SINGAPORE -- Under normal circumstances the Singapore Grand Prix would be a one-stop race, but there should be opportunities to use tyre strategy to make up positions.
The performance of the soft tyre is good for about 10 laps, but will drop off rapidly once degradation takes hold. That means drivers willing to make a pit stop before their rivals could benefit from the extra performance of a fresh set of mediums, rather than ageing softs. This is known as the undercut and any driver with a gap behind him is likely to try this strategy to come out on fresh tyres and in fresh air to try and make up the difference.
