Cadillac XLR Spare Tire

The Cadillac XLR, a luxury sports car manufactured from 2003 to 2009, does not come standard with a spare tire. Instead, the car is equipped with run-flat tires, a technology that allows the tires to function for a limited distance even after a puncture, eliminating the immediate need for a roadside tire change. However, if an XLR owner wishes to have a spare tire, they would need to source one that fits the vehicle's specifications. The standard tire size for a Cadillac XLR is P235/50R18 for the front and P235/50R18 for the rear. Any spare tire would likely need to match or have compatible dimensions and specifications with these sizes, and the driver should be aware that there may not be dedicated storage space for a spare tire in the vehicle. Always consult with a professional or the vehicle's manual for accurate information regarding spare tires.

Cadillac XLR models manufactured from 2004 to 2009 have tires with overall diameter ranging from 27.3" to 27.4", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Cadillac XLR years and trims.

Listed below are compact spare tire sizes that can fit some Cadillac XLR vehicles based on acceptable tire diameter range of 26.5" to 28.2". Some XLR models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Cadillac XLR spare tire size designated by vehicle's manufacturer.
