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.

Grip on dry surface is excellent considering the price, on the wet pretty good also. I'm very satisfied with the comfort and noise, which are more than acceptable for this price range. I had a very hard braking and I can say that these tyres saved me from being involved in an accident and that's the reason number one why I would gladly buy them again. Since I've covered some 5k km with them, I couldn't say much about wear, but so far so good. These tyres are not for those drivers who prefer aggressive driving style and want to have perfect feedback and handling.

Cheap tyres, very good in dry roads, just good in wet. Its not sport tyres,if you drive normal its ok. Noice is a little bad. I think its much better thar summer tyre Riken Road. This tyre made by another company not only Riken. Kormoran, Tigar, Orium, make the same tyre but the head for all is mother Michelin. Iam sorry for my language.

I wanted to test all season tires personally because many people I asked about them have conflicting opinions, and they all have different priorities, so I realised that I have to try them myself and see for myself what they are like. I had two solutions in front of me, one is to buy the most expensive tires on the market and see how it will suit me, and the other is to buy the cheapest and potentially the worst, so that I can see how bad it can get. So I ended up with these tires and realised that what I was most afraid of was not a problem at all, and that is traction on dry, wet, snow and when it is warm. These tires grip reasonably well, and in that sense there are no problems with them. What I found out later, and what no one talked about, is the subjective feel when driving with this tire, and this is frightening because the tire is very soft and the tread pattern is such that they squirm a lot. I thought this would improve after a while, which did happen to a lesser extent as they got a little better after a thousand miles, but they are still very squirmy and the car has lost its handling character, poise and precision. As it is Alfa Giulietta that has firmer suspension setup this is very pronounced, therefore I would not recommend these tires for a car of this type and character, but for more civil cars with softer suspension like a Golf, Megan, 308, and smaller city cars, this tire is very adequate and provides excellent value for money. For moderate winters when there is not much snow these are very good tires, but they are not sporty at all and do not provide a sporty feeling nor steering precision although they have adequate lateral and longitudinal grip.
