When sourcing from this manufacturer, prioritize TBR (Truck and Bus Radial) specifications. Key metrics include the Ply Rating (PR), typically 16PR or 18PR for heavy-duty use, and the Load Index/Speed Symbol. Ensure the tyres feature reinforced bead structures and low rolling resistance compounds to improve fuel efficiency. For specific road conditions, verify the tread depth (e.g., 15mm-22mm) and tread pattern design (rib, lug, or mixed) to ensure suitability for long-haul or off-road applications.
