Police are investigating an incident where around 60 car tyres were dumped in the roadside ditches of Conrhenny Road, next to Conrhenny Plantation, just north of Douglas.
Officers were told on Monday that the tyres had been left in two piles, either side of the road.
They believe the tyres hadn't been there for long, and add that a large vehicle would have been needed to carry so many to the site.
Police are keen to hear from anyone who may have information on the incident.
If you can help call them on 631212.
