I guess that's your prerogative to put 22" on your DTS, with low-profile tires, it will probably look nice. And you may even keep that Cadillac ride...for about a year. After that expect to start experiencing ride issues. On a 07, let's start with popping sounds when making hard turns, choppy ride, ELC going crazy, struts shot. I am no DTS expert but I am going on 7 years with my 2011 Premium and just regular maintenance cost is no joke for riding stock. I tried 17" wire rims for about a year. Worst thing I have ever done to my car to date. Those heavy steel rims took out my front end suspension on both sides all at once. Everything, struts,strut mounts, LCAs, end links, sway bar bushings, hub assembly. I am staying super clean and stock. Vogues is the only aftermarket.
