Exactly. What surprises me it took 8 posts for the obvious to be stated.
Not only rubber but the nose wheel and surrounding structure must take a hammering. Bend metal often enough and long enough, it will crack and break.
What about the increased risk of FOD due to the higher power needed for taxi on the live engine?
