Formula One tyre supplier Pirelli is considering using more non-consecutive tyre selections, after being pleased with their choice in China.
Sporting director at Pirelli, Mario Isola explained why they decided to skip the super-softs for the race in Shanghai.
"When we selected the tyres for China we had the information coming mainly from the Abu Dhabi test because it was in January," Isola said.
"Based on that number we saw that soft, super-soft and ultra-soft were very close. We had 0.3  and 0.4, something like that.
"So we said we can make a selection where we don’t choose one level and we jump. In that case, if they’re really close we should have a delta lap time between soft and ultra that is in the range of 0.7, that is the same range we saw with medium to soft, obviously with higher degradation."
Isola added that this is not always going to be the case and Pirelli are always learning, saying:
"If we look at what happened in Bahrain, soft and super-soft were not so close. This is part of the experience we are collecting. All these numbers we are collecting from races we put into our system to make even better selections for the next events. That could mean jumping one level or not."
