Ceat has decided to hike its tyre prices by 3-5 per cent from this month-end to offset surging rubber prices for the second time this year. Raw materials prices have gone up to an all—time high, touching Rs 250 per kg of natural rubber. The price revision in the range of 3-5 per cent is inevitable and it would be made effective from the last week of this month across the country. Earlier, the company hiked tyre prices by 4-5 per cent in January this year.
