I recently bought an old Eastman ten-speed. It's got 700x23 tires on steel rims.
The walls of both rims bend out slightly, maybe 10 degrees each. I'm not sure if they were built that way, or if they've bent slowly over time.
I want to know if this bike is safe to ride with the tires at 80-100 psi. I don't want the (front) rim to explode at 40mph.
Does the fact that they are steel (instead of aluminum) remove the risk of a blowout?
Here's a picture:
