Pirelli is working with the FIA to avoid a repeat of the post-race confusion at the Italian Grand Prix.
On the grid at Monza, both Mercedes cars were found to have rear tyre pressures that were below the minimum permitted value set by Pirelli. A stewards' investigation found that the pressures had been set at the correct level when the tyres were fitted to the cars, but then dropped below as the team awaited the start.
To avoid doubt being cast over future results, Pirelli wants to set out a clear procedure for setting and checking the pressures on cars.
"We will be defining, together with the FIA, a clearer procedure enabling the teams to more easily follow the rules regarding tyre usage," Pirelli motorsport boss Paul Hembery said. "This is important to avoid any misunderstandings, by giving the teams more precise indications to comply with, thus avoiding what happened to Mercedes in Monza."
Pirelli is bringing its two softest compounds to this weekend's Singapore Grand Prix.
"As this is a street circuit, we've nominated the two softest and fastest tyres in the range: they offer the maximum mechanical grip and a rapid warm-up, which are two keys to success in Singapore," Hembery said. "There are lots of factors for the teams and drivers to consider when planning strategy: the unusual track temperature evolution, a big performance gap between the two compounds, the need to save fuel over the long and demanding race distance, as well as the high likelihood of a safety car, which has featured at every race in Singapore so far.
"Because of all these variables and also the assorted street furniture - painted white lines, manhole covers and so on, which have caught out a few drivers in the past - the work done in free practice to capture all the necessary tyre data will be even more important than usual."
