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.

Top 3 Yokohama Aspec A349 BluEarth Reviews

Given 60% while driving a Mazda 8 (MPV) 2.3 (215/65 R16 H) on mostly town for 28,000 average miles
Fitted by the factory on our 2014 Mazda 8 2.3. Had to replace after 45000km due to low profile (about 2.5mm left all around).
Quiet, comfortable tyre with a good wear for our heavy MPV. Good handling in the dry, but poor performance in the wet. I never experienced aquaplaning, but starting on a red light or uphill on wet roads set the tyres spinning easily. Also breaking at low speeds in parking decks or cornering over a manhole sent the car slipping easily.

Given 46% while driving a Volkswagen Golf (205/55 R16) on a combination of roads for 1,500 spirited miles
Rubbish cornering ability, compared to Michelin Premacy 3. Not dare trying in wet condition.
Quite confortable and quiet.

Latest Yokohama Aspec A349 BluEarth Reviews

Given 81% while driving a Mazda 3 Series (195/65 R15 H) on mostly country roads for 50,000 easy going miles
Fitted as standard to my Mazda3. Fronts lasted 38,000 miles and rears lasted 50,000 miles.A quiet tyre, with good handling characteristics. slightly more expensive than the competition, but all in all a good tyre as I would expect from Yokohama.

Given 77% while driving a Honda Odyssey (215/55 R17 V) on mostly town for 45,000 average miles
I drove my Yokohama Aspecs past the 52,000km mark in my Japanese/Asia Market Odyssey. They perform well in the dry and in lateral grip, with immediate response which I would attribute to a strong sidewall or good compound. The tread pattern itself is unremarkable and probably not the best for drag racing: it easily spins during wet redlight acceleration even back when it was only 20k. As OEM tyres they are very good, but I changed to Bridegestone RE002 now because the Yokies are too expensive.

Check out how the BEST all seasons tyres perform against premium summer and winter tyres!
Given 77% while driving a Honda Jazz (225/45 R17) on mostly town for 26,000 easy going miles
Fitted as OE, 26k miles fronts are at 3mm, rears 5mm so quite good wear rate. A good tyre for an undemanding car/driver, not the cheapest but a solid choice all round.
