Yokohama Advan Sport V103S RFT (225/45R17 91Y)

The Flagship Performance Run-Flat. High-Speed Precision and Safety.

The V103S RFT is designed to maintain the “planted” steering feel and high-speed stability of a performance car even after a complete loss of air pressure. The 91Y rating confirms its capability for speeds up to 300 km/h, ensuring it can handle the stress of high-performance luxury saloons.

✨ Key Technical Features

• 🛡️ ZPS Run-Flat Security:

  The Zero Pressure System (ZPS) uses a reinforced, heat-resistant sidewall that supports the car’s weight without air. This allows you to continue driving for up to 80 km at 80 km/h, making it ideal for the KPE or PIE tunnels where stopping is dangerous.

• 🏁 Exclusive Rubber Compound:

  Yokohama developed this high-grip compound in conjunction with world-leading supercar manufacturers. It maintains its flexibility and “sticky” properties across a wide temperature range, providing maximum traction during aggressive dry cornering.

• 🏗️ Rayon Carcass Construction:

  Instead of standard nylon, the V103S utilizes a high-rigidity Rayon body ply. This material is exceptionally durable under high loading stress, ensuring the tyre maintains its precise shape and surgical steering response at extreme speeds.

• 📐 Asymmetric Tread Architecture:

  The pattern is divided into a stiff outboard shoulder for cornering stability and an inboard zone optimized for water drainage. This dual-purpose design ensures the tyre feels stable on dry expressways and safe during heavy tropical rain.

• 🔇 5-Pitch Variation Pattern:

  To counter the naturally high road noise of a low-profile run-flat tyre, Yokohama utilized five different tread block sizes. This breaks up air resonance, leading to a quieter cabin experience than many other performance run-flats.

📊 Performance Summary

• Dry Grip: ⭐⭐⭐⭐⭐ (Class-leading ADVAN performance)

• Security: ⭐⭐⭐⭐⭐ (Trusted run-flat technology)
