RFT have a different turn-in feel and address road undulations less well than conventional tires. This is easy to feel at any speed. However, most people do not notice/do not care.
An RFT is a hazard to rims only when inflated to a higher pressure and the very stiff. They are less forgiving on potholes as a result.
An RFT is no more dangerous to a rim once deflated than a normal tire, less so in fact as the stiff sidewall will help protect the rim.
I intensely dislike RFT and run conventional tires. I assume the little risk that I may have a flat and will be accordingly inconvenienced. Others see the equation differently and use RFT. Neither side is "right;" it is merely a preference.
