Bead Area Durability in High-Load OTR Segments

1. The Industrial Challenge

Off-The-Road (OTR) tyres operating in mining and construction environments face extreme stress at the bead-rim interface. This bulletin addresses the re-engineering of the bead filler (apex) compound to increase hardness and thermal stability. By implementing a high-modulus compound with specialized resins, we prevent bead de-seating and rim chafin...
