The differences between a vacuum tire and a tire with an inner tube are: different valves, different signs and different wheels.
1. The valve is different
Observe the position of the tire valve to see if there is a rubber snap ring directly stuck on the wheel hub, and if there is one, it is a vacuum tire.
2. Different signs
The most obvious sign that distinguishes a vacuum tire from an ordinary inner tube is that there is a string of English letters TUBEL ESS on the tire side of the vacuum tire.
3. Different wheels
In order to prevent air leakage, the vacuum tire is a whole. Like our bicycle tires, the wheels are one by one. Such a tire is an ordinary inner tube. Because vacuum tires don't use banner wheels.
