Schwalbe Marathon Plus are not only ebike-rated they are rated to 50kph much faster than the 25kph electric bikes in the EU are setup to go.

Continental Tour Plus are ebike rated but only have a 25kph speed rating.

Speed isn't the problem with these small diameter tires, most are overstressed because the ergonomics of the bikes has 80% of the weight on the already heavy electric wheel rear end. Add electric motor torque to this and the walls just can't handle it.
