1996 Cadillac Deville on 22's?
 

Alright, i know somebody had to ask this question already but here it goes!
Can you put 22s, 8.5, with the thinnest tires on a 1996 Cadillac Deville with a back skirt?
I seen people do it, but is there modifications that i need to do in order for the 22s to fit?
Thanks everybody!
