* Brake clearance: 13-inch rims are far too small to clear the brake calipers and rotors on a DeVille.
* Wheel bearing issues: The smaller wheel diameter would alter the suspension geometry and stress the wheel bearings, potentially leading to premature failure.
* Tire size limitations: Finding tires that fit a 13-inch rim and are appropriately sized for a large car like a DeVille is highly unlikely. The sidewall height would need to be excessively large to maintain ground clearance and ride height, leading to poor handling and increased risk of rubbing.
* Speedometer inaccuracy: The smaller wheel diameter would significantly affect the speedometer's accuracy.
In short, attempting to install 13-inch rims would be unsafe and impractical. Stick to the recommended wheel and tire sizes for your 1995 Cadillac Sedan DeVille. Consult your owner's manual or a reputable tire shop for the correct specifications.
