What information does the Nokian DSI (Driving Safety Indicator) provide for the driver?
The DSI driving safety indicator displays the remaining tread in millimeters, and tells you when you should replace your tires. It is recommended that the tire be replaced once the “4” has worn away. On some tires, DSI also includes a rain drop symbol. When this has worn away, the tires’ hydroplaning capabilities are no longer optimal, indicating it is time for replacement. Once the “2” has worn away, the tires are no longer safe to drive and should be replaced as soon as possible. Also by monitoring the tread wear, you can get more mileage out of your tires by rotating the positions of the tires between the front and rear axles and even different sides of your vehicle. Frequent rotations evens out the differences in tread wear rates between the different positions on the vehicle.
