This is very very obscure but its a scene that scared me at the time and I’m wondering if its actually from a movie/TV show or was it something I dreamt…
I saw this a long long time ago and all I can recall is the scene where children were playing in the countryside and they get themselves a rear tractor tyre and think it’d be a good idea to get one of them to sit inside it and then push it down a very steep hill.
Of course it all goes horribly wrong with the tyre going a lot further and faster than they expect.
There’s a similar scene in To Kill a Mockingbird. Scout is in the tire. It doesn’t go down a steep hill, but does go faster and further than expected - right into Boo Radley’s front yard (the scariest person they know - at that stage). Because it’s set in small town South, the kids are dressed in dungarees and it seems quite rural. It would have been scary as a kid since Scout’s brother and neighbour were convinced she’d be attacked by Boo.
Can’t speak for the OP, but that is definitely the one I remember. One of the comments in the ratings does mention boys rolling down a hill in tires. And the South African and then New York settings ring a bell.
