Yes, studded tires are legal in Chile under strict conditions. The Reglamento de Tránsito (Decreto Supremo 170/2008) permits their use only in high-altitude regions during winter months, with mandatory municipal authorization. The Ministerio de Transportes y Telecomunicaciones enforces compliance, while the Superintendencia de Electricidad y Combustibles monitors tire quality standards. Recent 2026 amendments require studded tires to meet EU ECE R30 or UNECE R117 certification, aligning with Andean Community technical norms.
