They dont really need to be round like motorcycle tires to have good traction unless the track that you're racing on is lower grip then you might need them this way. I have never had any luck running them outside to break them in for inside.
Good advice Mr. Kane. I also know guys who have tire truers, or much more scuffing machines, who will spin them up, and apply a rag with the track's chosen tire treatment, and hold it on the spinning tire until it smokes. They let it cool, then repeat the process, and then run the them in for a pack. Seems to work fairly well.
