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 53% while driving a Rover 75 auto (225/45 R17) on mostly town for 9,000 average miles
My car came fitted with a brand new set - I expected to have to change them quite soon but 2 years plus on they seem quite reasonable - I have done approx 9000 miles on them. I do find them quite a noisy tire though

Given 74% while driving a Saab Automobile 2.0T (210bhp) (225/45 R17) on a combination of roads for 100 average miles
Only had the two fronts replaced with these a week ago but did notice an immediate improvement on comfort and handling than the two Avons that came off (down to the legal limit). So far really happy with them, haven't had the chance to test in wet yet but don't drive overly spirited so will adjust driving style to suit as need be. Excellent price and happy so far. What more can you expect from a budget?
