TMSI Tire Buffing / Grinding Systems are designed for tire R&D, testing and validation, regulatory testing, and retreading applications. The systems support automated grinding of the tread, shoulder, and sidewall areas, with configurable control of tire profile and wear level to meet different test requirements.
Through precise and repeatable grinding processes, TMSI systems enable efficient preparation of test tires with specified wear conditions and target profiles. Typical applications include RFV / RRO / CONY correction, retread buffing, and the preparation of worn tires for UN ECE R117 testing.
To accommodate different tire sizes and applications, TMSI offers three models — BF-PC400, BF-TB600, and BF-MAX — covering PCR, LT, and TBR tires.
BF-PC400
A dedicated grinding solution for PCR and LT tires, suitable for tire correction, retread buffing, and test tire preparation for passenger car and light truck applications.
BF-TB600
Designed for TBR tires, the BF-TB600 accommodates larger tire dimensions, higher tire weights, and higher inflation pressures required for truck and bus tire applications.
BF-MAX
An integrated grinding solution for PCR, LT, and TBR tires. With one system covering applications from passenger car tires to truck and bus tires, BF-MAX provides greater equipment utilization and flexibility for multi-category tire R&D and testing.
