DynGro Series
India's Largest Designer and Manufacturer of Standards-Compliant Tyre Testing Solutions
The DynGro Series consists of purpose-built systems designed to measure the maximum centrifugal expansion of a tire when rotated at its peak rated speed. These machines are engineered to comply with the stringent requirements of IS 15627 (Clause 4.3.1) for 2 and 3-wheelers, as well as UN/ECE Regulation No. 75, which governs the approval of pneumatic tires for motorcycles and mopeds.
Available in Standard and Heavy-Duty variants, the DynGro series utilizes high-precision laser sensors to capture real-time dimensional changes across 2-wheeler, 3-wheeler, and 4-wheeler tire categories. Every unit features a fully automated, PC-based control system with manual overrides and an integrated high-speed camera to provide frame-by-frame visual documentation of tire behavior under extreme rotational stress.

Capabilities
PC-controlled automatic test execution with no manual intervention required.
High-accuracy laser sensors measure diameter growth without touching the tyre surface.
Captures tyre behaviour at speed for visual inspection and analysis of growth.
Meets international regulation requirements for 2W / 3W tyre dynamic growth testing.
Supports both manual control panel operation and full PC-automated test sequences.
Suitable for standards from China, Vietnam, Kenya, France, Brazil, and the USA.
