Falcon Tyres is set to increase the price of tyres between 6 per cent and 7 per cent from tomorrow. Industry sources said other tyre manufacturers may also increase prices from tomorrow. Sources in Falcon Tyres, a Ruia Group company, said the company is being forced to increase prices because of the rise in the price of natural rubber, which has nearly doubled to Rs 110 per kg. Falcon, which was recently taken over by the Ruia Group, manufactures tyres for the two and three-wheeler industry. The industry may again increase prices a few months later, sources said.
