Description

Greentrac Quest X 225/55 ZR18 98W is a high-performance, all-season tire designed for passenger vehicles, offering a combination of excellent wet grip, low noise, and fuel efficiency. Here's a detailed description of its features and specifications:  

Key Features:

• Asymmetric Tread Design: Features a distinct inner and outer tread pattern to optimize performance in various conditions. The outer longitudinal grooves are specifically designed to enhance wet grip and handling.  
• Excellent Wet Grip (EU Label A): The large groove design and an advanced compound with melt-polymerized styrene-butadiene and silicon provide exceptional grip on wet roads, often achieving an "A" rating on the EU tire label.  
• Low Noise: A 5-pitch and multi-steel disc pattern design effectively reduces rolling noise, contributing to a quieter and more comfortable ride.  
• Fuel Efficient Performance: The silicon-based compound helps to lower the tire's rolling resistance, leading to improved fuel economy.  
• All-Season Traction: The asymmetric tread pattern, along with optimized sipes and grooves and a specialized compound, offers good traction in dry, wet, and light winter conditions.  
• Enhanced Controllability: Continuous center ribs in the asymmetric pattern maximize the tire's contact with the road, resulting in improved steering responsiveness and enhanced driving stability.  
• High-Speed Durability: A heat-resistant compound and even pressure distribution across the tire's footprint enhance its durability and performance at high speeds.  
• Comfortable Ride: The 5-pitch and multi-steel disc pattern also contribute to reducing road noise and vibrations, enhancing overall driving comfort.  
• Rim Protector: While some sources for other sizes of the Quest X mention a rim protector, information specifically for the 225/55 ZR18 98W is less consistent. One listing explicitly states "Rim NOT INCLUDED," referring to the wheel itself, which implies the tire may have a rim protector, but it's not guaranteed. It's best to check with the specific vendor you are purchasing from to confirm if this tire includes a rim protector.  

Specifications:

• Tire Size: 225/55 ZR18
  • 225: Section width in millimeters.
  • 55: Aspect ratio (sidewall height as a percentage of section width).  
  • ZR18: Radial construction designed for high-performance vehicles with an 18-inch wheel diameter. The "Z" indicates a speed rating capability exceeding 240 km/h (149 mph), and "R" denotes radial construction.  
• Load Index: 98
  • Indicates the maximum weight each tire can carry, which is 750 kg (1653 lbs). This is a higher load capacity than the 95 load index of the 225/45 ZR18 version.
• Speed Rating: W
  • Denotes the maximum safe operating speed of 270 km/h (168 mph).  
• Type: Summer/All Season (designed for a wide range of conditions but may not be 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 have slight variations.  

In Summary:

The Greentrac Quest X 225/55 ZR18 98W is a high-performance all-season tire that prioritizes excellent wet grip (often with an "A" EU rating). It also offers good handling, fuel efficiency, a quiet ride, and a higher load-carrying capacity compared to the 225/45 ZR18 version. The "W" speed rating and "ZR" designation make it suitable for vehicles capable of higher speeds. Whether it includes a rim protector should be verified with the seller.
