2018 Auto Express All Season Tyre Test

How your ranking is calculated

Each discipline is scored against the best non-reference tyre 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.

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.
