Cadillac XT5 Spare Tire

The Cadillac XT5 comes equipped with a compact spare tire stored under the cargo area at the rear end of the vehicle. This temporary spare tire, also known as a "donut," is smaller and lighter than standard tires, making it easier to handle and store. It's designed for emergency use and meant to be driven at lower speeds over short distances, until you get your regular tire repaired or replaced. The standard size for an XT5 spare tire is typically T135/70R18, which could vary slightly depending on the model year. It's important to note that this spare tire is not intended for long-term use like a full-size tire, and the vehicle should be driven with caution while the spare tire is being used.

Cadillac XT5 models manufactured from 2017 to 2025 have tires with overall diameter ranging from 30" 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 XT5 years and trims.

Listed below are compact spare tire sizes that can fit some Cadillac XT5 vehicles based on acceptable tire diameter range of 29.1" to 31.1". Some XT5 models may require the use of a traditional full-size tire as a spare.
