I have the MTR's. They really don't balloon as much and I didn't tape mine at all, the ribs are not only on the inside of the wall, but they go around the tires as well. The sidewall ribs make the sidewall a tad stiffer to reduce sidewal flex. Also, the sidewalls aren't narrower as in height, but they are width wise compared to the reg MT tires.
the ribs do add weight which I did not like too much. I would use the non-offset velo's...
