Description

Greentrac Quest X 215/55 ZR17 94W is a high-performance, all-season tire designed for passenger vehicles. Here's a detailed description of its features and specifications:

Key Features:

• Asymmetric Tread Design: This design features different patterns on the inner and outer sides of the tire. The outer longitudinal grooves are specifically designed to enhance wet grip and handling.  
• Excellent Wet Grip (A Rating): The large groove design ensures optimal performance on wet roads. The new formula with melt polymerized styrene-butadiene and silicon further contributes to excellent wet grip.
• Low Noise: A 5-pitch and multi-steel disc pattern design effectively reduces rolling noise for a more comfortable driving experience.  
• Fuel Efficient Performance: The silicon-based compound helps to lower rolling resistance, leading to improved fuel efficiency.  
• All-Season Traction: The asymmetric tread pattern, along with optimal sipe and groove placement and a special compound, provides good traction in dry, wet, and light winter conditions.  
• Enhanced Controllability: Continuous center ribs in the asymmetric pattern optimize road contact, improving steering responsiveness and driving stability.
• High-Speed Durability: The heat-resistant compound and even pressure distribution across the footprint enhance the tire's durability at high speeds.  
• Comfortable Ride: The 5-pitch and multi-steel disc pattern also contribute to reducing road noise and vibrations, enhancing driving comfort.  
• Rim Protector: Some sources indicate the presence of a rim protector to safeguard wheels from curb damage.  

Specifications:

• Tire Size: 215/55 ZR17
  • 215: Section width in millimeters.
  • 55: Aspect ratio (sidewall height as a percentage of section width).  
  • ZR17: Indicates a radial construction and that the tire is designed for high-performance vehicles with a 17-inch wheel diameter. The "Z" in ZR indicates a speed rating capability exceeding 240 km/h (149 mph), while the "R" denotes radial construction.
• Load Index: 94
  • Indicates the maximum weight each tire can carry, which is 670 kg (1477 lbs).
• Speed Rating: W
  • Denotes the maximum safe operating speed of 270 km/h (168 mph).
• Type: Summer/All Season (marketed as both, suggesting good performance in various conditions but potentially not ideal for severe winter).
• Construction: Radial
• EU Tire Labeling: Typically shows a rating of C for rolling resistance and A for wet grip, with a noise level of B at 70 dB. However, these ratings can vary slightly.  

In Summary:

The Greentrac Quest X 215/55 ZR17 94W is a high-performance all-season tire that appears to offer a strong emphasis on wet grip (often achieving an "A" rating on the EU label). It also aims to provide good handling, fuel efficiency, and a comfortable, quiet ride. The "W" speed rating and "ZR" designation indicate its suitability for vehicles capable of higher speeds.
