In a Jan. 30 stock-exchange filing, Shanghai-based Sailun disclosed a plan to invest $311 million in its plant in Svay Rieng to boost passenger tire capacity by 12 million units a year, or double the increase Sailun proposed in October 2023. Once completed, the production capacity for passenger would rise to 21 million units per year, in addition to 1.65 million truck and bus all-steel radial tires.

The construction period for the new project is expected to be 16 months, but the tire maker did not state when this work would start.

Tires manufactured at the factory are primarily destined for North America and other overseas markets, according to Sailun.

Sailun started trial production of passenger tires at the Svay Rieng plant in November 2021 and added capacity for truck/bus radials in 2022.

The plant is the company’s second overseas factory, alongside a plan it opened in 2013 in Go Dau, Vietnam.
