PARIS, June 17 (Reuters) - French tyre maker Michelin announced on Wednesday a plan to cut 1,093 jobs on a voluntary basis as part of a restructuring of its facilities as it battles with falling demand from carmakers.

Michelin added it would also invest more than 100 million euros (US$139 million) at its Clermont-Ferrand research and development centre and hire around 500 people a year over the next three years.

Michelin's rival Continental , which is also struggling with a sharp drop in orders from the auto industry, has already announced the closure of plants in France and Germany, resulting in the layoff of hundreds of workers.

Earlier this year, US rival Goodyear also said it planned to cut 5,000 jobs worldwide this year.
