In F1 2016 the tyre consumption in final part of a race is too high respect the pratice session?

In practice session the tyres haven't a high tyre consumption while in final part of the race they have a high consumption...
For example in Melbourne I do around 1:29 in practice session while in race I do only 1:30 - 1:30,5 because the tyres have a high consumption...
How can I adjust my setup?
Will be it correct in F1 2017???
