Shinko Motorcycle Tires SR777 HD Reflector Rear Tire 180/65B16 — Reinforced Carcass, Reflective Sidewall

The Shinko SR777 HD Reflector 180/65B16 81H is a heavy‑duty cruiser rear tire with a reflective sidewall, reinforced carcass, and aramid belting for improved load capacity and longevity.

This SR777 H.D. Rear tire is engineered for cruisers that need durable, stable rear traction plus a visibility boost at night. It pairs bias construction with heavier aramid belts and a redesigned carcass to increase the tire's load rating and expected mileage. The reflective sidewall element remains subtle in daylight and illuminates when struck by headlights, offering an extra layer of roadside visibility without altering the classic cruiser look.

How does the Reflector sidewall improve rider visibility?

The reflective material is embedded into the sidewall and becomes highly visible when hit by light sources such as car headlights. It doesn’t glow continuously; it activates only under illumination, helping other road users spot your motorcycle from the side or rear. This feature increases conspicuity without changing the tire’s daytime appearance.

• Reflective strip integrated into the sidewall for intermittent high visibility
• Unobtrusive in daylight; lights up under headlight beam
• Helps side-on recognition at intersections and in low light

What load, speed, and construction specs should I expect?

This SR777 H.D. model carries an 81 load index and an H speed rating, suitable for many mid-to-large displacement cruisers. It is a bias‑ply (crossply) tire with heavy‑duty reinforcement and aramid belting for added strength and dimensional stability. The tire is tubeless-ready and is offered in 4- or 6-ply rated configurations depending on exact size.

• Size: 180/65-16, designed as a rear cruiser tire
• Load rating: 81, Speed rating: H
• Construction: Bias with aramid belting and reinforced carcass

How does the reinforced carcass and aramid belting affect performance?

Reinforcing the carcass raises the tire’s load capacity and improves its resistance to deformation under heavy loads or during sustained highway use. Aramid belts add tensile strength at the belt package, which supports even wear, better stability at speed, and potentially longer tread life compared with standard belting. Together, these features make the tire well suited to loaded touring and cruiser use.

• Reinforced carcass for higher load capacity and stability
• Aramid (Kevlar-like) belting for strength and wear resistance
• Designed to maintain shape under load for predictable handling

Is this tire compatible with my cruiser and what sizes are available?

The SR777 H.D. Reflector is made for cruiser motorcycles and is available in several sizes that fit many V‑Twin and metric cruiser frames. Confirm compatibility by checking your motorcycle’s tire placard, owner’s manual, or consulting a tire professional. Size availability varies by market and select sizes feature the reflective sidewall option.
