A massive wildfire that scorched several counties in central Kansas earlier this year has been deemed "accidental".
Fire investigators say the fire may have been sparked by thin radial tire cables or snow chains.
Investigators found several areas with pieces of tire tread and radial tire cables from a semi tire in the area where that fire started.
According to a new report, those cables caused enough friction on the road surface to spark a fire in several areas.
That fire destroyed around 400,000 acres in Kansas and Oklahoma, more than half of that was in Barber County.
Eleven structures were lost in the fire, which took around two weeks to fully contain.
