What percentage of typically needed track repairs would be eliminated by using rubber track?
I don’t pretend to know the answer myself, it may have more problems for all I know.
"The CV90 displayed in Paris is one of the largest to run on continuous rubber tracks (actually, rubber with steel cores). With the aid of its supplier, Soucy Track of Canada, BAE Systems has tested rubber track to 28 t on the CV90 and is working on "limp home" solutions for repairing battle damage: operators have been resistant to rubber track because the links can't simply be replaced in the field. Advantages include much lower noise, better grip in snow and higher efficiency."
