how does tire size affect speedometer
Now that the car has entered the homes of ordinary people, the car has become a means of transportation for many people now. The speed of the means of transportation is a problem that everyone has been concerned about. Next, let's introduce the impact of tire size on the speed of the car.The effect of tires on vehicle speed---the size of tires. The tire size has a complex relationship with the driving speed. In principle, the ratio of the original tires to the vehicle is the most reasonable, because the tire size is related to the dynamic performance of the vehicle. If the tire is too small, it will limit the power output and affect the speed.
The impact of larger tire size on the car is:
1. The resistance torque of driving under the same working conditions will change, that is, the acceleration and climbing force of the car will decrease, but theoretically the top speed of the car will increase;
2. The stroke of the wheel jumping up and down becomes smaller, and the suspension system (shock absorber) needs to be strengthened;
3. The actual vehicle speed is slightly higher than the displayed vehicle speed.
Note:
The speed displayed by the speedometer is calculated from the wheel axle speed and the diameter of the original tire. If the tire size is increased, and the speedometer shows 80KM, the actual speed should be 80 times the actual diameter/original tire diameter.
The influence of tires on the speed of the car---the width of the tires
The wider the tire, the larger the contact area to the ground, the larger the contact area, the greater the friction force, and the greater the friction force, the greater the power required to achieve the required speed than the narrow tire. The wider the tire, the smaller the contact area to the ground. The larger the contact area, the smaller the frictional force. The greater the frictional force, the smaller the power required to achieve the required speed than that of the narrow tire. The above are the tires introduced by the electric state editor for you. Will the tires affect the speed of the car? The introduction of the influence of tire size on the speed of the car hopes to be helpful to everyone. If you want to know more about the car, please pay attention to the electric state.
