Yinbao Group: 57-inch Bias Tyre Lasts 4000 Hours+

Chinese OTR tyre manufacturer, Yinbao Group, has reported that its giant bias OTR tyres (4000-57) are achieving service lifetimes in excess of 4000 hours. Yinbao Group highlights one particularly example of a 4000-57 tyre the company shipped to South Africa last year and which is still in “good service” despite being in operation and exceeding 4000 hours to date. Another product (in size 45/65-45) has reportedly been in use for more than one year.
