Pirelli is planning to alter the shape of its rear tyres next year in order to improve the wear rates, according to an AUTOSPORT report.

Although the Italian tyres manufacturer has received positive feedback about how its tyres have performed during its first season as the sole supplier to F1, it is still planning to make the changes.

Paul Hembery, director of motorsport for Pirelli, revealed that the tyres will be boxier in 2012 as a result of the search for improved wear.

He told AUTOSPORT: “The shape, yes [will change]. To get better wear on the shoulder. It’s hard to quantify by how much it’s going to change.

“At the moment we’re not utilising the full footprint there, which we knew about, but we had to try and block some of the development because we had so little time and we wanted to at least give the teams some fixed data that we’re new to the sport and not wanting to keep making changes.”

Hembery stressed that the changes only come as a result of the Italian manufacturer seeking to get better performance out of its tyres.

“It’s Pirelli wanting to improve its product, from our point of view, improve the wear, improve the shape of the wear profile across the tyre,” he added.
