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.

Whats the tread depth on the rotalla setula s330 winter tire?

Unfortunately we don't have tread depth data for the S330. One thing to note is that tread depth does not correlate with wear, especially for cheaper tires, where a higher starting tread depth can much easily wear out more quickly than a well engineered tire with a lower starting tread depth.

Given 84% while driving a Mazda Cx90 (275/45 R21) on a combination of roads for 0 miles
Pretty good tire, does what it needs to do. They're soft, so I dont expect long tread life

Given 89% while driving a Audi A7 3.0TDi Auto (225/45 R17) on mostly country roads for 1,000 average miles
Modern winter tires have come on leaps and bounds. In the dry they don't feel any different to the Goodyear f1 it had previously, in the wet they feel safe and secure with very little if any understeer when pushing around wet roads. So February 2024 we had 150mm of snow here in Yorkshire and I didn't fail to get anywhere and I always drive to suit the conditions and we had no problems. The tire suits the big Audi A7 Quattro and it's a supremely comfortable and quiet tire.
