Expert summary

This is currently the best rated tyre we have and there is a reason for it - it combines sportiness on snow and dry and very good safety margins on the wet. It’s designed to maintain the joy of driving, even on winter tyres, but still manages to be safe at all times. 100% recommended.

Expert summary

Blizzak has always been a winter tire focused on wet conditions, but with its sixth model, Bridgestone has promised improved snow performance and reduced rolling resistance. Early tests suggest they have delivered on these promises—Blizzak 6 is unmatched in wet conditions and excels on snow, making it ideal not just for city climates.

Expert summary

Continental winter tires have been winning tire tests for many years, and the 870P is no exception. The “P” stands for performance, but don’t be mistaken, its rolling resistance is also praised, making it ideal for EVs. A well-balanced tire.
