Going to have to disagree with that, 45mm is still too big for any kind of semi competitive club racing on carpet.
If you want to get some life out of your tires try running a blue or green compound. Both of those will give you a lot more life then some of the softer other types of rubber. You could cut them down to something like 42mm and still get a dozen or more runs no problem.
