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.

Top 3 Toyo Snowprox S943 Reviews

Given 57% while driving a Toyota Celica VVTi 140 (195/60 R15) on a combination of roads for 2,500 spirited miles
In cold dry the tyre had decent grip and handling, however once it was warmer, more than 10-15 Celsius, it started to lose some grip, in extreme condition around 18-23 celsius which is summer tyre temperature I experienced its limit and my brake distance was also increasing. Rain and water was not a problem as long as you avoid driving directly into larger puddles. Road feedback is not very great, but it is subjective, I had the tyres in a very tough sport suspension so it was a completely empty feel but not uncomfortable, but its not a sporty tyre anyway. Wear seems good so far its not losing patterns very quickly, tho I only have them for 2 seasons. Snow and Ice experience is not exist. Comfort was OK but once it got a little warmer it become super loud, it wasn't a good experience. I would probably buy the tyre again, but not for this car, its decent for passenger cars but not so much for sporty cars.

Given 51% while driving a Daewoo Leganza (195/65 R15) on mostly motorways for 10,000 spirited miles
I wonder how some reviewers can mention that this tyre has good snow performance? It's absolutely rubbish. Last winter I got stuck twice in little layer of snow and that never happened before. For cold and wet weather it's fine and also nice handling. More stable than my Vredestein hitrac summer tyres. But forget about it in the snow. Maybe on a small vehicle it will work but don't use them on any midsize sedan. Ice? I still have nightmares... I bought now studded Toyo's and will review them coming winter.

Worst tire ever! DO NOT BUY!
I got paranoid everytime the roads were wet. 0 handling, 0 grip. Before these ones I had on Sava eskimo's that had about 40k km on them and I swear that those old sava's had better grip than these c**p Toyo tires.

Given 77% while driving a Peugeot 1.4 HDi (195/55 R16 T) on mostly country roads for 12,000 spirited miles
This was the tyres who were fitted on the car as i bought it. Were pretty good in the dry and wet and i would say good in snow and ice. they wore average as i've got a commited driving style, combined mostly with twisty country roads. They have hold on for 10K miles on front and 20k on rears (kept the rear in hot summer).
Rolling resistance is good for winter tyres (5,5l/100km or 42mpg)
Conclusion: good value for the price with stong points for wet handling
