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.

Did you know ...?

245/40 R21 doesn't belong to the most popular dimensions for winter tyres - there are tyre models available, which can be compared to 325/30 R21, 155/60 R15, 155/65 R13. Let's break down the sizing - 40 is height of the tyre, which is calculated as 40% of the tyre width (245mm), which means the sidewall height has 98 mm. The wheel diameter is R21, which means it fits to a 21 inch/533.4mm diameter wheel. The total circumference of the tyre is mm, which is very similar to 205/55 R16(1985.17 mm), 275/35 R18(2041.09 mm), 205/75 R16(2242.78 mm), 275/40 R22(2446.67 mm), 215/45 R18(2044.23 mm), 275/65 R17(2479.66 mm), 215/65 R15(2075.02 mm).
