I'd also like to know this as I'm considering some for the same reasons (easy to dismount).
For what it's worth, I tried the 45mm ones many years ago and I couldn't make them fit a frame with fairly tight clearances (420mm chainstays).
Also, I've had some standard road ones in the past, and they worked with 27mm tyres, but were less than ideal.
First port of call would be measure your tyres to determine their actual width.
Think I'm going to shell out for PDW guards for my disc equipped gravel bike (for winter road duties only - the guards will come off again for gravel / offroad and a different set of wheels put in).
Thinking of running 32mm tyres for road - based on collective experience on here can I get away with the 37mm 'road plus' PDW or should I go for the 45mm 'city' version (or will they look stoopid with 32mm tyres)?
Perhaps I should just go larger all round and do 35mm tyres and 45mm guards...
