The Nokian Powerproof is the company's latest ultra high performance summer tyre. Designed to safely, comfortably and silently adapt to variety of road surfaces, it handles well and offers drivers peace of mind when it comes to high-speed lane changes and sudden braking.
The Powerproof is a completely new generation of summer tyre originally developed for central Europe, where weather conditions and road surfaces vary greatly. As a result of this, it is a tyre that can adapt to a wide variety of driving conditions.
With the Powerproof, balance is key. It provides a winning combination of driving safety, performance and enjoyment through even pressure distribution, stable handling and logical steering. To provide this high quality performance, the Powerproof has various interesting features and utilises a wide range of modern technologies.
Grip & Traction
The Powerproof's Dual Zone Safety technology keeps the tyre's contact surface constant on both dry and wet roads. This enables the tyre to grip the road and adapt to different surfaces more effectively. It also improves the tyre's steering response.
As part of this concept, a "Power Zone" on the outer shoulder of the tyre helps improve handling precision. At the same time, rigid tread blocks combined with sloped grooves helps the Powerproof provide better lateral stability and dry traction.
Many strategically placed grooves serve to improve the Powerproof's wet grip. The tread features four wide, polished grooves running around the tyre's circumference, as well as trapezoidal grooves that divide the centre rib and the inner shoulder rib. They remove water more effectively from the contact patch, which consequently reduces the risk of aquaplaning.
Durability & Strength
The Powerproof has a new, stronger structure and a level of durability suited to an ultra high performance tyre. The design utilises three wide main ribs to increase sturdiness, while the sleek shoulder area further increases stability.
Thanks to its molecular makeup, the Dynamic Grip compound remains flexible and ensures better grip and durability, even when driving at high speeds. The tread's multi-layered structure also reduces rolling resistance and therefore improves fuel efficiency and offers more even wear.
Customers demand high levels of safety and performance from their tyres, but they also refuse to compromise on comfort. That's why Nokian's research and development teams have worked hard to ensure the Powerproof provides excellent ride comfort.
In addition to including hemispherical indentations on the sides of the longitudinal ribs to reduce noise and increase comfort, the Powerfproof also utilises a Silent Groove Design. This is a famous Nokian innovation that reduces both interior noise and external rolling noise.
Moreover, the modern Clinch rubber compound helps to further minimise cabin noise. This is because it reduces the vibrations from the tyre body, preventing them from passing over onto the rim and inside the vehicle.
The Powerproof has a Driving Safety Indicator (DSI). Patented by Nokian, this unique tread wear indicator also features a droplet symbol that appears when the tread wears down to four millimetres. It indicates an increased risk of aquaplaning and alerts drivers clearly to when their tyres need changing.
Research & Development
The development of the Powerproof took four years. Nokian paid special attention to safety, in particular to ensuring controlled handling at high speeds. In fact, the company's Development Manager, Jarno Röytiö, explained how safety is at the forefront of all research and development the company carries out.
Nokian used laboratory testing and computer modelling in the development process of the Powerproof.
Nokian developed the Powerproof's durability through vigorous testing in extreme heat at the company's Spanish testing facilities. At the same time, the tyre's high speed characteristics were refined on German and Spanish test tracks.
Mikka Häkkinen, an F1 World Champion and Nokian Brand Ambassador, contributed his insight and expertise to the development and testing of the Powerproof. He explained how he believes excellent steering feedback is an extremely important characteristic of quality tyres and how being confident in your tyre also brings safety.
