What is the recommended tire pressure for Nokian WR 235/45/17 tires on Audi S4 Cabriolet?

My first reaction to driving with these tires is there no significant loss of ride and handling, but a big increase in noise. I am hoping that the noise will decrease with age as I have only put a few hundred miles on them. They handled well in dry, wet, and icy roads so far, but in my cabriolet, I heard the tire noise much more than the summer tires. I am wondering if the tire pressure can be adjusted to reduce the noise without losing handling/ride.

I'd say keep at stock, but Jprice may have more insight on psi on the Nokians?

I have exact same size WRs; they are very quiet. Something's wrong in your set up.

What set-up problems could cause noise?

Going from all seasons to WRs on my wife's car she commented there seemed to be more wind and engine noise.. but it was just that there was less tire noise in comparison.

Gary is correct, they should be run at the recommended pressures for your car.

Gary is correct.. what is the recommended pressure for 17s on an S4 Cab anyway?

A bearing shouldn't go bad that quickly (if you noticed the difference right away when you had the WRs installed).. unless the car got smacked up against a curb or something. If the car is misaligned, it can cause noise, same if the wheels are not balanced correctly (but then you should also feel some vibration as well)

It's also possible that one of the tires you got has a manufacturing defect.

Oh, also if for some reason one of the tires got mounted backwards (or if the wheels got rotated in an X pattern instead of front to back only on same side), that could cause extra noise as well. There are direction indicators on the sidewall of the tires that indicate which way it should be spinning when the car is moving forward.

I can't remember if you live in mpls or not.. if you do, I'd be happy to take a listen as well.
