Automatic bead seating function (automatic over-inflation function), basic specification

Occasionally, when a new tire is installed onto a wheel, there are often cases that the tire bead does not attach well to the wheel. It is especially common in aluminum wheels and rusty steel wheels equipped with recently widely used wide tires. Air pockets between the wheels and beads can cause the tire to move sideways as the car travels at a high speed while the vehicle is galloping on left and right curves. However, the equilibrium and the load balance of the wheels change proportionally according to the installed position on the wheel. Inadequate installation of tire bead causes fluctuation of balance after driving. As a result of this, a customer whose car has a wide tire on an aluminum wheel may experience balance fluctuation in a short period of time. To prevent the problem, equipment for over-inflation, in which air pressure is injected more than specified air pressure and air is taken again with the specific pressure, is used while rotating the roller pressing the bead portion.

How to use CERTON tire automatic air injector (AIRMATE)

• Over-inflation amount is determined and stored in advance with the operation key.
  - For passenger car tires, you can select from 0 to 100% of the specified pressure.
  - For truck tires, select from 0 to 20% of the specified pressure.
• After saving the over-inflation amount, set a target value and press the start button, and then air pressure is automatically injected to Over-inflation value, taking the air out to reach the target value.
