Cadillac SRX Spare Tire

The Cadillac SRX does not come equipped with a traditional spare tire. Instead, it originates with a tire inflation kit that serves as a temporary solution in the case of a flat tire. This kit contains a sealant that can plug small punctures, and a compressor to re-inflate the tire, allowing the driver to reach a service station. However, some owners prefer to purchase a full-size or compact spare tire separately for added peace of mind. The exact size of a spare tire for a Cadillac SRX can vary based on the model year, but typically falls within the range of P235/65R18 for full-size spare tires. The compact or "donut" spare tire is usually sized at T145/70R17. Owners should check their specific model's manual to confirm the correct tire size.

Cadillac SRX models manufactured from 2004 to 2016 have tires with overall diameter ranging from 29.1" to 30.2", 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 SRX years and trims.

Listed below are compact spare tire sizes that can fit some Cadillac SRX vehicles based on acceptable tire diameter range of 28.2" to 31.1". Some SRX 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 SRX spare tire size designated by vehicle's manufacturer.
