Yokohama Advan Sport V103S RFT (225/50R17 94Y)

The Original UHP Performance Benchmark. Run-Flat Stability.

The V103S was designed with a focus on high-speed stability and structural durability. The ZPS (Zero Pressure System) allows you to drive up to 80 km at 80 km/h after a puncture, providing peace of mind on the PIE/KPE without the need for an immediate roadside stop.

✨ Key Technical Features

• 🛡️ ZPS (Zero Pressure System):

  Features reinforced, heat-resistant sidewalls that support the vehicle’s weight even with no air pressure. This technology is crucial for modern premium cars that do not carry a spare tyre, ensuring you can reach a workshop safely.

• 🏎️ High-Grip Exclusive Compound:

  The V103S utilizes a specialized rubber blend developed in conjunction with supercar manufacturers. It is designed to remain flexible and “sticky” across a wide temperature range, providing maximum dry grip during aggressive cornering.

• 📐 Asymmetric Pattern for “Drivability”:

  The tread is split into four distinct ribs. The large outer shoulder blocks provide the lateral stiffness needed for sharp turn-in, while the inner ribs are optimized for water evacuation and straight-line stability.

• 🌧️ 4 Wide Straight Grooves:

  Deep circumferential channels are engineered to flush water away rapidly. While the V105 improves on this further, the V103S still offers respectable hydroplaning resistance for heavy tropical rain.

• 🏗️ Rayon Carcass Construction:

  Unlike standard nylon-belted tyres, the V103S uses high-rigidity Rayon. This material is more resistant to heat and stress, allowing the tyre to maintain its precise shape even at speeds approaching its 300 km/h limit.

📊 Performance Summary

• Dry Handling: ⭐⭐⭐⭐⭐ (Classic ADVAN precision)

• Run-Flat Security: ⭐⭐⭐⭐⭐ (Trusted ZPS architecture)

• Wet Safety: ⭐⭐⭐⭐ (Reliable, though superseded by V105)

• Ride Comfort: ⭐⭐⭐ (Firm; typical of older-gen run-flats)

The Yokohama Advan Sport V103S is the “classic” choice for 2026. It is ideal if you are replacing the original factory tyres on a performance sedan and want to maintain the exact handling balance and run-flat security intended by the manufacturer.
