I got some MOPAR cab/police wheels from a junk yard. They work just fine on some 10" slicks that I have. Go to big early season swap meets looking for used slicks. Check the wear holes across the tire face for the amount of rubber left. Sometimes you can even get them mounted on rims for a good deal. Look them over closely though for damage. You don't want to lose one at 100 mph.
