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.

Good winter tires, safe drive on snowy roads, ofroad and mud. Od dry roads handling not quite so good.

Fiat (195/50 R15 H) on a combination of roads for 10,000 average miles
Missus Had them on a fiat 500 for 2 dutch winter's (we get basically everything, some snow, icing, flurries and lots and lots of rain). These tires fared well in all wintery conditions.
I found wet grip not as good as Michelin Alpin 5 or Conti TS860, but then again these are 60% of the price. Way better than awful Vredestein that I have on my own car. Recommended for a small light car without much power such as our little 500.

Given 87% while driving a Peugeot 607 (225/55 R16) on mostly country roads for 20,000 average miles
We drive the car in the Baltic states, where we get cold winters sometimes with lots of snow and ice. Dry grip is ok. Wet grip is very good and tires are excellent on snow. They also have enough grip on ice. So you feel safe. Tire wear is above average. But it is not an expensive tire. Comfort is good. I would recommend this tire and would definetally buy them again.

Initial Impressions Review
Given 70% while driving a Toyota Prius (195/55 R16) on for 12,500 miles
My used car came with these tires, I used them for 2 winter seasons, not sure how much it was used before but they lasted well during this time. I replaced them with the newer Uniroyal Winterexpert due to aging. This tire is rather noisy, anywhere above 50 kmh tire noise is constant. I was very satisfied with dry and wet performance, you can rely on it in snow conditions as well, but on ice it was very slippery, gave me almost zero confidence. Fuel economy was okay, as this is a lower rolling resistance tire. Unfortunately it is no longer available in my country.
February 10, 2026
Saab Automobile (245/45 R18) on a combination of roads for 5 average miles
Every week I drive about 300 km in central Europe, mostly on highways, but also local roads up and down the hills and a flat city streets.

Those Uniroyals represented a good choice, being well balanced between quality/price and very important wet and thin snow grip that MS + 77 is performing great and above expectations.
For Saab 9-5 NG it is recommended to pump them 2,6 bar, however I find 2,8 bar is an optimum for this tire/car combination.

Dry grip and dry breaking is somewhat different from summer tires, but not disturbing or alarming even on a warmer asphalt. Once I had to break harder in a situataion (140 km/h down to 60 km/h) on the warm road and that went without an effort and no need for ABS to kick in. On a very wet road it goes through water smooth and there is not a single occurance or an indication of aquaplanning.
Driving in a wintery city conditions where sometimes the temperature goes well below 0 and roads are icy and wet feels safe and a well adopted tire to such mixed conditions.
It also takes no effort to roll over fresh, thick and wet early morning snow covered streets and driving feels solid without slipping. That said, it also depends on a car's electronic antislip system.

Wear is, to my driving style, a tire's big surface, car's a weight and power (190+ HP) very reasonable, if not below expected.

Car behaves in winter conditions speeds on a highway almost as good my summer tires set of Dunlop Sport Maxx RT 2 in a summer. Car appears very stable and quiet at speeds of 130 -160 km/h while up to 160 - 200 km/h one can feel deeper grooves and road noise gets higher, so for short bursts over 160 km/h it is ok, but not too sustainable.
I can see that in a with summer tires, car consumes an average 7,2 l/100 km while in a winter consumption goes up to 7.6 l/100 km, but a part of that can be contributed to the other factors (cold air, compacted snow, ice, water, wind).

I would warmly recommend them to those who do not want to spend 35% more for the very premium brand, without very clear benefit. For the past 5 winter seasons my set was Dunlop SP WinterSport 4D and there is no noticable difference, except in price.

I hope that MS+ 77 will last as long and be reliable as it was so far.

Given 96% while driving a Volvo S60 D5 (185) (225/45 R17) on a combination of roads for 30,000 spirited miles
Only had these tires on the car two weeks, so cant really comment on wear other than we the Plus 66 on my wifes car and then are. The wet grip is unbealievable, driving on a motorway last weekend in driving rain and standing water, normally standing water "drags" the wheel none of that with the Plus 77 cut through it like a hot knife through butter. Very safe tire.

Given 81% while driving a BMW 520i (205/65 R15) on a combination of roads for 3,000 average miles
Got a set of these in a hurry in December to go on winter road trip in my BMW. The effects of the switch from a set of Dunlop sport summer tires was obvious.

Softer side walls dull the steering response. Road noise is high but typical for a mid range tire. The fuel consumption increased by about 3MPG. However dry grip available is amazing. Deep treads and its pattern deal very well with puddles.

The investment really starts to pay off when things starts to get icy. At the time of writing, this set of tires saved me from 5 ditches and 2 walls and many more other cars & pedestrians.

The first time I noticed these tires paying for itself was when I navigated in to a lay by in a freezing morning a little too fast. It was sheet ice and there was a HGV parked up ahead of me. I stamped on the brakes and these tires managed to muster enough grip to get the ABS going and stop the car. I foolishly decided to get out and check, only slip & to land on my arse. If it were not for these tires I would be under that HGV.

I can seriously recommend getting decent winter tires like this for any car. These save lives, property and hours of wasted time.

Rear wheel drive cars can be dicy during winter but now I'm more concerned about other cars with inappropriate tires crashing in to me.

If you are going to keep the current car for another few years, just buy a set of these. Most UK tire sellers now offer the "Tire Hotel" facility to store the other set of tires.

Given 81% while driving a Peugeot 106 (195/50 R15) on mostly country roads for 4,000 spirited miles
First time on winter tires this year, cold and wet but no snow or ice to really test these, however, they are almost like driving on a warm dry road! The wet grip is fantastic, even when it's 2 degrees outside. Very glad to have swapped for these in the winter and I am now a winter tire convert.
I've only done a few thousand miles so difficult to assess wear rate but I see a lot of tires in my job and they're not wearing unusually fast or unevenly.

Best tire for British conditions I've found.

Much better that my GoodYear Ultragrips 8s which could do snow but were poor on British cold roads (dry and wet).
