Pirelli to ramp up tyre markings for Turkey

Pirelli will colour the entire sidewall of its ’option’ tyres in Turkey.

The move follows complaints that the original coloration of the ’Pirelli P Zero’ branding - and even the subsequent addition of thin lines on the outer tread - made it hard for spectators to visibly differentiate the compound types at the first three races of 2011.

Pirelli motor sport director Paul Hembery said the soft ’option’ compounds will be "far more visible" from Istanbul onwards.

"The colours will be full colours on the sidewall and it will look much more significant the amount of colour we put in so the black can’t get in the way when it’s spinning," he said.
