Pity. Because the spare tire compartment is generally located at the rear of the vehicle, it is far away from the vehicle. In addition, the spare tire box itself is relatively hard, which is easy to produce * * * vibration effect and will amplify the noise. If you are sensitive to vehicle noise, I suggest you consider taking other measures, such as replacing noise-reducing tires, installing sound insulation felt, etc., to improve the sound insulation effect in the car.
