I was wondering if anyone knows a decent source to pick up a few cheap plastic or rubber tires, similar to the Matchbox cars of yesteryear line? I thought maybe there would be something through railroad supply (O-scale would be fine - anything between 1:43 and 1:55, really), but I actually haven't found any cheap ones going that route. Also a couple of die-cast ones on online shops, but I'm not really looking to spend real money here.
Was hoping maybe someone would have some broken or cast-off wheels that could be shipped cheaply on fleabay, but nothing there.
I suppose I could buy more matchbox yesteryear cars and just rip the wheels off, but that seems like kind of a waste! Might try the local model railroad shop and try my luck, but if anyone knows any alternative, that would be keen!
