This is my understanding, that the strap/toe clips force a really stiff sidewall tire down and into the depression a and holds it in place.
I've seen some continental touring plus tires that are like this, very stiff sidewalls, throw in a certain rim combo and its been a real bugger.
decades ago I had some specialized city nimbus something tires that were like this also.
