuel consumption.
