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.

THREAD CHIPPING OFF, VERY BAD TYRE

Given 99% while driving a BMW 318 coupe (205/60 R16) on a combination of roads for 47,000 spirited miles
I was not keen on these tyres as I wanted a sports tyre due to my um spirited driving style. However, these have been a brilliant match to the car. they have exceeded nearly every expectation I had for them. In fact, even at this distance of driving them they still have about a third of the tread left unfortunately one of the side walls on the rear was cut with some debris on the road so new tyres are a must. Unfortunately, money is a bit tight and I may not be able to stretch to these again.

Dry grip and wet grip are both OK. These tyres feel safe and comfortable when driving around the city or on motorways, but the handling is so-so (but manageable) on twisty B-roads and there is a lot of tyre squeal when cornering, even at very low speeds in multi-storey car parks.. So far they've lasted 35,000km and I expect to get another 10,000-15,000km. Overall, these are a fine general purpose tyre ... unless you enjoy driving with gusto when the opportunity arise. But if you're a sedate driver, the EP100s are more than fit for purpose.

Given 42% while driving a Hyundai elantra (195/65 R15) on mostly country roads for 200 average miles
compared to the cars original tyres i have found them to be hard and uncomfortable to drive on. car is feeling bumps a lot more and suspension banging a lot more.extremley disappointed in bridgestone thinking of changing to another brand.would not recommend.

Given 77% while driving a Toyota Camry (225/45 R17) on mostly town for 45,000 easy going miles
Adequate grip, comfort and noise. These affordable tyres benefit from low rolling resistance.

The only negative is that the walls are a bit softer than what I would like. Whilst this is not a deal breaker for me, I can see more aggressive drivers being put off by this wallowing feeling.

Given 59% while driving a Toyota Camry (225/45 R17) on mostly town for 150 average miles
Just got my Camry with 215/60/R16 ECOPIA and run in for about 80km. Obedient in corners but undecided on straights. Comfort is better than XVM1 but I can still hear that anoying rolling noises. Tested up to 180kph.

Given 76% while driving a Ford Fairlane NL (205/60 R15) on a combination of roads for 500 easy going miles
Firstly have not had the tyres long enough to evaluate wet performance or wear factors so have chosen 50 / 50.
They are very quiet and roll nicely actually needing to apply brakes more often as opposed to the Toyo's I had on previously. I also went dowm in width from 215 to 205.
I dont drive radically so cannot comment on squeal etc but then again a high performance tyre I was not after. So far pleased with my purchase and at $109.00 a corner with $30.00 for Nitro from Bob Jane feel it great value for a quality tyre Made In Japan over a cheap no name brand.
Hope this helps.

Given 43% while driving a Nissan Maxima Ti (215/55 R17 V) on mostly motorways for 5,500 average miles
These tyres are OK in a straight line ie, on the motorway, but try to corner at anything above pedestrian speeds and they squirm, squeal and protest. The handling ability of the Ecopia is quite simply appalling. They feel like they're going to roll off the rim.

Dry grip is pretty good, and they make for a nice smooth ride, but I'm going to switch these for Michelin Pilot Exaltos.
