The Cadillac CTS is known for its sleek design and powerful performance, and upgrading to 20-inch rims can significantly enhance its aesthetic appeal and even handling (depending on tire choice). This guide explores everything you need to know about equipping your Cadillac CTS with 20-inch rims, addressing common questions and concerns.
What are the benefits of 20-inch rims on a Cadillac CTS?
Larger rims, like 20-inch options, offer several visual and performance-related benefits:
-
Improved Aesthetics: 20-inch rims dramatically alter the CTS's appearance, giving it a more aggressive and modern stance. The larger diameter fills the wheel wells better, creating a more substantial look.
-
Enhanced Handling (Potentially): While not guaranteed, the right tire combination with 20-inch rims can improve handling. Lower-profile tires often accompany larger rims, leading to a stiffer sidewall and potentially better responsiveness. However, this comes with a trade-off in ride comfort (discussed later).
-
Increased Braking Performance (Potentially): Larger rims can sometimes accommodate larger brake rotors, though this depends on the specific rim design and caliper clearance. Larger rotors can improve braking power.
What are the drawbacks of 20-inch rims on a Cadillac CTS?
While aesthetically pleasing and potentially performance-enhancing, 20-inch rims also present some drawbacks:
-
Reduced Ride Comfort: Lower-profile tires necessary for 20-inch rims generally lead to a harsher ride. Bumps and imperfections in the road will be felt more acutely.
-
Higher Cost: 20-inch rims, tires, and installation are significantly more expensive than smaller options. Replacement tires will also be more costly.
-
Increased Risk of Damage: Larger rims are more susceptible to damage from potholes, curbs, and other road hazards. Repair costs can be substantial.
-
Potential Speedometer Inaccuracy: If the overall diameter of the wheel and tire combination is significantly different from the factory setup, your speedometer might be slightly inaccurate.
What size tires should I use with 20-inch rims on my Cadillac CTS?
The correct tire size is crucial for optimal performance and safety. You'll need to consult your Cadillac CTS's owner's manual or a tire size calculator to determine the appropriate tire aspect ratio and width to maintain the correct overall diameter and avoid speedometer inaccuracies. Using an incorrect size can affect your car's handling and speedometer accuracy. A tire shop can also help determine the best fit for your specific year and model.
Will 20-inch rims fit my Cadillac CTS?
Not all 20-inch rims will fit every Cadillac CTS. The fit depends on the specific year, model, and trim level of your vehicle. The bolt pattern (number and spacing of lug holes), center bore (hole in the center of the rim), and offset (distance between the mounting surface and the centerline of the wheel) must be compatible. Consult a wheel fitment guide or a professional tire installer to ensure proper fitment.
Where can I buy 20-inch rims for my Cadillac CTS?
20-inch rims for the Cadillac CTS can be purchased from various sources, including:
-
Authorized Cadillac Dealers: They offer genuine Cadillac rims, ensuring a perfect fit and quality.
-
Aftermarket Wheel Retailers: Many online and brick-and-mortar retailers offer a wide selection of aftermarket rims at various price points. Be sure to check compatibility before purchasing.
Are there any specific brands of 20-inch rims recommended for the Cadillac CTS?
