Although some drivers are relishing the heavy wear rate of the new Pirelli tires, confident it will improve overtaking, others have not been as impressed.

In fact, Trulli, one of the most experienced drivers on the grid, reckons the tires are too inconsistent, the balance is out and that it's a sign that Pirelli haven't done enough development.

"I think something is still missing in the development, because the tires aren't balanced yet," Trulli told Autosprint magazine.

"I think this is the biggest problem to face at the moment. Pirelli says that this is what the FIA asked them to do, to have tires that wear quickly, but I don't think this is the problem.

"In my opinion tire wear is secondary compared to the tire’s balance problems, because at the moment you get on the track with a new tire that initially is understeering, and after three laps the behavior is the opposite, that is impossible oversteering."
