The wheel mounting specification for the 2007 Cadillac DTS is 5×115 mm. This designation describes a five-lug configuration with a bolt circle diameter of 115 millimeters. This measurement is critical when selecting aftermarket wheels to ensure proper and safe fitment.
Correctly matching this specification is vital for vehicle safety and performance. Using wheels with an incompatible configuration can lead to vibration, damage to the wheel studs, and potential wheel separation from the vehicle. The adoption of this specific arrangement in the DTS reflects automotive engineering decisions aimed at optimizing load distribution and structural integrity. Its legacy is rooted in General Motors’ design standards for full-size sedans during that era.
