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 56% while driving a Honda Civic 1.8 (205/55 R16) on a combination of roads for 3,000 easy going miles
The design of the tire is good. But the handling is so terrible! My car is all over the road and there's nothing I can do to prevent it. The side walls are way too soft.

Given 43% while driving a Kia Motors Forte Koup (205/55 R16) on a combination of roads for 5,000 easy going miles
Canadian roads. I'm a very gentle driver, and don't slam on brakes/ throttle inputs. These are Absolutely horrendous on snow handling/ acceleration and braking. Barely capable of coming to a clean stop at creeping speeds. Constantly having to throttle up to fight against the car. You get unpredictable Understeer to oversteer, massive amounts of steering lock required to turn and good luck getting out of a 30cm snow bank. If you have harsh winters, stay as far away from these as possible. They get very scary on highways with snow tracks forming. It "aquaplanes" on snow and slush quite easily. It feels extremely unsafe. The only thing surprising about the tire is the fact that it has more grip on ice than It does on light snow.....

Given 73% while driving a SEAT Leon Cupra Tdi (225/45 R17) on mostly country roads for 5,000 spirited miles
While this may be a combination of me being fussy and a characteristic of the softer compound, they feel a little bit spongy when going over speed blobs (the narrow blob-style speed humps) if you hit them off-centre, and pot holes on corners. Otherwise, they have exceeded my expectations of a cheap tyre. I had them on from around the start of December last year until about May/June this year when I got round to taking them off and the wear rate is much less than I expected, considering the condition of the roads I use.

Given 53% while driving a BMW 335d (225/45 R17) on a combination of roads for 4,000 spirited miles
We'll I've just put these back on for winter 2 with very little wear from last winter. However they seem a lot less capable now especially in fast cornering. I think I will mess around with tyre pressures and see if this sorts it out, but for now take the first review alongside this one.

Given 69% while driving a BMW 335D (225/45 R17 W) on mostly country roads for 20,000 spirited miles
Put these on my 335D just as a taster to see if winter tyres worked last Jan. and oh my goodness they transformed the winter capabilities completely. With summer tyres on the car would hardly drive off the flat drive never mind up a snowy slope- with these it is better than the neighbours Audi quatro and just does not get stuck. As far as road manners are concerned- feels far safer than the summer tyres, reduces tram-lining, the only negative is wet traction under heavy acceleration- looses it a bit.
