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 Kumho WinterCraft WS71 Reviews

Given 52% while driving a BMW 335d (225/45 R19) on mostly town for 6,000 average miles
These have been on for 2 winters, swapping them out with summer tyre's each year.

The driving has been family car usage, on a mixture of motorway and town and country roads.

You knew when using them that they were designed for winter usage, functional with limitations of that design.

The reason I wanted to input the review for them was down the fact that they have only lasted 2 seasons, they have 5.3 mm tread left on the lowest level, however the side walls on 3 of them have cracked or split in several places which I did not expect to occur on a tyre that has just reached 3 years old. If you have these tyres please give them a regular once over.

Given 88% while driving a Toyota Sienna (235/55 R18) on mostly motorways for 37,000 average miles
I had these tyres fitted to my 3rd gen Toyota Sienna AWD and have been driving with the same vehicle for the past four years, all up I would've had these tyres on for a good 30000kms over that period and switched between summer and winter tyres every 6 months. For summer I ran Goodyear EfficientGrip SUV HP01.

These tyres gave me the confidence to take on slush when wet and cold dry. Where I lived was typically dry during winter but could get cold (I've seen down to -21 celsius) with some good snow days. My driving was typically long sweeping roads and highways with some dodgy farm roads thrown into the mix - these tyres took it all in their stride.

I was able to drive through the last cold season on the original set. Suffered a few punctures but that's more due to unavoidable road debris (nails etc.) than the tyres themselves. I've added that this is an end-of-life review as they were nearing replacement but it was also when I sold the vehicle (I gave the tyres to the next owner).

If I still lived in a country that would frequent sub-zero temperatures I wouldn't hesitate to buy these tyres again.

Given 84% while driving a Kia Motors Sorento III (UM) Diesel 2.2 CRDI (235/60 R18) on a combination of roads for 10,000 easy going miles
Excellent winter tyre, and not that expensive. In cold conditions, a confident feel, superb in snow and light off roading. Barely worn after 10000km, recommended for SUV's
