Developed specifically for the North American market, the Nokian WR G4 model is the fourth generation of all-season tires, characterized by excellent traction on the sun-scorched summer pavement, high hydroplaning resistance, confident behavior on snow, as well as stable handling response and short stopping distances in various weather conditions. The 2018 model Nokian WR G4 is a premium-class environmentally friendly tire that utilizes the proprietary technologies developed by this Finnish tire maker, which ensure dependable tire performance in the typical weather conditions of North America. First of all, it is about the Coanda technology and the inner shoulder’s fan-like rib pattern with functional tread blocks and Blade Grooves, which efficiently route rain, snow and slush away from the contact surface, increasing the tire’s hydroplaning resistance and its stability on wet pavement. We will also mention here the Snow Claws technology that ensures driving safety on winter surfaces, the 3D Centipede Siping system, which allows the tire to maintain its performance in all directions on snow-covered and mud-ridden roads, and the traversal sipes (Functional Performance Siping), which further boost the tire’s grip and provide crisp steering response. The Nokian WRG4 all-weather rubber compound ensures extra traction and extends tread life. The use of a special rubber compound between the sidewalls and the tread (Silent Sidewall technology) prevents the transmission of noise and vibrations to the rim and to the cabin, making the driving experience more comfortable and enjoyable. The Nokian WR G4 will replace the WR G3 model, which has been produced since 2013, known to the Europeans as a winter tire designed to be fitted on passenger cars to be driven in mild weather conditions. Moreover, it is also worth noting here that the WR G4 tread pattern was essentially borrowed from the Nokian WR A4 model, which has been available on the Central European markets since 2016 as a friction winter tire. And, on top of that, one must also note that the model, which preceded the Nokian WR G4, was being produced in two different tread design versions that in inherited from the Nokian WR A3 (asymmetric) and the Nokian WR D3 (symmetric directional). Whether the same fate awaits the fourth-generation all-weather model is yet unclear, just as whether it will get a modification specifically designed for cars with a high gravity center, presumably called Nokian WR G4 SUV (by analogy with the Nokian WR G3 SUV). The latter is, probably, just a question of time.

According to the manufacturer, the Nokian WR G4 tire model has been tested both at the Nokian test facility in Finland and on test tracks in Germany and Spain, while the tread wear tests were performed in the United States.
