Cadillac XTS Forum Discussion, Compact spare and rim in Current Cadillac Vehicle Discussion; Would someone please point me in the right direction? I'm looking for the GM part numbers of the 19 inch ...
After some "googling" it appears that regardless of which wheel size the XTS has (19" or 20"), if it has a spare, it is listed as: "Compact Spare Tire T135/70R18 BW"
The spare wheel is simply listed as "Spare Wheel 18 x 4 Aluminum"
Thanks. The info you posted above was very helpful. I had an '08 CTS that had the tire inflating kit. I went ahead and purchased a spare. When I traded the car for the XTS I removed the spare and ancillary parts and reinstalled the air compressor. I planned on selling the CTS tire and wheel on Craig List and purchasing a spare tire and wheel for the XTS (19"). I just checked the CTS tire and wheel and it is a T135/70R18 104M tire(not sure what the 104M means) and the wheel is labeled aluminum 18 x 4. so it looks like I already have the spare and wheel I had planned on buying. Thanks a lot rayle!.
