At the same time, the CO2 emissions of the car are smaller. According to ADAC-test both premium tires are especially recommended when tires have enough air, can even rip it through the larger flexing. But also damage such as cracks, dents, or profile outbreaks can cause Frost spalling. Pressure too high reduce the security, also because then the footprint is smaller, less forces can be transferred, and the tyres worn only centrally. The security also depends on the tyre tread. The tread depth indicator of DSI (driving safety indicator) on the Nokian Tyres displays the groove depth as a number from 8 to 2.
An aquaplaning indicator with water drop symbol warns of danger of aquaplaning. Only four millimeters remaining profile will disappear and so indicate an increased risk. Because to prevent aquaplaning and the braking distances in wet conditions short enough, the minimum depth of the main grooves should be four millimeters. Are abraded to the profile to see or have left the tire ungleichmig, the shock absorbers may be defective. The tyre of Nokian Tyres are developed in the demanding conditions of the North, tested and manufactured.
They offer the best performance even under the most extreme conditions. The Expert from Finland is even a satisfaction guarantee: If a buyer for any reason with its new one at an authorized Nokian dealer is not satisfied purchased summer tires, he can exchange there them 14 days against a different set of tires. Mounting and balancing are free of charge. Measure the air pressure always on cold tyres, with heavier load, also a high pressure is required. You will find the correct values on the tank cover or in the operating instructions. In time the driver should check, at best a few days before the holiday, so that, if necessary, enough time for the changing of tires remains.
