Formula One tyre manufacturers Pirelli recently announced that they would be looking into making each of their compounds with a 0.4mm thinner thread for the races in Spain, France and Britain.

The decision was taken by the hierarchy to avoid blistering while some considered the move was to assist the reigning champions Mercedes, after they complained of experiencing issues during pre-season testing.

During the three mentioned races, the matter of favouritism was raised from several quarters having seen Lewis Hamilton grab pole position for all the three races and winning two of them.

However, Pirelli’s F1 chief Mario Isola insisted that their modified tyres were introduced after not only Mercedes, but, when all the teams reverted back to them with the same problems during their respective pre-season, which prompted them to make the move.

Both of Barcelona and Silverstone tracks were resurfaced over the winter period, meaning those circuits would now generate a lot of grip, putting a lot of energy through the tyres.

It would not wear out the tyres physically, rather drive surface temperature up, causing blistering and the French GP circuit’s high-speed track would also leave it, concerning the same problem.

Ferrari ace Sebastian Vettel tested the normal Pirelli tyres during the post-Spanish GP in May and asserted the Italian outfit would have been worse off in the race without the modified rubber.

Speaking on the issue, Isola said: “I’m sure we were not far from blistering at Silverstone. With standard tread we probably had blistering.

“With this reduced gauge, it was possible to have a real race, looking at the real performance of the car, without any external effect that was changing the balance.”

It remains to be seen if the alterations not only provide better performances for each team, but, more importantly, satisfies every outfit and dismiss the 'silly' conspiracy theory that has been doing the rounds for quite a while, which, in reality, never was in existence.
