Frequently Asked Questions
Common questions about 2020 Audi S4 fitment.
The standard factory tire size for the 2020 Audi S4 is 245/40ZR18. Some trims may offer staggered setups or optional 18-20" wheels, so confirm the trim-specific size shown above.
Typical recommended pressure ranges from 32-36 PSI. Use the door-jamb placard for your trim, wheel size, and load before inflating.
The bolt pattern is 5x112—5 lugs with a 112mm pitch circle diameter. Match this exactly when buying wheels.
Center bore depends on the wheel package. Check the specs above or your wheel’s stamping and use hub-centric rings if needed.
You can typically stay within about +3% overall diameter of 245/40ZR18 to avoid rubbing and speedometer issues. Always account for wheel width and offset, and test clearance at full lock and over bumps.
Follow the manufacturer torque spec (often 80-110 ft-lbs for many passenger vehicles) and re-check after 50-100 miles. Check the manual or dealer if unsure.
