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.

Latest Tyre Test Results
The Radar Dimax Ice has lower ice grip than the other friction tyres in the test, but it is quiet and maintains good rear-end stability even when steering slowly in extreme situations. The tyre's behavior on snow is logical, though the front tyres tend to lose grip easily at the limit. On asphalt, its grip level is insufficient for both wet and dry conditions, resulting in long braking distances and difficulty with evasive maneuvers due to the front tyres losing grip, though the rear remains stable.
7th/8
The Radar Dimax Ice performed poorly overall, though showed reasonable ice grip thanks to its soft compound. However, it failed in most other areas with extended braking distances on both wet and dry surfaces, early aquaplaning, high noise levels, and unpredictable handling under pressure. Despite its low price point, its limited capabilities make it poor value.
