Movement is compared with the default calculation, not the published finishing order. Scores use unrounded totals for ranking.
No ranking for this setup. Give at least one category a positive weight and include a discipline in each active category, or reset the weights.
Filtering never changes the benchmark, scores or positions.

These are calculated scenarios, not new test awards. The published verdict may reflect judgement, close results and factors outside this calculation.
Not ranked: a measurement needed for these weights is missing. Missing results are not treated as zero or redistributed.
Reference tires provide context only. They do not set the benchmark and cannot win the personalised ranking.
Weighting vs real impact
What decides this ranking
The weighting is how much each category counts. The real impact is how much of the difference between the tires it creates: a discipline in which every tire performed about the same barely changes the order, however much it counts.
No weighting is recorded for this test, so the weighting here starts from Tire Reviews’ season defaults, not from the test’s own scoring.
- Dry Weighting 82.2% Real impact 67%
- Off road Weighting 1% Real impact 2%
- Comfort Weighting 16.8% Real impact 31%
- Subj. Noise counts for 8.4% of the score but creates 17% of the difference between the tires, because their results in it were far apart.
Every discipline 4
| Discipline | Weighting | Real impact |
|---|---|---|
| Subj. Dry Handling | 82.2% | 67% |
| Subj. Dirt Handling | 1% | 2% |
| Subj. Comfort | 8.4% | 14% |
| Subj. Noise | 8.4% | 17% |
How it is worked out: each discipline’s weighting is multiplied by the spread of its results (the gap across the middle half of the tires, as a percentage of the best result), then shared out so that all the disciplines add up to 100%. It estimates what separates the tires; it is not a second set of weights, and it follows the weights you set.
How your ranking is calculated
Each discipline is scored against the best non-reference tire in the full test field: best ÷ result × 100 when lower is better, or result ÷ best × 100 when higher is better. Discipline scores are rounded to two decimal places, then combined using your weights.
Within-category weights divide that category’s share of the overall score. A 50% wet category and 40% wet-braking share give wet braking 20% of the total. A weight is a scoring priority, not a measure of its actual effect on the ranking: the performance gaps matter too. What decides this ranking ↑
Published joint positions are preserved separately. Calculated positions tie only when their underlying scores match; two displayed scores can look equal after rounding.
A zero weight excludes that category or discipline. At least one active discipline is required, and the disciplines in every active category must have a positive total.
