Built with a strong 4-rib tread pattern, the RR99 handles the demands of diverse surfaces—from city roads to rough site access—while maintaining grip and control. The large open grooves and siped tread blocks help channel water efficiently and offer added traction in wet or uneven conditions.
A cut, chip, and tear-resistant rubber compound enhances durability in abrasive environments. The heavy-duty casing is reinforced with four full steel cap plies, adding strength against impact and improving puncture resistance.
Its tread design balances performance by reducing road noise for smoother highway driving while offering the toughness needed for off-road resilience. With a casing built for retreading, the RR99 is a practical and versatile solution for mixed-use fleets.
