Description Great winter tyres have studs and tread that work in harmony. When developing the Nokian Hakkapeliitta 4, special attention was paid to the stud concept. The Nokian Hakkapeliitta 4 has 14 rows of studs. The wide distribution of the studs improves grip and reduces tyre noise, while an elastic cushion underneath each stud absorbs stud impact, reduces stud noise and enhances stud durability. The new tyre has over 2,000 gripping, narrow sipes with sharp angles and zigzag patterns for superb ice and snow grip and particular sipe alerters on the edges of the tread to boost the effectiveness of the sipes on slippery roads. The Nokian Hakkapeliitta 4 is also a sporty tyre with ample size ranges in low-profile 16-, 17- and 18-inch tyres. The Nokian Hakkapeliitta 4 is the perfect winter tyre choice for modern, high-performance cars: it is stable and safe and has precise driving qualities it is a tyre that does not compromise safety even in the most demanding conditions.
