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.

Latest Tyre Test Results
Stable running and short braking distances on snow, low rolling resistance
Very limited capability with low aquaplaning resistance, long braking distances on dry and wet roads and inharmonious understeering handling
Good snow performance
Perhaps the perfect example of why budget winter tyres struggle in the UK climate. While this tyre was excellent in the snow it was rated dangerous in the wet with massive braking distances and terrible aquaplaning properties. Overall Autobild called the tyre "defective"!

Given 20% while driving a Dacia duster 4x2 2011 (225/45 R17) on for 0 miles
Tires already fitted to the car, no grip on wet roads, and worse on wet roads. strongly discouraged

Mercedes Benz (195/65 R15) on mostly country roads for 31,000 easy going miles
Dangerous tyre, no feedback in the rain. Bought these tyres as good as new, but never satisfied regarding grip or feedback. In rainy wether absolute dangerous to drive with. At end of life replaced by Vredestein Snowtrack 3. An absolute good choice in what a tyre has to be.

Given 54% while driving a BMW 135i (225/45 R17) on a combination of roads for 2,000 average miles
These came with the car I bought and have used these tyres for 4 winters as my spare set of winter wheels, but only if absolutely necessary. The few times we've had snow on the roads, they've been great and had no traction issues driving in the snow in my RWD BMW. But when the roads are snow free and the roads being wet and salted, these tyres are what can be described as dangerous!! In cold wet conditions I have to drive at a snails pace, the lack of grip is shocking if you're not careful, will find your car either understeering into the nearest kerb or oversteering into the nearest ditch. Stopping distances is also dreadful and your ABS will be working overtime. Can be good fun in an empty carpark if you want to practice drifing at low speeds, but I would advise to steer clear of these tyres for normal road use and only use them if absolutely necessary like when snow has actually settled on the roads. Do not use in cold wet greasy conditions. In fact, just don't buy them and spend a little more on decent winter rubber.

Given 76% while driving a Skoda octavia estate 4x4 (225/45 R17) on mostly country roads for 0 average miles
Lets be fair. These tyres are designed for wintery icy conditions. So if you want them for all seasons buy an all season tyre. These tyres feel no different in the dry or cornering to the summer tyres I replaced. I drive a Skoda Scout 4X4 ( normally ) as in sticking to the speed limits Etc. Not throwing it into the corners and hoping for the best. Yes they are speed rated a V = 149mph so should stay quite cool and not over heat , for everyday driving. To say how much grip they have, these are nice and quiet. How long they last is up to the weather. If it stays dry then they will wear quickly. So hoping for a little snow this winter.

Given 79% while driving a Peugeot 508SW HDi estate with 17" wheels (225/45 R17) on a combination of roads for 0 average miles
If you're a sensible driver, can read road conditions, anticipate well, these winter tyres will give many many safe miles of driving in all weathers. I'm a taxi driver covering over 1,000 miles week, and believe me winter tyres are the best investment any road user could make. Whilst other drivers are often idiots, too fast, too close, wrong gear on snowy roads etc, these tyres will get anyone home, safely, up hill, down hill, snow, sleet, ice, the lot. - for the record, winter tyres work and aid safety in low temperatures, they are NOT just for snow covered roads. They grip, clamp, glue and bond themselves to the road, believe me, like I said I drive 50k year in all weathers. These budget tyres are worth the money, just be steady and keep in a low gear!

Given 73% while driving a Volvo S60 D5 (185) (225/45 R17) on a combination of roads for 1,000 average miles
Even though Volvos have a 'Winter' function for their autoboxes (it starts in third gear to give more progressive torque), it was unusable in the snow of the last UK winter on the fitted Conti 6000's. Even the slightest slope in medium snowfall defeated it. I needed to get mobile quickly, and my local supplier suggested Rockstones at about £60 a corner.
Against advice, I only fitted two to the driving wheels, and they were a revelation. Worked well on all surfaces including hardpacked ice, and performed really well once the bad weather had gone. So well that I forgot they were on until I took my car in for a service in May!
Not noisy, good feedback, and gets you about once the white stuff comes down. Even though I had massive doubts when I fitted them, I'm going back in October for two more to fit them all round.
Hope this helps!
