the larger the wheel the less likely to have interference problems.  which slapping some 22"s on your car will make you look like a pimp, it will also be easier to avoid problems.  most 17-18" inch wheels have good cleanance on the front.  most 18-19 have good clearance on the rear. (they clear the parking brake cable bracket on standard trailing arms.

 

also you have to consider the tire width versus wheel width.  for example.

 

10 inch tires work well on 8 inch wheels.  like a 255/60 R15...  but what you have to watch for is putting tires any wider than this on an 8 as you will get bulging and this can increase clearance problems. 

 

also wheels dont necessarily need to be "centered", that is the offset doesnt need to be half the width.  you should try to keep it close, but dont let an inch out of center offset change your mind on good wheels.  just dont do any stupid ricer crap where the wheel is 3 inches out of center.
