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.

Top 3 Silverstone Estiva X5 Reviews

Given 54% while driving a Mazda BT 50 (265/65 R17) on mostly motorways for 10,000 spirited miles
Very good in the dry but absolutely horrible in the wet. I drive on tarmac 99% of the time and these tires will break traction in the wet cornering at 40km/h. They also feel very fidgety in the wet and don't inspire confidence at all. Unless u don't mind driving really carefully and slow when the roads are wet I wouldn't recommend these.

Isuzu (225/45 R17 H) on mostly country roads for 900 spirited miles
This tires struggles to find grip around 85 km negotiating a bend. In the dry. You will feel a little skip before it finds its composure. Takes a little getting used to them.
Absolutely horrendous in the wet. If you drive in a wet climate. Please forget about these tires.
Braking response is the only thing that's okay on these. I'm already looking forward to changing them to the previous brand I used. Only about 10 quids more from these and they felt 10x better.

Given 61% while driving a Hyundai Santa Fe (235/65 R17 H) on a combination of roads for 40,000 average miles
Handles well but very poor wear.
