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.

Translation and Summary The APlus AS909 is rated as "deficient" overall for driving safety, a score dictated by its significant weaknesses on wet roads which led to a downgrade of its final grade. On dry roads, its performance is merely "adequate," offering poor and imprecise steering feedback that requires constant driver correction and early oversteering in dynamic maneuvers. On wet surfaces, the tyre reaches its limits, earning a "deficient" rating for its braking distance and handling due to very low grip, making it difficult to control. Its winter performance is deemed satisfactory overall, securing good scores for braking and traction but only an "adequate" rating for handling, as it struggles to combine forces effectively. In contrast, the Chinese-made tyre achieves a good environmental score thanks to very good projected mileage and low fuel consumption. However, its sustainability is rated as just adequate because the manufacturer failed to provide requested ISO certifications or other sustainability credentials, and its weight is high.
