Continental estimates that the 2011 UK car, 4×4 and van tyre market will equate to 33 million units despite estimates from other leading tyre manufacturers earlier in the year suggesting demand could have been in for a double digit drop. Speaking at the tyremaker's annual market trends briefing in London, executives from Conti's UK operation (Continental Tyre Group Ltd) explained that the market has “remained static, with a number of evident developments, such as an increase in the part worn market due to the scrappage scheme.” Continental now estimates that part worn sales equate to 2 – 3 million units a year, with sales of these used products estimated to have increased by up to 50 per cent of the traditional and widely accepted 2 million units annually figure.
