Are 20" rims to big for an e92?

Hey guys,



Might be a stupid question LOL but finally got the money to buy myself some new rims but trying to figure out wether to go 19" or 20"

Had 20" on my old car before but wasn't a BMW



Any pros cons or advice



This is my first BMW so rather do it right the first time then do it over and over again haha



Thanks guys!
