Yokohama Advan Sport V105S RFT (225/45R18 91Y Y26)

“Track-Bred Precision, Zero-Pressure Security.” Fresh 2026 Production.

The V105S was developed and refined at the Nürburgring to deliver a “driver-centric” experience. While run-flats are historically known for being overly stiff, the 2026-spec V105S utilizes Yokohama’s most advanced ZPS (Zero Pressure System) sidewall construction, which uses a specialized low-heat-generating compound to provide a more compliant and comfortable ride during daily urban driving.

✨ Key 2026 Technical Features

• 🛡️ ZPS (Zero Pressure System) Safety:

  Featuring reinforced, high-durability sidewalls that support the vehicle’s weight even with a total loss of air. This allows you to continue driving for up to 80 km at a maximum speed of 80 km/h, ensuring you can safely reach home or a workshop without stopping on dangerous expressways like the PIE or KPE.

• 🏎️ Matrix Body Ply Structure:

  A racing-derived carcass architecture that enhances lateral rigidity. This technology provides razor-sharp steering response, eliminating the “mushy” feel often found in standard touring tyres and ensuring the car stays composed during high-speed lane changes.

• 🧪 5S Sport Compound with Orange Oil:

  The 2026 compound is enriched with natural Orange Oil to keep the rubber flexible at a micro-level. This ensures Elite Class-A/B wet grip, providing the high levels of friction needed for short stopping distances during intense Singaporean afternoon monsoons.

• 🏁 Asymmetric Sport Tread:

  The tread features a solid outer “Power Zone” for maximum cornering stability and an inner “Wet Zone” with three wide circumferential grooves. This design provides extraordinary resistance to hydroplaning, keeping the tyre “glued” to the asphalt in all conditions.

• 🔇 Mound Profile & Silent Sipes:

  Unlike older run-flats, the V105S uses a “Mound Profile” to distribute road pressure evenly and “Silent Sipes” along the ribs to disrupt air resonance. This results in a refined cabin environment that is significantly quieter than traditional UHP run-flat competitors.

📊 Performance Summary

• Dry Handling: ⭐⭐⭐⭐⭐ (Surgical precision and grip)

• Safety (RFT): ⭐⭐⭐⭐⭐ (Maximum security against blowouts)

• Wet Safety: ⭐⭐⭐⭐⭐ (Elite Class-A drainage and braking)

• Ride Quality: ⭐⭐⭐⭐ (Firm but highly refined for a run-flat)

The Yokohama Advan Sport V105S RFT is the definitive “no-compromise” safety choice for 2026. It is the best option for your BMW 3 Series or Mercedes-Benz if you want a fresh, high-performance tyre that allows you to drive safely even after a puncture, without sacrificing the steering feel of a true Japanese sports tyre.
