TEMPERATURE emperature Digimaster 3 heat resistance (high-speed durability of the tire), the parameters in accordance with the provisions of the mapping method and steps in the test chamber tire test drum "non-stop" time to "do anything" to represent.

One rotation of the tire on the ground, which every angle to withstand the vibration force is not equal, this phenomenon is known as RFV (Radial Force Variation), when the ADS-1S RFV value is too large, the tire will generate vibrations affect driving comfort sex. The yellow hollow point is called the the tire light point mark, said this position is the site of the lightest on the circumference of the tire when the tire is replaced, the valve must be the most important position on this site with tire rims alignment with the installation, in order to make the wheels in traveling to maintain the best balance.
