One of the most challenging areas of the circuit is the complex that makes up Turns 10 and 11: both of which are taken in quick succession almost as single corner. The tyres have to withstand a high-energy lateral force for around seven seconds. The front-left tyre is worked hardest here, and it has to withstand an acceleration force of up to 4g on the exit of the corner, where maximum grip is needed to hold the racing line.Turn 4 is another crucial area of the circuit. Here, the cars decelerate from 320kph to 90kph in just 140 metres. The tyres are subjected to a deceleration force of 3.6g, but still have to guarantee stability and precision throughout the braking area.India also has one...
