Paul di Resta suffered a tire failure at high speed entering the pit straight during Friday’s second free practice session for the Spanish Grand Prix. Pirelli announced shortly thereafter that it will investigate the matter further.

“Obviously there was a problem in the final part of FP2 that affected the medium tire on the Force India of Paul di Resta and we’re going to investigate the cause of that fully,” Paul Hembery, Pirelli’s motorsport director, said in a post-practice release.

While drivers seemed happy with Pirelli’s newly modified hard compound, which was introduced this weekend, the medium appeared to have been affected by higher tread temperatures. Hembery explained further when asked by Autosport after practice.

“It doesn’t look pretty when you get the tread coming away like that,” he said. “If anything like that happens, it tends to collapse the tire on to the rim, so it did not look good. This year we are seeing the tread coming away. Visually it looks rubbish. We don’t like that and we are looking at seeing if there are things we can do to eliminate that.”

For better or worse, Pirelli’s 2013 tire compounds have been in the news more than you might like to hear or see this year.
