✨ Key NF1 Performance Technologies
-
🏎️ Impulse Control Compound:
This version features a highly refined tread compound with an extra silica load. It is designed to heat up quickly to its optimal operating temperature, providing immediate “bite” and grip during high-speed cornering on the North-South Highway.
-
🛑 ActiveBraking Technology:
Under heavy braking loads, the tread ribs expand their contact area with the road. For heavy, high-performance vehicles like the Porsche Taycan, this ensures shorter braking distances and keeps the car stable during emergency stops.
-
🏗️ Power Cushion Structure:
The Asy5 features a reinforced “coupling” between the carcass and the tread pattern. This leads to extremely precise force transfer, meaning the driver feels more “connected” to the road through the steering wheel, even at triple-digit speeds.
-
🌧️ Wet Handling Mastery:
Despite its wide 305mm footprint (which usually risks hydroplaning), the Asy5 uses wet-optimized polymers and deep longitudinal grooves to flush away water instantly. It maintains a Class A wet grip rating, ensuring safety during Singapore’s intense afternoon storms.
-
🔇 Low-Noise Performance:
Because the NF1 spec is often used for electric vehicles like the Taycan, Goodyear optimized the pitch sequence to reduce “tread growl.” At 72dB, it is remarkably quiet for a tyre of this massive width, preserving cabin luxury.
📊 Performance Summary
-
Dry Grip: ⭐⭐⭐⭐⭐ (Exceptional mechanical traction)
-
Steering Feedback: ⭐⭐⭐⭐⭐ (Razor-sharp and predictable)
-
Wet Safety: ⭐⭐⭐⭐⭐ (Benchmark braking performance)
-
Road Noise: ⭐⭐⭐⭐ (Refined for a supercar tyre)
The Goodyear F1 Asy5 NF1 is the essential choice for 2026 if you drive a Porsche and want to maintain the factory-standard handling and safety certifications. It provides the perfect balance of “weekend track” grip and “daily driver” comfort.
