NOKIAN 225/45RF18 91Y POWERPROOF RFT 68EA

NOKIAN 225/45RF18 91Y POWERPROOF RFT

The 225/45RF18 91Y PowerProof RFT is a high‑performance, run‑flat tire engineered for drivers who demand safety, comfort and durability in summer conditions. Its design incorporates advanced rubber compounds, reinforced sidewalls and an optimized tread pattern to deliver reliable traction on both dry and wet roads.

Tire Dimensions & Construction

• Overall diameter: 225/45RF18 – a width of 225 mm, aspect ratio of 45%, radial construction (R) and a 18‑inch rim size.
• Load index: 91, which corresponds to a maximum load capacity of 615 kg per tire.
• Speed rating: Y, allowing safe operation up to 300 km/h (186 mph).
• Run‑flat technology: RFT (RunFlat Technology) – the tire can maintain structural integrity after a puncture, enabling you to drive safely for at least 80 km at reduced speed.

Performance Characteristics

The PowerProof RFT is specifically designed for summer use, providing excellent grip on hot asphalt and efficient handling in light rain. Its tread layout features:

• Wide circumferential grooves that channel water away, reducing hydroplaning risk.
• Symmetrical pattern with optimized sipes for enhanced cornering stability.
• High‑performance rubber compound that balances traction and wear resistance.

Noise Level

The tire’s noise emission is measured at 68 dB(A), which places it in the moderate range for summer tires. This level ensures a quiet ride without compromising on grip or durability.

Key Features & Benefits

• Run‑Flat Capability: Drive safely after a puncture, eliminating the need for immediate roadside assistance in many situations.
• High Speed Rating (Y): Suitable for high-performance vehicles and drivers who enjoy spirited driving.
• Summer Season Design: Optimized tread pattern and rubber compound for hot weather performance.
• Durable Construction: Reinforced sidewalls and robust carcass protect against punctures and extend tire life.
• Comfort & Handling: Balanced ride quality with responsive steering feedback.

Ideal Vehicle Applications

The 225/45RF18 91Y PowerProof RFT is compatible with a wide range of passenger cars and SUVs that require an 18‑inch rim. It is particularly well suited for:

• Sedan models that prioritize performance and safety.
• Compact SUVs seeking reliable summer traction.
• High‑performance vehicles where speed rating Y is mandatory.

Installation & Maintenance Tips

1. Always use a tire pressure gauge to maintain the recommended inflation level; underinflation can increase noise and wear.
2. Avoid driving on severely damaged roads for extended periods, as this may compromise run‑flat integrity.
3. Inspect tread depth regularly; replace when it reaches the minimum legal limit.
4. Store tires in a cool, dry place to preserve rubber properties between uses.

Conclusion

The NOKIAN 225/45RF18 91Y PowerProof RFT delivers a compelling blend of safety, performance and comfort for summer driving. Its run‑flat technology, high speed rating and moderate noise level make it an excellent choice for drivers who value both reliability and dynamic handling.
