Gander RCMP say poor tire condition is believed to be a factor in two of three recent crashes on the Gander Bay Road.
Police say all three crashes occurred on Sunday at various times throughout the day. Two of the vehicles that came to rest on their roofs were found to have tires in poor condition with very low tread left.
The third vehicle had good tires and remained upright when it left the road.
RCMP are encouraging drivers to regularly check the condition of their tires.
