The Tire Reviews Score is the most comprehensive tire 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 tire 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.

Volvo V70 2.5 (205/55 R16) on a combination of roads for 8,000 average miles
I'm not a tire expert and I don't push a car to its limits so I don't feel qualified to score these tires but I will say this... I acquired these tires second hand last year on the advice of my garage; they had very little wear. I drove from London to Les Arcs, Val d'Isere and Celerina and back and there was a lot of snow on the roads and I felt the Cooper Weathermaster Snows handled admirably. This year, I drove to Lech with them. 6 feet of snow but the roads had been cleared. All good until the final 400 metres of unusually steep road... I couldn't get my car up there! All manner of other cars (without chains) made it up and down daily, My local hotelier (who'd lived on that road all his life) couldn't, either. We even tried reversing up (to have more weight on the driving tires). In the end, I had to put chains on. “Not good tires,” was his verdict. Mine is: they're fine if driven in towns and motorways and not aggressively on ordinary (ie not very steep) mountain roads.

Given 56% while driving a Honda Accord Tourer Type S (235/45 R17 H) on a combination of roads for 10,000 spirited miles
The tires feel good, grip well and so on. Drive good on snow as well.

I was shocked to find at the end of the season(single) that wheels started to vibrate. I drove to a garage to balance the wheels and there another surprise - all four tires had an uneven wear, every second knot on the outside edge of the Tire was shorter by at least 3mm. I have never seen this before in my life. Surely it is not due to the alignment of the wheels as tires before wear well (summer) and already did another 20k km on other tires that wear well.

I drive most of my distance on a wet and dry highway at 140km/h (around 85mph) in Switzerland, with temperatures mostly between 0-10 Celsius. I never drove in warm days, nor over aggressive style. Had plenty of occasions to try the tyrÄ—s in the mountain roads (lots of snow and ice, Inc driving with chains).

Given 94% while driving a Audi A4 Avante 2.0ltr tdi (225/45 R17 H) on a combination of roads for 10,000 average miles
Superb Tire,
During the snows of Decemeber drove everywear. BMW, Mercs stuck on hills, drove straight past. Felt good, control good could not fault them.
At the beginning ofthe month drove to Switzerland.
130 Kph on French roads, great. Did Calais to Zurich, 1 day.
Stayed in mountains. 18 inches of snow. Car drove through drift 12 inches deep to get out. Down snow covered hill with care but undercontrol.
Before his these tires. car couldn't go up even a small hill.

Great go anywhere winter tire. I only put 2 on the driving wheels last year and found them to be very efffective, long lasting and particularly good in the snow.

Put these on my V70 last winter (2010), had zero problems in the snow during November through to January excellent traction on soft and packed snow, felt okay on wet roads as well. wearing well, might just get another winter out of them as its not been too bad this year (2011-2012) I do about 20k a year and put PS3's on for summer
