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.

Given 95% while driving a BMW 525D (235/55 R17) on a combination of roads for 650 spirited miles
Surprisingly good tire. I sold the BMW 525d and because of that I dared to buy a Chinese tire on it. I went 1000 miles with it, but surprisingly good tires. The bad roads were smoothed out and the control was very direct. It would have been nice if I didn’t buy Continental at the time, but ones like that. I recommend the upper middle category.

Given 80% while driving a Alfa Romeo 1.9 JTD M (235/40 R19 W) on mostly town for 500 spirited miles
I'm in the UK and owned these tyres for about a month and a half now. I haven't had to drive in any real serious wet roads as of yet. But dry conditions they seem to grip really well. I only have them on the front at the moment but have 2 ready and waiting to go on the back once they are needed. I honestly can't tell you about comfort as my cat has sports suspension and I feel every bump on any tyres lol. One thing I do love is how the lip of the tyre sticks out to protect the alloy wheel. In that rare instance where you curb the wheel. Something previous tyres I've owned have not done. It will make me happier to have all the alloys of my car refurbished now. (Previous owner damaged them) Tyre ratings Treadwear 320 Traction A Temperature A This seems to be a fantastically good priced tyre so far. But I will submit a new review in about 6 months with wet conditions all being well they last that long.
