New technology to improve RFV and RFV1H without appearance damage by traditional buffing method.  

By rectifying process, heating, stretching and pressurizing the bead areas, the concentricity of two beads improved and  stress concentration relieved, thus having the beads re-aligned with lower RFV AND RFV1H values.

Commonly, the first two major causes for RFV/ RFV1H: Asymmetrical beads and Stress concentration (See below flow chart). Repeated tests prove that the rectifying testing process has little influence on the tire in terms of LFV, LFV1H, CONY, and dynamic balance.

Additionally, the results of debead testing, strength, water pressure blasting, endurance, low pressure and high-speed tests before and after rectifying are more or less the same. RFV and RFV1H values obtained after rectifying do not rebound and remain constant.

Also, no damage to the beads or other parts after rectifying.
