Shinko Motorcycle Tires SR777 HD Rear Tire 150/80B16 77H Blackwall — Aramid‑Belted, Heavy‑Duty Touring

The Shinko SR777 HD 150/80B16 77H is a heavy‑duty, aramid‑belted rear motorcycle tire built for cruisers and touring rigs that need extra load capacity and long mileage.

This rear tire is designed for riders who carry passengers or luggage and want a stable, long‑lasting replacement for V‑Twin and metric cruiser motorcycles. Its reinforced carcass and aramid belting add structural strength, while a tubeless blackwall design keeps installation straightforward and serviceable on many common cruiser wheels. The SR777 HD targets touring performance rather than sport handling—prioritizing durability, load capability and consistent wear over aggressive corner grip.

How does the SR777 HD improve stability on long rides?

The tire’s reinforced carcass and heavier belting reduce flex under load, which translates to steadier handling at highway speeds and when carrying weight. That structural rigidity helps prevent irregular wear and keeps the bike tracking true during extended touring miles.

• Aramid belt construction for increased carcass strength
• 4‑ and 6‑ply rated sizes to match heavier cruiser setups
• Reinforced sidewalls that minimize flex under load
• Consistent profile for predictable steering at speed

Which bikes and setups is this 150/80B16 tire compatible with?

The 150/80B16 size fits a wide range of V‑Twin and metric cruiser rear applications—commonly used on mid‑ to large‑displacement cruisers. It's engineered as a direct replacement fitment for bikes that accept 16‑inch rear wheels and need a heavier‑duty touring tire.

• Specifically made for many V‑Twin and metric cruiser models
• Designed for 16" rear wheel applications (150/80B16 sizing)
• Suitable for bikes with passenger or luggage loads
• Tubeless construction for modern cruiser rims

What are the load, ply and speed ratings I need to know?

The SR777 HD comes in multiple ply ratings depending on size—some are 4‑ply rated, others 6‑ply—to provide appropriate load carrying for different cruiser weights. The listed 150/80B16 77H is H‑rated for speeds up to 130 mph and built to handle the extra stresses of touring and heavy loads without premature failure.

• Aramid belting for higher load capacity and durability
• 4‑ and 6‑ply rated carcass options across size range
• 150/80B16 available with a 77H speed/load rating
• Tubeless blackwall construction for common cruiser wheels

How does this tire perform over high mileage and heavy touring use?

The tyre's compound and reinforced build are optimized to resist accelerated wear under weight and long distances, so riders see extended tread life compared with standard cruiser tyres. While not a sport‑oriented compound, it balances wear longevity and stability to suit touring usage patterns.

• Heavier belting reduces carcass fatigue over long miles
• Reinforced construction resists deformation from loads
• Designed for even tread wear on sustained highway use
• Blackwall finish for a classic cruiser appearance

Who is this for: The Shinko SR777 HD 150/80B16 77H is for cruiser and touring riders who prioritize load capacity, carcass strength and long service life over sport handling. If you ride a V‑Twin or metric cruiser with a 16‑inch rear wheel and often carry a passenger, luggage or run heavier setups, this tire is built to give stable highway performance and extended mileage while matching the traditional cruiser look.
