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.

The CST Medallion Winter WCP1 receives satisfactory ratings on dry and wet roads but poor winter performance, resulting in poor overall driving safety despite satisfactory environmental performance for a poor overall judgment. On dry roads, it shows only adequate precision and steering feedback requiring frequent corrections, with significant oversteering tendencies and adequate limit behavior, but achieves satisfactory ratings overall thanks to above-average braking distances. On wet surfaces, it achieves satisfactory ratings with good braking and longitudinal aquaplaning but only satisfactory lateral aquaplaning and adequate handling due to weak grip, low limits, and inadequate force combination. In winter conditions, it receives poor ratings despite satisfactory snow braking and traction, with poor handling performance due to inadequate force combination resulting in very imprecise control and very low limits with early under/oversteering tendencies, plus only adequate ice braking. This Turkish-manufactured tyre receives satisfactory environmental ratings with good predicted mileage and tyre wear, but satisfactory efficiency due to high weight despite good fuel consumption impact.
