Can't use tubes in Weld Wheels Draglites?

using tubes, need to coat talcum powder inside of tire. it keeps tube from being pinched. stem placement is very important also.
I do this for my dirt bike tubes, except I put the powder on the tube. Another thing is once the bead is set, let all the air out so the tube can untangle any areas where it may have folded over itself. After that you should be good to air it up like normal.
