Camso, which had net sales of $1 billion, designs and manufactures off-the-road (OTR) material such as rubber tracks for farm equipment and snowmobiles, and Michelin said its acquisition would create a world leader in the OTR sector.

"Michelin will benefit from all of Camso's skills in the off-the-road mobility markets and Camso from the full range of Michelin's expertise in the speciality markets," said Michelin chief executive Jean-Dominique Senard in a statement.

Michelin added it had also increased its estimate of synergies from its earlier acquisition of Fenner to 60 million pounds ($79 million) from 30 million.

Michelin shares were up 2.3 percent in late session trading.
