MEXICO CITY (Reuters) - French tyre maker Michelin (>> Michelin (CGDE)) plans to build a $510 million plant in central Mexico that will produce around 5 million tires a year and could be expanded to produce another 5 million annually by around 2020, documents showed.

The plant in the state of Guanajuato will begin production in 2017, and will produce passenger and light truck tyres, mostly for the North American market but also for Europe and Asia, according to two documents seen by Reuters.

Some of the production will be sold directly to customers as replacements, while others are destined for production lines of Mexico's growing auto sector.

"Michelin has a long-standing commitment to strengthening its operations in North America. While Michelin's interest in expanding in the region has been the subject of speculation in recent months, the company is not announcing any specific details at this time," a company spokesman said in an emailed statement on Wednesday.

Guanajuato has become a major hub for automakers, with both Toyota (>> Toyota Motor Corp) and Ford (>> Ford Motor Company) announcing new plants in the state last year.

Rival tiremaker Goodyear Tire & Rubber Co (>> Goodyear Tire & Rubber Co) also announced a new $550 million plant in the central state of San Luis Potosi last year.

Mexico, the world's seventh largest auto producer according to the International Organization of Motor Vehicle Manufacturers, entices auto producers with its low labour costs, free trade agreements and proximity to the United States.

The plant is expected to create over 1,000 jobs, both documents showed. Reuters could not verify when construction would begin but a Mexican official familiar with the talks said that the announcement could come as soon as this month.

Depending on market conditions, the plant could be expanded to produce another 5 million units annually and employ an additional 750 people by around 2020, one of the documents said.

Michelin, based in Clermont-Ferrand, central France, is pushing an overseas expansion strategy while cutting costs and is struggling to defend its namesake brand's higher prices against competition from Chinese brands.

In November 2015, the company said it planned to close some European plants and boost production at others in a reorganization aimed at coping with tougher competition and the impact of years of economic crisis in the region.
