Audi 90 Spare Tire Sizes
The Audi 90 has used a 4x108mm (4 x 4.25") bolt pattern for all models from 1988 to 1995 along with tire diameters ranging from 23.1" to 25.0" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicle applications. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Audi 90 years and options. In this case, 125/70R16, 125/80R17 and 145/70R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
