What are the cons with putting 22inch rims on a factory chevy caprice suspension?

I want to put 20's or 22's on my 1993 chevy caprice. I don't want to change a lot of suspension parts or shaving off metal. Can I install 20'or 22's on the car with out worrying about- i know about the pot holes- I just gotta look out for those.|||your fine putting up to 24 inch rims on that body style caprice... the only downside is your going to get a lil rub when you turn and low series of tires means worse problems with holes and bumps and stuff.... but 22 are fine|||It would be best to buy a lift kit from kingofthestreet.com and you can put dubs or 22's on it and want have to worry about wheel weld clearance..
