I have a 93 Z and am about to purchase 20' rims. Anyone know what size tire i would need to avoid rubbing, or should i go with a smaller rim size??

I just looked at Discount Tire (http://www.discounttire.com/dtcs/tirePlusSizes.do?rcz=76048&mk=CHEVROLET&rc=TFWINT&yr=1993&vid=000324) to check, and they don't have any twenty inch tires listed for a Camaro. I would call around to different tire stores to check and see what they say.

WHY....................JUST WHY????????
please tell me their not spinners.........lol
