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.

Given 93% while driving a Mazda 6 (205/55 R16) on a combination of roads for 65 average miles
I have been using Bridgestone Potenza giii for several years, in Mazda 6 the duration is optimal, very efficient in wet and dry braking.

Given 82% while driving a Suzuki swift sport (195/50 R16) on for 40,000 miles
fitted those tires since 2014 and I give those reports below after 40.000 miles usage: dry grip is outstanding. wet grip is good and handling was superb so really confident to drive up to 80mph on wet roads. road noise is acceptable; not as good as Dunlop LM705 which I use right now as the replacement for this tire. wear is okay... since I rarely use the car haha, but I would recommend if BS continue to produce this tire again, or at least a replacement with adequate specs like this Potenza G3. ciao

Given 90% while driving a Ford Fiesta (185/60 R14 H) on a combination of roads for 5,000 spirited miles
replaced michelin energy xm1+ with these. have run 5k till now. dry grip is great! no complaints!! the tires don't squeal even at the limit and have great feedback! wear is good. they are silent at motorway speeds. comfort is good but the tires are very sensitive to tire pressures! 30 psi is the sweet spot with these! overall excellent performance tires!

Given 84% while driving a Ford Fiesta ST (225/50 R16 V) on mostly motorways for 10,000 spirited miles
Used it in trackdays, dry and wet conditions. Feels like you're on railways.
it's very intuitive, when driving on it's limit, to tell when it's about to loose. making easy to adjust so to avoid it.

For a family trip is quite noisy.

Tried a lot of tires, but i'll stick with this one.

Very reliable, silent, comfortable, lasting. I got 225/50 R17 on Ford Fusion. I already drove over 40.000 km and it looks like to go very longer.
Ford Fusion Approved!
