Dunlop Sportmax Q5S Rear Tire - 180/55ZR17 M/C (73W) TL, Part Number DUN45258206

The fifth generation Dunlop Sportmax Q5S sets the new benchmark for the ultimate street and track-day tire. Following in the development footsteps of the Q5, the Q5S has achieved even higher performance by utilizing aspects from Dunlop's cutting-edge road race tires developed in Buffalo, NY and used in the MotoAmerica Road Race Series. With an enhanced construction, profile, compound and tread pattern, the Q5S provides lighter,nimbler handling, with improved dry and wet grip to make it even more user-friendly, all while maintaining class-leading durability.

• MT Multi-tread technology uses silica-infused, long-wearing compound in the center of the tread for increased life, with special lateral grip compounds on the shoulders for maximum grip
• Intuitive Response Profile (IRP) allows for taller tire profile along with tapered sides for a more aggressive turn-tin response and feel
• Front tire profile and construction allows for a 7mm shorter tire, resulting in lighter steering feel and quicker turn-in rate
• Improved polymer compound and softer shoulder performs in both wet and dry conditions
• Optimized tread pattern aids in quick warm-up times and improved wear
• D.O.T.-approved

The Dunlop Sportmax Q5S rear tire is designed for riders who demand confident street performance and capable track-day handling. Developed using technology derived from Dunlop road racing tires used in the MotoAmerica Road Race Series, the Q5S combines responsive handling, strong dry grip, dependable wet-weather performance, and long-wearing durability. Its radial construction, tubeless design, and directional tread make it a focused choice for sport and sport-touring motorcycles equipped with a 17-inch rear wheel.

Dunlop’s MT Multi-Tread technology places a silica-infused, long-wearing compound in the center of the tread while using specialized lateral-grip compounds on the shoulders. This arrangement supports extended service life during everyday riding while maintaining traction during aggressive cornering. The Intuitive Response Profile uses a taller profile and tapered sides to promote quicker turn-in, lighter steering, and a more connected feel through transitions.

The Q5S also features an updated polymer compound and softer shoulder area to improve grip in both wet and dry conditions. Its optimized tread pattern supports rapid warm-up and consistent wear, helping the tire deliver predictable performance across street rides and spirited sessions. The front and rear tire profiles are engineered as part of the Q5S performance package, with this rear tire sized for 180/55ZR17 applications. The Dunlop Sportmax Q5S rear tire is D.O.T.-approved and identified by part number DUN45258206.
