Cadillac CTS Spare Tire Sizes

The Cadillac CTS has used 5x115mm and 5x120mm bolt pattern variations from 2003 to 2019 along with tire diameters ranging from 25.6" to 27.7" 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 CTS years and options. In this case, 165/70R17, 125/70R18, 135/70R18, 145/60R20 and 155/60R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
