May 20 (GMM) Pirelli on Monday essentially confirmed reports the F1 supplier will now make only minimal changes to its tyres for Canada next month and beyond.
After the waves of controversy and criticism following the Spanish Grand Prix, the Italian marque announced it would be making structural and compound changes for Montreal that should reduce the number of pitstops per race.
So Pirelli on Monday is backtracking, with motor sport boss Paul Hembery telling Reuters F1's official supplier only wants to make changes "with minimal disturbance to the sporting equity".
"The changes required would appear less than first envisaged," he added.
Hembery said some changes will still be made for Canada, but only to fix the problem of delaminating tyres.
"We're trying to find something that is sportingly equitable amongst the vast majority that allows us to rid ourselves of the tread (problem)," he confirmed.
"We're hopeful we can do that without making such a change that would radically alter the work of any team so far."
