Audi S3 Spare Tire Sizes

The Audi S3 has used a 5x112mm bolt pattern for all models from 2015 to 2023 along with tire diameters ranging from 25.1" to 25.5" 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 Audi S3 years and options. In this case, 125/80R17 and 125/70R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
