Pirelli have revealed they will run new markings on their slick tyre range in pre-season testing so that fans can tell the compounds apart.
This year, although Pirelli will still have five different compounds for their slick tyres, they will be using only three colours: white, yellow and red.
But while that may work at grands prix when only three compounds are in play, for testing all five will be available.
As such Pirelli have announced that their hardest and softest compounds won’t carry stripes on the sidewalls.
That means the white with no stripes will be the hardest compound and the red with no stripes will be the softest.
Mario Isola, head of F1 and car racing, explained: “Normally we will only see three colours at every race, so we’re only using three colours at the tests as well. But we want to make sure that people can tell the compounds apart.
“As a result, the very hardest and softest tyres won’t be marked with stripes: only the colours will vary. This will be the case for the in-season tests as well.”
Pirelli will remain Formula 1’s tyre supplier for the next four years have re-signed with FOM last season.
