The Tyre Reviews Score is the most comprehensive tyre scoring system available. It aggregates professional test data from multiple independent publications, user reviews, and consistency analysis using Bayesian statistical methods, weighted normalisation, and recency-adjusted scoring to produce a single, reliable performance rating.

Methodology & Configuration
Scoring Process
  1. Collect Test Data: Gather results from professional tyre tests across multiple publications. Minimum 1 test(s) required.
  2. Normalize Positions: Convert test positions to percentile scores using exponential weighting (factor: 1.2).
  3. Apply Recency Weighting: More recent tests are weighted higher with a decay rate of 0.95.
  4. Incorporate User Reviews: Factor in user review data (minimum 5 reviews). Weight: 15%.
  5. Bayesian Smoothing: Apply Bayesian prior (score: 7, weight: 1.5) to prevent extreme scores with limited data.
  6. Calculate Final Score: Combine all components using normalization factor of 1.1. Max score with limited data: 9.5.

Top 3 Bridgestone Blizzak WS70 Reviews

Given 78% while driving a SEAT Leon 1.9TDi (195/65 R15) on a combination of roads for 25,000 average miles
It just gripped and gripped and gripped on slush, on snow, was happy on ice too.
Soft compound helped with comfort and noise.
On wet felt squishy and a particular sound was noticeable while on speed/acceleration. The sound stopped when gas pedal was released.
Upgraded later to WS80 and was not disappointed.

Given 82% while driving a Mercedes Benz C220 CDI Blue Eff. auto (225/45 R17 T) on mostly town for 9,375 spirited miles
It is a decently quiet tire with a very good dry grip, but I found that the grip was a little bit lacking in the wet. Since it is a winter tire, I must say that it didn't quite deliver in the snow: the handling was mostly fine, but take-offs were hard. My car is rear WD so it might be that you get a better performance with a heavier front WD car, not to mention 4WD car.
The wear rate is very good, even though the rubber mixture seems to be extremely soft at touch.

Given 81% while driving a BMW 330CI M Sport (225/45 R17 T) on mostly town for 12,000 spirited miles
Very good winter tyre. Used it for 3 winters. When it's slushy, snowy or icy the grip is fenomenal. I had lots of situations when there was so much snow that it seams that the car will stuck on the bottom, but it didn't. Never.
However, on the wet and dry conditions it is not the best tyre. They are made from soft rubber and it feels so, especially when you drive in highways on dry conditions. The car seems to be not stable when you hit more than 80 mph.
Would recommend it for nordic climate. Changing them to Dunlop Winter Sport 5 as I decided to use R18 wheels instead of R17.

Given 93% while driving a Ford fusion (205/60 R16) on a combination of roads for 5,000 spirited miles
I recently bought a set of 4 to put on my 2010 Ford Fusion Sport AWD. I have had many types of winter tires on my previous vehicles and so far about 5000km in Edmonton AB. in harse conditions from -30 icy conditions to snow covered ice and black ice, slushy, wet and dry, all I can say is WOW. These tires are great, stoping cornering and handling is superb. They are the quietest winter tire I have ever owned. Can't say to much for wear yet as I only have 5000km on them, but so far so good.
