New Nokian Nordman summer tires: Nokian Nordman SZ2 offers precise handling, Nokian Nordman S2 SUV is a durable companion

Safety and reliability are the features that drivers want the most for their summer tires in the north. The combination of rutted roads, scorching heat, and sudden rain showers places high demands on summer tires.

Safety and reliability are the features that drivers want the most for their summer tires in the north. The combination of rutted roads, scorching heat, and sudden rain showers places high demands on summer tires. 
 
Nokian Tyres – the world’s northernmost tire manufacturer – offers Nokian Nordman summer tires that have been created to withstand rapid temperature variations and driving on rough roads full of potholes. The new Nokian Nordman SZ2, designed for high-speed driving, remains easy to control and handle on wet and dry surfaces alike. Tailor-made for SUVs, the Nokian Nordman S2 SUV is an efficient and safe choice for the urban jungle and forest trails alike. 
 
- In line with our product philosophy, the Nokian Nordman tires combine safety and durability into a balanced end result. The technical solutions and innovations perfected over millions of kilometers of testing guarantee a long service life, says Product Development Manager Jarno Röytiö from Nokian Tyres.  
 
The Nokian Nordman summer tires represent the B segment in Nokian Tyres’ comprehensive and versatile selection of summer products; in terms of value for money, it is an excellent alternative to the Nokian Hakka summer tire family that represents the absolute highest in premium performance. The new products will be available at retailers in spring 2021. 
 
Nokian Nordman SZ2 – Safely and precisely even at the extremes 
 
The new Nokian Nordman SZ2 summer tire offers convincingly precise handling. This new high-performance product can retain control on asphalt and gravel alike. Developed for heavy-duty use and higher speeds, this new product is in the UHP category, which is the top tier for passenger car tires. Its size selection comprises 21 products from 16 to 20 inches, in the speed categories V (240 km/h), W (270 km/h), and Y (300 km/h).

The tread shape perfectly supports the precise handling of this sporty tire. The rigid inside and outside shoulder areas connect to tread blocks that are bound together by longitudinal ribs. The wide, massive ribs stiffen the tire and reduce the movement of the tread blocks during road contact. The tread model is very rigid, which translates into good control and handling at higher speeds. The Nokian Nordman SZ2 immediately responds to steering, which is an essential requirement for safe operation at the extreme limits. 
 
The longitudinal ribs next to the inner shoulder are dominated by deep lateral grooves that stabilize handling. At the same time, the Hydro Grooves innovation effectively prevents aquaplaning by storing water from between the surface and the tire, and by guiding the water into the longitudinal grooves. To combat aquaplaning, separate Swoop grooves were also shaped in the transversal main grooves on the outer shoulder. These elliptical slots store more water as the volume of the transversal grooves increases. The shape ensures that the firm tire has excellent wet grip, even when worn. 
 
Care-free, comfortable driving 
 
- Even drivers who are used to higher speeds can rely on the Nokian Nordman SZ2 for years of service, even as the tire gets older and wears down. The tread compound was custom-made to withstand the stress from poorly maintained roads. The rubber compound functions along a wide temperature range, improving wet grip both during the early spring mornings and the dark fall nights. The cut-resistant compound also enhances driving comfort by damping the noise generated by rough asphalt, Röytiö assures us. 
 
The extremely stiff steel belt pack, combined with a double body structure, is made of high-strength steel wire; the tensile strength of a single wire corresponds to a mass of approx. 2,400 kg. A single tire has nearly 2.5 kilometers of steel wire. 
 
The hemispherical indentations, reminiscent of a golf ball pattern, on the walls of the transverse ribs provide additional driving comfort. This Silent Groove Design innovation controls the interior noise and passing noise of the vehicle. 
 
Nokian Nordman S2 SUV – Efficient and comfortable 
 
Tailored for versatile SUV use, the new Nokian Nordman S2 SUV has a charming character, can withstand the roughest roads, and saves fuel. Thanks to its excellent durability, the sporty tire keeps on going.

The comprehensive size selection is aimed at the ever-growing SUV market, and it consists of a total of 26 products with sizes from 16 to 19 inches. The speed ratings for the new products are T (190 km/h), H (210 km/h), and V (240 km/h), meaning that the Nokian Nordman S2 SUV covers nearly all of the popular SUV models that are sold in the Nordic countries. The wide selection also includes several special products that are marked XL for the highest possible load capacity. 
 
The asymmetrical tread pattern adds to the driving comfort and makes the steering precise. The grooved, or siped, block patterns on the shoulder areas, the varied opening of the grooves, and the differently sized tread blocks with risers support the rigidity and flexibility of the tread pattern, allowing it to suit different driving scenarios.  
 
The wear resistance of the Nokian Nordman S2 SUV, a steady performer even at high speeds, was fine-tuned with a tough and strong tread compound that can withstand potholes, impacts, and wear.  
 
Balanced and light rolling – even off the road  

Several new innovations provide added safety for rainy weather, which is an essential part of the Northern summer. The bullet-shaped Trumpet grooves store water from between the tire and the road, accelerating its flow from the main grooves toward the transverse grooves and maximizing grip even on rain-soaked roads. 
 
- The Nokian Nordman S2 SUV offers excellent grip on dry and wet roads. It is the right choice for drivers who value effective and safe driving but who also want to enjoy the characteristics of their SUVs on forest roads and urban traffic alike. The Off-Road Claws grip the road surface in a controlled manner, improving grip during traction and acceleration. Stone Ejectors prevent rocks from becoming wedged in the grooves and tread blocks. 
 
As before, the tread surfaces of both new products have Nokian Tyres’ patented Driving Safety Indicator (DSI). The water drop symbol disappears at the point where less than four millimeters of tread remain, thereby indicating an increased risk for aquaplaning. During a tire change, the sidewall information area can be used to record the correct inflation pressures, the usage location for the tires, and the tightening torque of the wheel nuts. 
 
Nokian Nordman SZ2 – Precise and safe handling  

  • Stable, precise, and quiet 
  • Exact and easy to control, even at the extremes 
  • Withstands wear from rough roads very well 

Main innovations: 
 
Hydro Grooves. Better driving stability, wet grip, and aquaplaning properties. The longitudinal ribs next to the inner shoulder are dominated by deep lateral grooves that stabilize handling. At the same time, the new Hydro Grooves innovation effectively prevents aquaplaning by storing water from between the surface and the tire, and by guiding the water into the longitudinal grooves. 
 
Swoop Grooves. Effectively prevents aquaplaning. The elliptical slots on the transversal grooves on the inner shoulder store more water, as the volume of the transversal grooves increases. This improves the aquaplaning characteristics. The transversal grooves are also cut to be more open, which accelerates the flow of exhaust water. 
 
Silent Groove Design. More driving comfort. The circular, golf ball-like indentations on the walls of the transversal grooves control the airflow. They prevent the creation of an unpleasant, howling sound. The design makes driving comfortably quiet. It also reduces air resistance and cools the surface of the tire, in turn improving wear resistance.
