Has anyone ever needed to "break in" their drag radials?

Don’t do long burnouts, it overheats the tire and shortens the life. This is why some tire’s don’t wok with lots of tread left, and other still work with cords showing. Also age makes them go bad. Have you ever seen guys that race every week have bald tires that still work, but old ones are spinning even with tread left.

New tires sometimes will work better after a few runs and the surface is roughed up.
