Kentucky State Police say West Side Towing was pulling a trailer from Owensboro to Bowling Green when a tire blew out on the trailer.
They say part of the trailer then caught fire.
It happened on the southbound lanes of the Natcher Parkway near mile marker 18 in Warren County.
No one was hurt.
As a precaution, the northbound and southbound lanes of the Natcher Parkway were closed for nearly an hour but have since been re-opened.
