Pirelli produce five specifications of dry-weather tyre, each with a distinguishing sidewall colour – ultrasoft (purple), supersoft (red), soft (yellow), medium (white), hard (orange).
At each race the teams have access to three specifications (or compounds) of these dry-weather tyres.
Each car’s full race weekend allocation consists of 13 sets of dry-weather tyres, four sets of intermediate tyres and three sets of wet tyres.
