This is true for runflat tires on automobiles (BMW). I wonder if its the same for bicycles?
marathon plus has a stiffer casing, extra layers and a harder rubber so yes, the side walls are stiffer, less compliant... I get similar effect between MTB tyres (soft sidewalls) and gravel tyres (stiff puncture resistance) and have to run lower pressures (-8psi) or the harshness and vibrations hurt my arm joints.
