no idea whether they are the original wood rims. They appear to have been painted an off silver at some point in their life. Once I have time I will take a closer look to see if their is any army green paint ( I think the original colour the rims would have been painted) hiding under that silver.
I currently have 8 road/cyclocross bikes, 5 mountain bikes, and 2 bmx, that my family of four rides on an ongoing basis, that I maintain and replace tires on every few years. So in the grand scheme of things, it’s not a big deal to add a couple antique bikes to the rotation. Tires may cost more, but I suspect their lifespan will be a lot longer than the ones that get daily use.
