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 Bridgestone Potenza S02A Reviews

Porsche 996 911 Carrera 2 (225/45 R17) on mostly country roads for 4,000 spirited miles
I can compare this tyre to PS2 and PSS on the same car but variations in widths and rim widths.

Maybe the S02A does not offer quite as much grip as the Michelin (I really can not tell the difference) by tests but I can tell that compared to both the Michelins the S02A gives better feedback. It is more linear and I would say it requires less slip angle to generate side force. However, the S02A are on 8.5 and 11 inch rims as the Michelins have been on an inch narrower rims.

I bopught these second hand but practically new. Of the three mentioned these are actually my favorites.

Given 76% while driving a Porsche BOXSTER 2.7 (255/40 R17 W) on a combination of roads for 30,000 average miles
Just about to renew all 4 tyres after 30 months & 30,000 miles. Driven daily in all weathers, I found they performed very well, dry grip & road holding I couldn't fault, wet grip & road holding couldn't fault either even now as I'm about to replace them & they at the limit of their wear. Good grip & road holding in the snow to, although they wear a little skittish in the last snow (march 2018) but not surprising given they are at end of their life. These tyres wear very well compared to the Pirelli PZero Rosso that were on before with18,000 miles driven on them before needing to replace them. Only fault these tyres have is in the cold weather when both comfort & grip suffer a little until they warm up but on really cold days they need to be driven
a little more cautiously. I drive steadily generally but do some spirited driving reasonably often as well. I would have no hesitation in reccomending these tyres to a fellow Boxster owner.

Given 71% while driving a Porsche 986 Boxster S (255/40 R17) on a combination of roads for 6,000 average miles
Bought a 986 Boxster S with these already fitted - took a note of current wear (7mm front & 2mm rear) and then used the car. 5mths and nearly 6k miles of normal use later, wear update - front 6mm & 1.8mm rear, so they're hard wearing. There's plenty of grip when tyres are up to temperature but they're rubbish cold.
