A tweak to the tyre regulations comes into force this weekend, introduced remarkably quickly during the course of the season. The reg. change is to allow the use of a ?bonus? or ?emergency? option tyre of a softer specification.
Prior regulations allowed for eight front tyres of two compounds, and ten rears of two compounds. The new regs. give nine fronts of three compounds, but keep ten rears of two compounds, but the teams can decide the split of compounds within the ten (six of one, four of the other for example).
The rush to change the rules came about after discussions at Assen and the game of skittles that was the Friday Morning Free Practice session in Germany this year. The track temperature in both cases was too low for the compounds on offer, meaning the harder compounds never got up to temperature, and so the grip was not there.
Could the new option front be used as an old fashioned qualifier? As reported on Eurosport today, we are unlikely to see this at Brno, as the demanding front-end nature of the track means the soft tyre compound squashes too much under braking, reducing front end feel and actually resulting in a slower lap time.
Where we will see the ?emergency option? used is on cold morning practice sessions. I?m looking at you, Phillip Island.
