Shinko Motorcycle Tires SR777 HD Cruiser Rear Tire 160/70-17 Black Wall — Heavy-Duty Stability & Wet/Dry Traction

The Shinko SR777 HD Black Wall 160/70-17 79H is a heavy-duty rear cruiser tire engineered to deliver confident wet- and dry-road traction, reinforced stability, and a comfortable ride for V-Twin and metric cruisers.

This rear bias street tire from Shinko Motorcycle Tires pairs a cruiser-optimized tread pattern with an H.D. reinforced carcass and aramid belt to balance load capacity, lateral stability, and rider comfort. Designed to fit many V-Twin and metric cruiser models, the SR777 HD is sized at 160/70-17 with a 79 load index and H speed rating, making it a common replacement for riders who want reliable handling without sacrificing ride quality.

How does the SR777 HD improve traction in wet and dry conditions?

The SR777 HD uses a rubber compound and an active tread design with functional siping and grooves that evacuate water and increase contact patch consistency. That combination helps maintain grip during acceleration, braking and cornering whether the pavement is damp or dry.

• Functional siping for extra biting edges on slick surfaces
• Groove channels to disperse standing water
• Compound tuned for balanced wet/dry performance

What makes the Heavy Duty (H.D.) construction different?

The H.D. version of the SR777 adds a reinforced carcass and an aramid belt that increases lateral stiffness and load capability. The result is a more planted feel under cornering and stability at highway speeds, especially when carrying passenger or luggage loads.

• Reinforced carcass for reduced flex and improved stability
• Aramid belting for higher load capacity and consistent handling
• Designed to resist deformation under heavier weights
