Shinko Motorcycle Tires SR777 180/65-16 Rear Cruiser Tire Black Wall — Stable Handling, Wet/Dry Traction

The Shinko 87-4599 SR777 (and H.D.) is a 180/65-16 rear cruiser tire engineered for stable handling, reliable traction, and increased load capacity for V‑Twin and metric cruisers.

This rear tire blends a rider-focused rubber compound, purposeful tread geometry and optional heavy‑duty reinforcement to deliver predictable grip and comfort across everyday street conditions. Offered in sizes that suit many cruiser platforms, the SR777 family aims to improve cornering confidence and stability while maintaining a compliant ride for long miles in variable weather.

How does the SR777 improve wet and dry traction?

The SR777’s tread pattern incorporates functional siping and grooves that evacuate water and increase bite on pavement, while the rubber compound balances adhesion and longevity. This combination helps the tire maintain contact patch consistency and reduces slippage risk when accelerating, braking or leaning through turns.

• Directional grooves channel water away from the footprint
• Siping increases edge grip on slick surfaces
• Compound tuned for both grip and even wear

What are the handling and comfort characteristics on long rides?

The SR777 is formulated to offer a comfortable ride without sacrificing stability; the carcass and belt construction manage road inputs while isolating harshness. Riders will notice steadier steering and a planted feel during sustained cruising, plus consistent feedback through corner transitions.

• Balanced carcass for reduced vibration and predictable steering
• Profile optimized for cruiser geometry and lean behavior
• Compound engineered to dampen small bumps for longer trips

When should you choose the H.D. (Heavy Duty) version?

Pick the H.D. variant if you need increased load capacity, heavier touring gear, or a more rigid feel at speed. The reinforced carcass and aramid belting give the tire greater resistance to deflection, improving stability under heavier loads and during aggressive maneuvers.

• Reinforced carcass for higher load capability (useful with luggage and passenger)
• Aramid belting adds structural stability and consistent footprint shape
• Recommended for riders who prioritize planted handling under load
