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 Giti GitiWinterW1 Reviews

Given 75% while driving a BMW 330i (235/45 R18 V) on mostly motorways for 7,000 spirited miles
I have a new set of W1 on my car, first winter, driven mostly on wet road and one vacation in France. The tyres are very nice and quiet on dry roads. On wet they lacking some grip especially at high speed. Mileage is difficult to judge. the car has 9.000 km (of which 7,000 with winter tyres) and they are still like new. During ski holidays in france had the chance to try them in actual snow and they were fenomenal. high grip, even on very slippery hills, confident turns and fast decelerations. Had real pleasure dring the car!

Given 89% while driving a Audi A5 (225/45 R17) on mostly motorways for 20,000 average miles
Initially hesitant seing the “ made in chin”, but decided to try it as it was engineered in europe (germany), and the good price.
Excellent on wet road. Only very basic test on snow ( but seemed very grippy). Quiet and stable at high speed.
A very nice surprise.
