The 2007 Cadillac DTS was designed for much smaller wheels. Trying to fit 22-inch wheels would likely cause:
* Wheel rubbing: The larger diameter and potentially wider width of 22-inch wheels would significantly increase the chance of the wheels and tires rubbing against the suspension components, bodywork, or wheel wells.
* Brake caliper clearance issues: The larger wheels might not clear the brake calipers.
* Suspension problems: The increased unsprung weight (weight of the wheel and tire) would put extra stress on the suspension components, potentially leading to premature wear and tear or even failure.
* Speedometer inaccuracy: The larger wheels would alter the speedometer's accuracy.
* Ride quality issues: The ride would likely become much harsher and less comfortable.
While some aftermarket modifications *might* be possible, they would be extensive and expensive, and the results would likely be unreliable and unsafe. It's highly recommended to stick with wheel sizes that are specifically designed for the 2007 Cadillac DTS. Check your owner's manual or consult a tire shop for the recommended wheel sizes.
