This rubber is NOT for people who prefer peace and quiet in their vehicles. They are mostly spikes and have many of "teeth." Ice Zero is most likely for people who drive outside of major cities, where winter road maintenance is inconsistent or nonexistent. The previous vehicle, the Hakka 7, lost almost 70% of its studs in just two seasons. In four seasons, Ice Zero only lost two "teeth". And in my perspective, Ice Zero drives with a bit more assurance.
