sure will.
yes they will fit easily with no rub or lift needed, i have a 94 model roadmaster with 24's on it and they fit perfectly.
You can call or go into a GM dealerships service department and they have all the specs on your Roadmaster including the maximum size of rims you can put on without messing up your spedometer..etc.. Hopefully this helps.
YES
22 inch rims will fit on a 97 Buick Park Avenue , but they will rub. 20 inch rims would be a better option if you don't your rims to rub.
