I've never "broken in" tires on anything but a sport bike, and never had a problem. But I get the idea. I would just wash the tires first. I do my own tires, so I always clean the tires and wheels before putting them back on the bike.
The D404 is an economy tire. I would not expect great mileage out of it. The best thing about these tires is the wide range of sizes they come in. You can get them to fit many vintage bikes.
