Cadillac ATS Spare Tire Sizes

The Cadillac ATS has used a 5x115mm bolt pattern for all models from 2013 to 2019 along with tire diameters ranging from 25.0" to 25.2" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Cadillac ATS years and options. In this case, a 125/70R18 temporary spare tire is the recommendation for all applications.
