Cadillac STS Spare Tires
The Cadillac STS used a 5x115 mm bolt pattern for all models from 2005 to 2011 along with tire diameters ranging from 26.0" to 27.3" tall. Using a temporary compact 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.
The tire diameter and the wheel diameter clearance have been taken into account for the specific Cadillac STS years and options. In this case, 125/80R18, 145/80R17 and 145/60R20 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters. We've provided a breakdown by vehicle generation and model specifics to help you find the correct Cadillac STS spare tire.
