Paul Hembery: "Essentially we went for softer compounds this time as in 2012 the Indian Grand Prix was just a one-stop race, and the combination we brought this year allows for a two to three stop strategy. After what we have seen today, wear and degradation is generally in line with our expectations but there have been some issues with blistering on the soft compound while some drivers ran up to 24 laps on the medium tyre.
"The medium seems set to be the optimal race tyre, while the soft tyre should be the one to qualify on, as it has been about 0.8s to a second per lap faster up to now. Assessing the drop-off in performance will be the key to formulating the strategy and the timing of the first pit stop. Consequently, some teams will also be evaluating the potential benefits of starting on the medium. However, the track hasn't finished evolving yet, so the final decisions won't be taken until after free practice tomorrow."
