Friday, during rainstorm, one of our experienced feeder drivers was almost killed when he lost control of tractor and crashed. the drive tires are of poor design. the tread is closed so there is nowhere for water or snow and ice to escape. this was brought to managements attention last winter. after careful study they decided to change to a much better tire but the swap out has been very slow. almost killed a driver. maybe they will wake up and change these tires before the snow flies. now, before you haters chime in about the driver, he is very experienced and has plenty of time with rain and snow. the tires are just a bad design. drivers are talking about sick outs for the first snow.
