The main thing about going to larger wheels , is the lower profile tire that go along with them. With very little sidewall to help absorb the shock of hitting pot hole etc. the wheels take the brunt of the impact. I talked with our most popular tire & wheel dealer before I bought wheels a few years back. His advice was if i drive it on the street often done get them. He said that almost every set of wheels 20 or larger, the owners were back in less than a month, asking him to straighten their wheels, where they hit potholes and other road hazards and bent the rims. Said he can do it a couple of times, after that, the integrity of the wheel is very much compromised. Just a thought.
