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.

I had used it before purchasing the Champiro BXT pro. BXT pro is really good 140km/h not much shaking Champiro Eco good as well as I could not hear the tyre sound due to my exhaust.

For the price nothing compares to it as long as you keep your driving on the civil side, on the wet going at double the speed limit will bring you some handling issues. They last forever and are extremely comfortable at any speeds while giving a reasonable feedback.

Not bad for an Indonesian made tire. Works well in wet and dry road condition. Only that when driving around 140km/hr, it gets a little noisy.
