Bridgestone EMIA has presented the friction winter tire Firestone Winterhawk 4. According to the manufacturer, prior to the release of this new-generation winter tire line, over 20,000 end users were interviewed to guide the development of the new Firestone Winterhawk 4. Thus, the main area that the company focused on during the development of the new model 2020/2021 was optimizing the tire’s grip on wet pavement and snow.
The Firestone Winterhawk 4 got a new tread pattern, yet, at the same time, the designers decided to keep the symmetric and directional properties of the Winterhawk 3 predecessor model. The increased number of drainage grooves on the shoulder made it possible to boost the ice and snow traction, as well as optimize the contact patch for more efficient braking in various winter road conditions.
According to the manufacturer, the Firestone Winterhawk 4 snow traction was increased by 7% compared to the previous-generation model, while the wet stopping distance was cut by 4%. And, while in the former case the results were obtained during the Bridgestone in-company test, the latter was recorded by the test experts of TÜV SÜD.
«Firestone has always delivered value for money tires that offer strong and reliable performance for a safe journey. Above any other, winter is the season that brings the greatest driving challenges» — said Emilio Tiberio, Chief Technical Officer and Chief Operating Officer at Bridgestone EMIA.
The Firestone Winterhawk 4 model, designed to be installed on passenger cars and city SUVs, will be available retail since June 2020. Its selection will be presented by 92 sizes with fitting diameters ranging from 14 to 20 inches, which will cover 92% of the market demand for passenger-car tires, and 81% of the demand for larger tires (with a fitting diameters from 17 inches and higher).
