I run a 1.4TFSi. I ordered 18" RS4 style wheels with the car. When I looked at the fuel filler cap it only gave pressure levels for 16" and 17" wheels. I am currently running 35 bar all round.
Normally the car only ever carries myself, my wife and some light baggage. Does anybody have any idea what the correct tyre pressure for this car with 18" wheels is? If you don't have a 1.4TFSi what tyre pressure do you use in your A3 with 18"s?
