Schwalbe Marathon E-Plus Tire

This is the ultimate e-bike tire. Sure, it's a little heavy, but in return it rides superbly, offers unmatched traction, and it is nearly impenetrable (read: no more flats!). From the manufacturer:

Flat-less especially for E-Bikes. Maximum riding safety at high speeds and on long tours.

Highest Marathon quality tires refined for the special demands of E-Bike Safety. Schwalbe puncture protection level 7.

The patented SmartGuard protection layer is additionally supported by two layers of RaceGuard fabric. This “Smart-DualGuard” protects even better against sharp objects.

The ADDIX-E compound, specially developed for the use on E-Bikes, provides outstanding grip even at high speeds and also maximum durability. 

Riding pleasure: Marathon E-Plus rolls surprisingly well thanks to high-tech materials. The “antiaging” sidewall prevents for much longer the unsightly cracks caused by use with low air pressure. The new carcass construction reinforces the sidewalls with a further layer of fabric and thus stabilizes the tire for even more load capacity. 

Design: The tread profile of the Marathon E-Plus is modern and dynamic. The E-Plus’s tread depth makes is extremely versatile for touring and trekking. 

E-Bike: Of course, ECE-R75 certification makes the tires ready for E-Bikes of all classes. The available sizes are consistently geared to the requirements of modern E-Bikes.
