Imagine this: during a rainy-day lane change on the highway, your tires grip the road firmly, letting you navigate wet conditions with confidence, saying goodbye to hydroplaning anxiety; on a long-distance drive, the cabin remains as quiet as a library, significantly reducing fatigue after a long day. These are not exclusive features of high-end tires — they are the daily performance of GREENTRAC’s Quest-X. As a global emerging tire brand, Quest-X features EU “A” wet grip certification and Silence Guard™ noise reduction technology, perfectly balancing safety and comfort.
At the 2026 German ADAC summer tire test, Quest-X’s top-level performance in wet handling and noise was validated, making it the preferred choice for tire replacement among domestic and international drivers.
Wet Handling Champion: “Guardian” on Rainy Roads with EU “A” Certification
Wet roads are the greatest hazard during rainy driving, and ADAC assigns a 60% weight to wet performance. In the Lateral Aquaplaning test, Quest-X achieved 3.7 m/s², ranking joint first (tied with Continental PremiumContact 7). This test simulates lane changes or cornering on wet roads and evaluates lateral grip. Quest-X’s high lateral acceleration ensures rapid water drainage, preventing hydroplaning and providing a higher safety margin on water-covered roads. For drivers concerned about rain-slicked surfaces or living in regions with frequent rain, driving with Quest-X turns worry into confidence.
This advantage is supported by Quest-X’s EU top-tier “A” wet grip certification, with a wet grip score G(T) 1.62. Tires with an EU wet grip rating of “A” can shorten braking distances by up to 30% compared to the lowest-rated tires, potentially preventing collisions in daily driving. Quest-X’s exceptional wet performance ensures confident handling and safety for every lane change and brake, making family trips or business commuting more secure.
Noise Control King: Patented Silence Technology for a Serene Ride
Noise is the invisible killer during long-distance driving. In the ADAC test, noise and fuel consumption are the most perceptible metrics to users, carrying the highest weighting. Official results show that Quest-X ranks joint first in both pass-by noise (70.2 dB(A)) and interior noise (1.5 points), with a composite noise score of 2.1 (“gut”/excellent). This demonstrates that Quest-X offers a noise experience on par with top-tier premium tires.
The core technology behind this is Silence Guard™, a patented polyurethane-based foam that absorbs and blocks tire noise transmission. Tests show that at high speeds, tires equipped with Silence Guard™ reduce in-cabin road noise by 2–4 dB on average, with a maximum reduction of 9 dB.
Additionally, the inner side of Quest-X incorporates a patented adhesive layer and fully automated laser cleaning, further reducing tire noise and enhancing driving comfort. Whether on long drives or chatting with family, the overall driving experience is significantly improved.
All-Scenario Performance: More than Safety and Comfort
Quest-X also excels in other key metrics:
Dry braking distance: 36.2 m, rated “Stärke” by ADAC
Fuel consumption: 5.7 L/100 km, EU rolling resistance label C
Predicted mileage: 38,200 km, above average among tested tires
High-speed certification: EU “Y” rating, supporting speeds up to 300 km/h
Whether for urban commuting, family weekend trips, or long-distance drives, Quest-X delivers stable performance while minimizing maintenance or tire replacement needs.
