Cadillac 2008 DTS - Manual (Page 361)

If your vehicle has a compact spare tire, it should
not be included in the tire rotation process.
Use the four-tire rotation pattern shown. A five-tire rotation pattern may be used for your
professional vehicle, if it has a full-size spare tire
and wheel assembly that matches the original
equipment tires and wheels in size, type and brand.
The correct five-tire rotation pattern is shown.
After the tires have been rotated, adjust the
front and rear inflation pressures as shown
on the Tire and Loading Information label.
See Loading Your Vehicle on page 4-20.
