Cadillac XT4 Spare Tire

The Cadillac XT4 does not come standard with a spare tire. Rather, it is equipped with run-flat tires that allow the vehicle to continue to drive, at a limited speed and distance, when they are flat. This sleek SUV design features an optional Compact Spare Tire (RJA), a T135/70R18 blackwall which is a little smaller in size and lighter in weight than regular tires. If you prefer to have a spare tire, Cadillac does offer a spare tire kit for this model at an additional cost. Depending on the trim level, the kit may come complete with a jack and tools necessary to change the tire. It should be noted that cargo space may be affected by the addition of the spare tire as it requires a specific storage area within the vehicle.

Cadillac XT4 models manufactured from 2019 to 2025 have tires with overall diameter ranging from 28.7" to 29.1", 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 XT4 years and trims.

Listed below are compact spare tire sizes that can fit some Cadillac XT4 vehicles based on acceptable tire diameter range of 27.8" to 30". Some XT4 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 XT4 spare tire size designated by vehicle's manufacturer.
