Firestone has use coloured sidewals in IndyCars for yearsTyre maker Pirelli has announced more changes to the markings on its tyre compounds so fans can more readily tell the difference between the different compounds in use, with the Italian firm announcing that it will colour the entire sidewall of its ‘option’ compound tyres from the Turkish Grand Prix onwards.

Pirelli had initially opted to give each tyre compound a differently-coloured ‘P Zero’ logo on its tyre sidewalls, but these proved near-impossible to identify when the cars were travelling at speed.

The next step – from the Malaysian Grand Prix onwards – was the addition of a thin coloured line on the outer edge of the ‘option’ compound tyres, but these proved little better for fans and commentators.

So the tyre maker has again responded to the feedback it’s been given, and Pirelli’s motorsport boss Paul Hembery confirmed further changes.

“The colours will be full colours on the sidewall and it will look much more significant,” he is quoted as saying.

Red coloured tyre sidewalls (to note the softer-compound dry-weather tyres) have been in use in the IndyCar series for several years, which uses tyres from the Firestone group (pictured above).
