Some of the heaviest parts of the tire (bead/beadlock and tread) are smaller
diameter than a 29'er tire (650b+ still drops the BB almost an inch comparing
the exact same bike with 29×2.3) so the total weight increase for same/same
650b+ x3″ vs. 29×2.3″ tire is likely ~200 grams max.
There are lots of reasons Plus isn't going to be the end-all-be-all, and there
are geo concerns re. just throwing in a set of niner hoops when you want to go
for an all day pedal, but I think tire concerns could easily be addressed if
hitting a weight target wasn't a concern. 29ers had exactly the same
evolution.
