Benefits: 1, improved grip and driving stability: 225 The wider the tire, the larger the contact area with the ground, which will increase the vehicle's grip and improve driving stability. 2. Enhanced handling: The diameter of 225 tire is higher, which can better maintain the stability of the vehicle and reduce the rollover risk when turning sharply. Disadvantages: 1, increasing fuel consumption and noise: 225 The wider the tire, the more sliding friction will be increased, which will make the steering wheel of the car turn more, mainly in the increase of fuel consumption and the wind noise is much louder than before. 2. It may affect the annual inspection of vehicles: increasing the tire width will interfere with the geometric specifications formulated by the body and suspension, which may lead to the failure of the annual inspection. 3. It may affect the balance of the car: increasing the tire width will change the center of gravity of the car and may affect the balance and driving experience of the car. 4. It may be reported that 2 15 and 225 both indicate the section width of the tire. Changing 2 15 to 225 is equivalent to changing the specifications of the tires, which may be reported to the vehicle management office.
