Nokian WR A4 RunFlat Tire - Unmatched Winter Performance

Exceptional Winter Grip

Experience advanced winter traction with the Nokian WR A4 RunFlat tire, designed to excel on dry, wet, and snow-covered roads. Its innovative functional performance sipes ensure superior grip and handling, making it an ideal choice for winter driving.

High-Performance Stability

The Nokian WR A4 offers extreme stability and balanced high-performance, providing maximum comfort during your journey. Each tread block and sipe has a computer-optimized role, ensuring excellent grip and handling. The stiff outer shoulder, centipede sipes in the center area, and zone-optimized sipes work in harmony to deliver a controlled and comfortable ride.

Centipede Sipes for Precise Handling

The center area of the tire is dominated by a solid longitudinal rib composed of tread blocks with jagged sipes, reminiscent of centipede footprints. These 3-dimensional centipede sipes provide maximum contact area and adapt to various curve radii, enhancing grip on snow and slush while improving control.

Performance Traction Silica Rubber Compound

The innovative rubber compound, featuring natural rubber, silica, and rapeseed oil, offers precise grip, excellent wear resistance, and reduced fuel consumption. This advanced blend enhances driving stability and durability, with rapeseed oil contributing to tear resistance, making the tire highly resistant to wear, impacts, and cuts. The high content of natural rubber and rapeseed oil ensures consistent winter grip, even as temperatures fluctuate and mileage increases.

Low Rolling Resistance

Enjoy reduced fuel consumption thanks to the tire's extremely low rolling resistance.

Profile Groove Enhancers for Excellent Handling

The tread shoulder blocks are supported by steep profile groove enhancers, increasing strength and improving handling.

Snow Claws for Strong Snow Grip

Snow claws on the longitudinal grooves of the tread blocks provide the necessary grip on winter roads, digging firmly into soft snow and surfaces.

Nokian Tyres Coanda Technology

Effectively combat aquaplaning with the curved, ramp-like design of the inner shoulder tread blocks, which channels water flow rapidly from the longitudinal groove to the transverse groove. These outstanding aquaplaning properties are maintained even as the tread wears.

Silent Sidewall Technology for Enhanced Comfort

A custom-designed special rubber compound between the sidewall and tread filters out noise and vibrations from the steel belt, preventing sound waves from penetrating the rim and entering the car's interior.

Special Clinch Rubber Compound

This compound flexibly presses against the rim flange, ensuring increased durability in the bead area. The innovation effectively reduces in-vehicle noise by dampening vibrations from the tire body.

Polished Grooves for Safety and Elegance

The polished longitudinal and transverse grooves facilitate the removal of snow and slush, enhancing both safety and aesthetic appeal.

New Nokian WR A4 – Forget the Forecasts 

• Advanced winter grip on dry, wet and snow-covered roads due to Functional Performance Siping
• Extremely stable and balanced high-speed performance
• Maximum comfort

Main innovations:

Functional Performance Siping. More winter grip, better steering feel. Each tread block and sipe in the stylish tread pattern has a precise shape and role, and this can be felt in the excellent grip and handling properties. The stiff outer shoulder, the Centipede Siping in the centre area and the zone-optimised siping all form a controlled combination that allows the Nokian WR A4 to roll safely and comfortably in varying Central European winter weather.

Centipede Siping. Maximum snow grip, precise handling. The centre area is dominated by a sturdy longitudinal rib consisting of tread blocks with jagged sipes that resemble the footprints of a centipede. The staggered 3-dimensional Centipede Siping offers maximum contact surface and works with full effect at different turning angles, increasing grip on snow and slush and improving control.

Performance Traction Silica rubber compound. Precise grip, excellent wear resistance, low fuel consumption. The rubber compound, which contains natural rubber, silica and canola oil, ensures excellent winter grip. This state-of-the-art compound innovation also improves driving stability and wear resistance. Canola oil provides tear strength. Tear strength makes the tyre extremely resistant to wear, impacts and punctures. The large amounts of natural rubber and rapeseed oil ensure that the excellent winter grip properties remain the same even as temperatures change and the kilometres add up. Extremely low rolling resistance results in low fuel consumption.

Groove Lifts. Excellent handling. The tread blocks on the tyre shoulders are supported by steep groove lifts that increase stiffness and improve handling.

Snow Claws. Strong snow grip. Snow Claws were shaped on the longitudinal grooves of the tread blocks to provide much-needed grip on winter roads. Snow Claws grip the surface relentlessly on soft snow and in soft terrain.

Nokian Tyres Coanda Technology. Effective aquaplaning prevention. The curved, ramp-like design of the tread blocks on the inner and outer shoulder guides and accelerates the flow of water from the longitudinal grooves into the transverse grooves. The excellent aquaplaning prevention properties are retained, even as the tyre wears down.

Silent Sidewall Technology. More driving comfort. The tailored special rubber compound between the sidewall and tread actively filters the sound and vibration originating from the driving surface, preventing the passage of harmful sound waves that irritate the human ear through the sidewall into the passenger compartment.

Special Clinch rubber compound. Optimised durability, lower rolling noise. The rubber compound presses flexibly against the wheel flange, providing the bead area with more durability. The innovation also effectively minimises the interior noise, since it dampens the vibrations from the tyre body, preventing them from passing into the tyre and further inside the vehicle.

Polished Grooves. Safety and elegance. The polished longitudinal and lateral grooves facilitatethe removal of snow and slush.
