Earlier this year, the FIA opened up the tender process for F1's official supply contract from 2025 to 2027, with the possibility of it being extended until 2028.
The deadline for applicants was May 15, with the FIA now going through the process of evaluating the proposals from interested parties before making a call on who the approved bidders are on 16 June.
The successful candidates will then move on to the next stage of the process, which will include discussions with F1's commercial rights holder.
The last tyre tender process, from 2020 to 2023, saw Pirelli face a challenge from South Korean company Hankook.
Pirelli was then granted a one-year extension until the end of 2024 due to the delays in the introduction of new technical regulations prompted by the COVID pandemic.
With the deadline for applicants for the 2025-2027 tender having passed, it is understood that Pirelli is not alone in having put in a bid for the new tyre contract.
And while there has been no confirmation from the FIA about the number of candidates nor their identity, sources have suggested that Japanese company Bridgestone has applied.
Bridgestone was last involved in F1 from 1997 to 2010 and had been the single supplier from 2007 onwards following the decision of Michelin to quit the championship at the end of 2006.
Since leaving F1, Bridgestone has remained involved in major Japanese categories as well as other international series. Its Firestone brand is the sole supplier of IndyCar.
Speaking to Motorsport.com recently, Bridgestone's manager of motorsports planning Eiichi Suzuki said that the company was evaluating involvement in other series, including F1.
"We are always thinking about what and how we can best supply our motorsports activities in global categories, including F1," he said. "Of course, we are conducting research on such matters."
Bridgestone itself has, however, declined to confirm whether or not that interest has extended to it formally applying for the tyre tender contract.
A spokesperson for the company said: "Bridgestone has a heritage of over 60 years in motorsports and we will continue to pursue sustainable global motorsports activities. However, we refrain from commenting on any particular categories."
