The Tire Reviews Score is the most comprehensive tire 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 tire 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.

Given 67% while driving a Honda HRV (225/50 R17) on track for 90,000 easy going miles
This tires is quite amazing. I driving for phv. Wet and dry, i still feel quite good as i not a heavy footer. Most important is, it lasts me 1 years 1 mth. Total mileages, more than 90000km. But poor is, it is super noisy. For the price, i paid. It is definitely worth it.

Given 79% while driving a Volvo 2.0 T5 Saloon (245/35 R19 W) on a combination of roads for 10,000 average miles
Generally meant to be a performance tire, has delivered good dry and wet grip thus far, wear rate is also rather good based on current 10000km usage. Good value for money tires
