Will 20 inch rims fit on your 08 cts Cadillac?

Yes, 20-inch rims can fit on a 2008 Cadillac CTS, provided they have the correct bolt pattern, offset, and width. The factory specifications typically allow for 20-inch wheels, but it's essential to ensure that the tires used with the rims do not rub against the wheel wells or suspension components. Always consult a professional or reference the vehicle's specifications before making modifications to ensure proper fitment and safety.
