Paul Hembery expects the revised hard compound that will be used in Spain this weekend will give the teams a "wider working temperature window."
After several teams complained about the Pirelli tyres, which suffer from high degradation, the Italian manufacturer decided to make changes ahead of the Spanish GP - but just one.
The company has altered the compound used for their hard tyre, which is now more like the 2012 version.
As such Hembery expects the revised tyre will have a bigger working window although it won't be as quick as its predecessor.
"We're introducing a revised version of our hard tyre in Spain, which is closer in characteristics to the 2012 tyre," said the Pirelli motorsport boss.
"This new tyre gives us a wider working temperature window - although it delivers a little bit less in terms of pure performance - but it should allow the teams to envisage an even wider variety of race strategies than before in combination with the other compounds, which remain unchanged this year.
"This is a decision that we've come to having looked at the data from the first four races, with the aim of further improving the spectacle of Formula One.
"In fact this is almost a tradition with us now, as we also introduced a revised version of the hard tyre for the Spanish Grand Prix in 2011, which was our first year in the sport.
"We'd expect the medium tyre to still be significantly faster and this is the one that the teams are likely to qualify on, whereas the hard is likely to be the preferred race tyre."
Hembery also confirmed that the drivers will all have an extra set of tyres to run on Friday.
"As permitted by the current regulations, we'll be supplying an extra set of prototype hard compound tyres for free practice, which will hopefully ensure that all the cars run throughout these sessions.
"It's something we wanted to do to encourage all the teams to run as much as possible right from the start, especially with the rookie drivers, to give fans the spectacle they deserve to see."
