Lewis Hamilton says new guidelines suggested by Pirelli for the Italian Grand Prix could prove to be "a disaster" if enforced.

Pirelli has advised the teams over strict cambers and tyre pressures in the wake of the failures seen at the Belgian Grand Prix, having opted for the soft and medium compounds at Monza. While the guidelines could be changed ahead of Friday practice, Hamilton is worried the initial suggestions are too extreme.

Asked about the findings of Pirelli's investigations into the failures at Spa, Hamilton replied: "I don’t really have an answer for the explanation.

"I feel comfortable coming here and running what we had before. We had a very difficult corner – Eau Rouge – which takes a huge amount of g-force and pressure, which I am sure didn’t help. Here you don’t have that.

"In terms of putting the pressures up, I don't believe that it is the right way – but then they might not do it anyways. I don't really have an answer to the explanation, but I feel comfortable coming here and running what we had before.

"I don't think any of us has tried 5psi more in these tyres because they're not designed to have 5psi more – we work in a range and it's the optimum range. We'll be moving out of the optimum range of the tyre and using a different part of the tyre, which means there'll be more wear and less grip – it's going to be a disaster!”
