I recently purchased a 2006 Cadillac CTS HFV6. I love this car, great ride. I have a question. It currently has 225/55R16 tires on the chrome 16" rims. The tire diameter is 25.7 inches. My old car (RX8) had 245/40R18 tires on it (25.7 inch diameter, sweet!!). I know that the tire will fit in the wheel well. Here is my question: I would like to purchase the 18" CTS-V rims and mount these tires on there for my summer set. Will the 18" CTS-V rims fit on my CTS HFV6?? I would assume...just making sure the bolt pattern is the same.
And if it is...I'm looking for the 18" CTS-V rims, new or used.
