Default 18" tyre pressures?

As above. I've just ordered some 18" wheels. What tyre pressures front & rear are people running under normal loads?

Pressures are based on the weight of the car, regardless of wheel/tyre size. You may want to make small adjustments purely on personal preferences if for example a particular tyre has extremely rigid side walls or is very low profiled, or maybe to suit a particular driving style (if you prefer oversteer you could slightly underinflate the fronts to create a little more grip whilst extra pressure in the rears will make them snap loose quicker).

But basically, 32ish all 'round

As Corradoboy said..... I run 32's all round. Don't forget to get your geometry and tracking sorted to get the best out of the new tyres (I'm assuming that you are purchasing new tyres as well as rims).

Thanks. Yeh, I'm getting the Prodrive spring kit fitted aswell as the Prodrive alloys. I'll be wrapping them up in brand new Michelin Pilot Sport 2's. Top Tyre.
Was told by my dealer that it doesn't matter if I change the wheels after the spring kit is fitted (As I'm buying the tyres elsewhere). Would you agree this is OK? I'm sure it must be as you'd have to have the geometry checked every time you had new tyres fitted.

having a geometery set-up takes care of the tracking at the same time right??

You don't need to check the geometry every time you change wheels or tyres, but it may be worth getting someone other than a Subaru dealer to do it in the first place. Many of them aren't very good at it
