New tyre markings bare goingg to be introduced at this weekend's Malaysian Grand Prix.

Now 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.
