Tire Specifications: Haida HD 668 215/65 R17 99V

• Tire Type:Summer Tire
  • Specifically designed for warmer temperatures, providing superior performance on dry and wet roads but not suited for snow or icy conditions. The tire compound maintains flexibility in warmer weather, maximizing grip and handling.
• Size:215/65 R17
  • 215: The tire width is 215 mm from sidewall to sidewall.
  • 65: The aspect ratio is 65%, meaning the height of the sidewall is 65% of the tire's width. In this case, the sidewall height is approximately 139.75 mm.
  • R: Radial construction, which means the tire's internal construction is designed for a flexible and durable sidewall with radial ply layers arranged perpendicular to the center of the tire. This helps with stability, comfort, and fuel efficiency.
  • 17: This tire is designed to fit a 17-inch rim.
• Load Index:99
  • The load index of 99 indicates that each tire can carry a maximum load of 775 kg (1,710 lbs) when inflated to the recommended pressure.
• Speed Rating:V
  • A speed rating of V allows the tire to handle speeds up to 240 km/h (149 mph). This high-speed capability is typical for performance tires and provides better control at higher speeds.

• Dry Performance:
  • The tire is engineered with a robust tread pattern and high-performance compound that enhances grip and stability on dry roads, providing improved braking and cornering performance.
• Fuel Efficiency (Rating D):
  • The D fuel efficiency rating indicates moderate rolling resistance. This helps balance between performance and fuel economy, reducing fuel consumption while ensuring safe handling.
• Noise Level:
  • With a B noise rating and producing a sound level of 71 dB, the Haida HD668 is relatively quiet for a high-performance tire, ensuring a comfortable ride without excessive road noise.
• Tread Design:
  • The tire features a specialized tread pattern optimized for dry and wet conditions. This includes wide circumferential grooves that evacuate water efficiently, enhancing wet performance and preventing hydroplaning. The tread blocks are designed for solid contact with the road, improving traction and stability.
• Durability:
  • Built with a durable tread compound, the HD668 is designed to offer long-lasting performance while resisting uneven wear, contributing to a longer tread life. It is made with a strong sidewall construction that adds resilience and protects against impacts and abrasions.
• Comfort:
  • The advanced tread design and optimized rubber formulation work together to provide a smooth and comfortable driving experience, reducing road vibrations and enhancing overall ride quality.

Key Technologies: Haida HD 668 215/65 R17 99V

• Performance-Optimized Tread Compound:
  • The tire uses a high-quality rubber blend that maintains flexibility in warm conditions, providing excellent grip on both dry and wet surfaces. The compound helps the tire perform optimally in warmer temperatures, making it ideal for summer conditions.
• Enhanced Stability:
  • The Haida HD668 uses a stiffened tread block pattern that offers improved stability during high-speed driving, enhancing cornering abilities and overall vehicle handling.
• Hydroplaning Resistance:
  • The deep, wide grooves in the tire’s tread work to channel water away from the contact patch, reducing the chances of hydroplaning during heavy rainfall.

Usage:

• Season: Summer tire; not suited for snowy or icy conditions.
• Ideal for: Passenger cars, crossovers, and SUVs used in warmer climates.

Warranty & Longevity:

• The Haida HD668 comes with a manufacturer warranty that typically covers defects in materials and workmanship. The tire’s expected lifespan is generally long due to the durable rubber compounds and solid construction. However, it is important to maintain proper tire inflation and regularly check tread depth for optimal performance.
