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.

Top 3 Kleber HYDRAXER Reviews

Given 86% while driving a Honda Accord (225/45 R17 W) on mostly town for 25,000 average miles
Very good tire. After 3 years and ~30000 km tread looks very good, about 2/3 is left. It is little bit noisy, but has very good wet and dry grip.

Very good at reasonabe price.

Given 77% while driving a Audi A3 1.8T sport (205/55 R16 W) on mostly country roads for 25,000 average miles
Excellent wear for me (25,000 miles, still looking good) and excellent wet grip when new. Wet grip level decreases a lot with time, but dry is still very good.
