The scalable Valve core / Valve core design

The scalable Valve core
The scalable Valve core

When inflating the tires of the bicycles, people always don't know whether they are full or not. In that case, a new design of the tires becomes more necessary. This design mainly focuses on the valve core, which will be pushed out above the red line by the full pressure inside of the tires to remind people not to inflate them anymore. It is very convenient in life to determine if the bicycle tires need air or not through the observation of the red line.
