The driver of an 18-wheeler hauling bread Tuesday was able to disconnect the tractor when a tire caught fire, but the trailer part of the rig was toast. Bulloch County Fire Capt. Christopher Ivey said volunteer firefighters were first dispatched shortly after 11 a.m. to the eastbound lane of Interstate 16 around mile marker 116, where a driver pulled over because of a “smoking tire,” he said. While firefighters were en route, the smoking rubber caught fire and turned into a blaze requiring two tankers and the assistance of a third from the Statesboro Fire Department, according to information dispatched over emergency responder radio channels.
