Reuters, PEHub.com and other media are reporting that at least two private equity firms are in talks to buy Warburg Pincus LLC’s majority stake in Alliance Tire Group.

The reports said the deal could come in at $400 million.

Singapore-based Temasek Holdings and KKR & Co. were named as the suitors and were said to be “in advanced talks” to buy the Warburg share in the tiremaker. U.S.-based private equity firms Advent International and TPG Capital also were reported to be interested.

Warburg Pincus, which invested in Alliance in 2007, wants to sell its 72% stake in the tiremaker, which is headed by CEO Yogesh Mahansaria.

ATG was expecting to post 2012 global sales of about $600 million, and operates two ag and OTR tire plants in Israel and India. In North America, the company distributes ag, OTR and medium truck radials.
