In 2010, the Cadillac CTS comes in various trim options and two engine sizes. Depending on the trim level, the car can be fitted with different tire sizes — P235/55R17 tires are found on the Base and Luxury trims, while P235/50R18 tires are on the other trims. The rims on this model range from 17 to 18 inches in diameter and are 8 inches wide. Despite the tire size differences, the bolt pattern for the wheels remains the same across all trim levels at 5x120. The center bore diameter is also consistent at 66.9mm. Each wheel on the 2010 CTS is secured with five lug nuts, with threads that measure M14 X1.5.
The 2010 Cadillac CTS features a wheel bolt configuration of 5 bolts with a spacing of 120 millimeters.
