The excellent, balanced grip of the sturdy Hakkapeliitta C4 is ensured by state-of-the-art stud technology from the world's northernmost tire. For heavy vans in particular, maximizing lateral grip is important in order to retain control of the high-performance vehicle during sudden evasions and braking. The square stud made of stainless steel grips firmly and will last even as the miles add up. The new stud is more resistant to corrosion and wear caused by salted roads and moisture. Safe winter grip is also helped by the increased number of studs and the various sipe depths and sizes on the tread blocks.
