In the past ten years Qingdao Qizhou Rubber Co. Ltd. has striven to expand its business in export markets and to facilitate this invested approximately US$14 million in the construction of a OTR tyre new factory in 2003. Since the completion of the facility in Qingdao (Shandong Province) in September 2004 the OTR tyre specialist Qizhou has been able to produce around 100,000 tyres per annum. Central to the company’s range is the “Marcher” brand, through which the manufacturer of the “world’s largest OTR tyres” (59/90 R63) is represented in most corners of the globe and in the original equipment market, delivering to, as an example, LeTourneau Technologies for fitment to its dump trucks. The US firm utilises crossply “Marcher” OTR tyres in size 70/70-57 84PR with a L4 tread; deliveries to Australia and North America are made and even involve the largest available LeTourneau dumpers, disclosed Qingdao Qizhou export manager Gavin Liu.
