Only at the bottom where they bump into the rails
Yes at a microscopic level there is some flattening due to deformation of the wheels caused by the weight of what is sitting above them. The rails also deform slightly under load as well.
Herb? Got that air pump handy??

Yes, trains do get flat tyres A diesel locomotive on a tourist railway near me was taken out of service due to eight flat tires.The tires were so badly worn they couldn't be profiled. The wheels needed new tyres but the cost was prohibitive.Unfortunately the tourist railway is no longer operational.............Peter.
