15x8 steelies

The dodge Cop Car steel wheels were 15 x 7 with the 4.5" bolt pattern

Correct, but for some reason I don't care for the cop car wheels. Regular steelies, bring it on. Cop wheels, not so much. Besides, the wheels on the back of the wagon now are already 15x7 with 255/60-15's on them. I'd like to go to 275/60-15 to fill out the wheel well a bit better. I need new wheels and tires on the wagon anyway as the ones on there are for my Dart. I just stuck them on the car to drive it for shake-down time for a while.
