About Nexen N'Fera SU1 245/45R20 103Y XL

The N'Fera SU1 is a summer ultra-high-performance tyre developed for paved-road passenger-car applications. The 245/45R20 specification uses an asymmetric tread design and reinforced XL construction, combining high-speed capability with handling stability and wet-road traction. 

Ultra-High-Performance Summer Design

The N'Fera SU1 is designed for drivers who want responsive handling and predictable road behaviour from a summer tyre. It is suitable for compatible passenger cars requiring a 245/45R20 fitment.

Asymmetric Tread Pattern

The asymmetric tread design is engineered to balance dry-road handling and wet-road performance. The tread layout helps maintain stable contact with the road while supporting water evacuation through its longitudinal grooves. Nexen identifies the N'Fera SU1 as an asymmetric-pattern tyre. 

Wet-Road Traction

The exact 245/45R20 103Y XL specification is listed with a European wet-grip rating of B. The tread design is intended to help move water away from the contact patch and maintain traction during wet-weather driving. Dry-Road Handling

The N'Fera SU1 is designed for stable handling on dry paved surfaces. Its tread structure and reinforced construction support steering response and vehicle stability during acceleration, braking and cornering.

Extra Load Construction

The 245/45R20 103Y specification uses Extra Load (XL) construction. The 103 load index corresponds to a maximum rated load of 875 kg per tyre under the applicable inflation and operating conditions.

High-Speed Capability

The Y speed rating corresponds to a maximum rated speed of 300 km/h under the applicable tyre load and inflation conditions. Actual vehicle speed should always remain within legal limits and the vehicle manufacturer's recommendations. 

Rim Protection

The exact 245/45R20 103Y XL specification is listed with a rim-protector feature. This feature provides additional protection around the wheel rim against light kerb contact during normal road use. 

The 245/45R20 103Y XL specification is listed with C rolling resistance, B wet grip and B external noise, with an external rolling-noise level of 71 dB. These EU label values are comparative classifications and do not represent guaranteed fuel consumption or cabin noise for every vehicle. 

Dimensions and Load Capacity

The tyre has a nominal section width of 245 mm, a 45% aspect ratio and a 20-inch rim diameter. The 103 load index provides a maximum rated capacity of 875 kg per tyre. One specification database lists an overall diameter of approximately 728 mm for this exact size.

Summer Road Use

The N'Fera SU1 is a summer tyre intended for paved-road use in suitable warmer-weather conditions. It should not be treated as a dedicated winter tyre.

2024 Production

The requested product is specified as a 2024 tyre. The exact production week of an individual tyre should be confirmed from the DOT/date code on its sidewall, because the model and size specification alone cannot establish the manufacturing date of a particular tyre.

Who Should Consider This Tyre?

Nexen N'Fera SU1 245/45R20 103Y XL is suitable for compatible passenger cars requiring this exact fitment. It is designed for drivers looking for a summer UHP tyre with responsive road handling, wet-road traction, high-speed capability and reinforced Extra Load construction.
