After having several encounters with what is left 18-wheeler tires, I have had enough of trying to miss these on the highway or having no choice but to hit it with my car. I have seen these cause accidents from people trying to miss these and the aftermath of the hit on my vehicle along with other vehicles.
These are dangerous to all drivers (18-wheeler and others) because they do cause accidents, cause a lot of damage to cars and trucks, and make the highways look horrible with what is left of re-tread tires on the side of the road.
