E-bike rims: can I use them on my touring bike? I am touring with my MTB, now for 4 months.
I have been using really good Pacenti 29er rims, but just 2 days ago I cracked the rear one.
I am carrying a lot of weight and Pacenti (after I contacted them, great guys) made me notice that the rim even if strong for MTB is not made to carry that load.

I am thinking to replace the rims with E-bike ones, because they are actually made for heavier bikes.

Do you think it is a good idea?
The rim I would like to use is a:
DT SWISS Rim 545d 700c 28'' black 622-19 vl 6,5mm 36 hole simply eyed
Does that rim state a load? How heavy are you touring? Not much of the strength of a wheel come from the rim anyway, at least as regards vertical loading. MTB touring can put extra shock loads on a wheel compared to road touring. 

A rear e-bike rim has a lot of stress on it, and not just from the unsprung mass of a hub motor but the shorter spokes. So it might be good, but the actual load could easily be less than a loaded tourer.

The e-bike I've ridden is about 30kg bare. That's less than the luggage when I went bike camping. The rider is almost always the heaviest part of the system.

The toughest wheels are probably those built for touring tandems. 40 spokes are common, 48 not unknown.
