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.

The Michelin Primacy Tour A/S is an excellent tyre for three-season driving, offering a firm but composed ride and light, accurate steering. It truly excels in wet conditions, posting the shortest braking distances and feeling agile and responsive. This athletic character continues in the dry, with crisp steering, though the grip can fall off a bit abruptly at the limit. Its main drawback is its winter performance, where it struggles significantly in the snow compared to the competition.

Top 3 Michelin Primacy Tour AS Reviews

Given 63% while driving a Mercedes Benz GLE 450 (275/50 R20) on a combination of roads for 27,000 average miles
Noisy. These came on my Mercedes GLE450 and have been noisy since they had a couple of thousand miles on them. They have a resonant hum that only goes away on the smoothest roads. Wear is average for a heavy SUV. The rear tires will need replacement around 30,000 miles. The front tires have significantly more tread left. (Rotation of the tires is complicated due to different wheel offsets between front and back). Handling is OK, but not great. Lots of understeer with these tires. Ride comfort is good (I have the air suspension). Considering the Pirelli Scorpion Zeros all season as replacements.

Given 57% while driving a Ford Explorer (255/55 R20) on a combination of roads for 0 average miles
Just 10 000km, comfortable and predictable tires. You can easily feel what they are doing. But overall they causes to much understeering, on dry surface it starts squeek in corners surprisingly soon, but it squeeks much sooner than it slips, braking is average/below average. On wet surface it´s another story, braking is apalling, but cornering, it´s disaster. Try to corner in speeds in or below traffic flow? No, you gonna go just straight forward.

Well they have no homologation for winter use in Europe so after they will come of the car this fall, there is no possible comeback for them next spring.

Given 50% while driving a Toyota (245/65 R17) on mostly town for 28 average miles
Primacy Tour A/S on my 2009 Highlander had significant wear after 2 years and 28K miles. Tire rotation and alignment kept up, but not 100% so no credit toward new. Fine tires for th efirst year, but that kind of wear is unacceptable and do not recommend.

Initial Impressions Review
Given 50% while driving a Acura TLX A spec (255/40 R19) on a combination of roads for 5,500 spirited miles
OEM tires on my Acura TLX A Spec AWD and would not recommend, unless you don't drive in cold areas and don't like spirited driving. These are great for highway cruising as they are quiet and ride comfy. I am sure they would last a long time, but not planning on keeping them after this winter with dedicated winter tires.
I drove them once during a cold damp day when we had snow showers and could feel loss of traction at 35 mph on twisty roads. Was not driving spirited and could feel they would not be good in cold weather conditions with any dampness on the road.
