The Kumho Crugen HP91 is an ultra-high-performance (UHP) tire designed specifically for premium SUVs and light trucks. It features an asymmetric tread design and four wide circumferential grooves that offer enhanced stability at high speeds, precise cornering, and excellent wet traction. Engineered with a silica-rich compound, the HP91 is built to perform reliably on both dry and wet roads — making it a strong contender for hot climates like Saudi Arabia.
