F1 introduces clearer tyre marks
Kimi Raikkonen's Ferrari on its way to victory in the Australian Grand Prix
In Australia, it was impossible to tell which tyre a car was using
New tyre markings will be introduced at this weekend's Malaysian Grand Prix to help spectators follow the race.

A rule change this season means that teams must use both of the two types of tyre supplied during a race.

The two types must be distinguishable but a first attempt failed because a small white spot painted on the tyre could not be seen when the car moved.

Following a re-think, the softer of the two types will now have a white line painted within one of the four grooves.

Bridgestone's head of track engineering operations, Kees van de Grint, said: "This has received a positive response from teams and onlookers.

"It is time consuming to apply to the tyres but is clearly visible on track."

Follow the Malaysian Grand Prix live on BBC Radio Five Live and this website - qualifying starts on Saturday at 0700 BST, with the race on Sunday at 0800 BST.
