Pirelli thinks it possible that the mystery tyre vibrations that occurred at the Belgian Grand Prix could return in Italy this weekend.

Formula 1's tyre supplier is still seeking answers this week as to why the rear tyres of several cars were seen to deform in a strange way on the exit of low-speed corners.

It was the first time such a phenomenon had been witnessed and, although it posed no risk to the structural integrity of the tyres, the vibrations did contribute to damage to Lance Stroll's Williams in qualifying.

Pirelli's F1 racing manager Mario Isola suspects that the effect could return at Monza, although he does not think it will be as extreme this time.

"It is possible because you have big braking and big traction on the exit of the low speed chicanes," he said.

"But we have also to understand the effect of the grip, and the roughness of the tarmac. I am not sure we have the same at Monza."

Isola said that work would take pace at Pirelli's Milan factory this weekend to better understand what was happening at the Belgian GP.

"We are checking the frequency of the vibrations and we continue to investigate," he said. "It is a new effect, similar to what we have had on the sidewall [in the past] but it is on the tread.

"When we spoke to the teams they were confident it didn't create an issue and the race was okay, so they were right. And in our investigation, we cut a lot of tyres during the race weekend and we didn't find anything to support any conclusion.

"So we need to carry on investigating and checking. It is at low speed traction so it is an effect of the traction, and then we will look at the data from the race as well."
