The Nokian Hakka H and Nokian Hakka Z summer tyres have been collecting victories in tests both in Finland and abroad. In Finland, the tyres took first place in Tekniikan Maailma's summer tyres testing.
They also won the tests carried out by Auto, Motor + Sport in Sweden, Norway’s Motor magazine and Za Rulem, a Russian motoring publication. Nokian Hakka i3 also won a test performed by the Auto Center magazine in Ukraine.
The Y-speed class (300 km/h) Nokian Hakka Z tyre of size 225/40 R18 was also involved in the same test as the H-class tyres. The overall grade of the Nokian Hakka Z was the best of the entire test at 9.1.
Driving qualities such as handling, swerving and braking were tested on wet and dry asphalt. In these tests, the 18-inch Nokian Hakka Z was in a class of its own, even defeating all the best 16-inch H-class tyres.
You can drive approximately 50 kilometres on a flat tyre, if the car is fully loaded. If the car is only carrying the driver, the transition drive can be up to 150 kilometres.
Nokian Tyres recommends a maximum speed of 80 kilometres per hour. Under very slippery conditions, the speed should be kept at approximately 50 km/h.
For safety reasons, run flat tyres can only be mounted on cars equipped with air pressure monitoring that is integrated into the IT system, or some other system that warns of changes in tyre pressure changes, and a driving stability management system (ESP).
