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.

Initial Impressions Review
Given 28% while driving a Skoda Octavia (205/55 R16) on for 10,000 miles
One of my worst experiences is with these winter tires. They have no grip in rain or snow, I just slide around, but we hardly slow down at all. Even in dry conditions, they are one of the worst winter tires I have ever used. I have them on my company car, I would never buy them for private use, and our company avoids this brand because of complaints from others. They are not much cheaper than tires from better-known tire manufacturers, and a few euros could save lives. Everyone who has driven and used them so far has complained about them!

Please, if your life is important to you, don't buy this tire. Its only advantage is that it's comfortable.
