Cadillac rims and tires

Recommended Posts


The 2009 DTS has standard 17" wheels with a 5-115 mounting hole pattern (5 holes, 4.527" circle) with OEM tire size 235/55-17, unless the DTS came with the optional 18" wheels.

The standard CTS wheels for 2009 are 18" with a 5-120 mounting hole pattern (5 holes, 4.724" circle).

There were different wheel options on both cars, but unless the bolt circle is the same you will need an adapter, which will change the offset - not a desirable thing to do for handling and stability in snow.
