In a further blow to Red Bull's hopes ahead of the Italian grand prix, Pirelli has issued yet another clampdown on its guidelines about tire camber.
It had already emerged that, after the tires on the winning RB7 cars worryingly blistered at Spa two weeks ago, F1's official supplier had told teams to limit their camber angles to just 3.75 degrees at Monza.
Previously, the recommendation was 4 degrees, with designer Adrian Newey admitting that the camber on the Red Bulls in Belgium was set slightly higher.
Germany's Auto Motor und Sport reports that the camber directive issued by Pirelli for Monza is actually just 3.25 degrees.
As recently as Hungary in late July, the recommendation was 4.5 degrees.
Pirelli chief Paul Hembery said Monza is "very hard" for the tires, with aggressive camber increasing the risk of overheating "especially with the hot weather that is predicted".
McLaren's Jenson Button thinks the new cautious approach "will put some people in trouble" in terms of lap time.
UPDATE
Friday, it was found that Pirelli could involve the FIA to ensure the safety of its tires.
BBC pit lane reporter Ted Kravitz confirmed that the FIA could "enforce as a rule" Pirelli's recommendations.
He said Hembery is monitoring the situation and will act if he thinks teams are "flouting" the guidelines. "We will reserve judgement about contacting the FIA," Hembery is quoted as saying.
The BBC's Natalie Pinkham added that the FIA will indeed "force teams" to follow the recommendations this weekend, with Pirelli concerned about overheating on the ultra high-downforce Monza layout.
"That means any team doing what Red Bull did in Belgium will be reported to the stewards," she said.
