the reason i'm sceptical is that my dad's porsche the rear tyres are 265/35, so thats 91mm profile, mine are 205/40 so mine are 82mm profile.
The reccomended pressure for his tyres are 45psi in the rear

if u go to an air machine there is usually a chart on the wall with recommended tyre pressures look for somethin close to ure tyre size and car model.
whenever i do mine i just put anything between 28 and 30 all round and thats with 215/35/18

Chris 44psi is the max tyre pressure the tyre can take. 
Red - I am running 32 psi all round as recommended when I got the alloys

omg, THE TYRE PRESSURE SHOULD BE THE SAME AS THE STANDARD TYRE PRESSURE, u cant ask people of here cos it depends what sort of driving you do etc.. refere to ure drivers manual which will give you the correct pressure for your sort of driving and load in the car. its the same no matter wat tyres u have.

Yes for a Corsa B, 35 on the front and 29 on the back seems best.

having a slightly lower pressure on the back helps the back end grip better in the wet. More tyre on the road. Having higher pressure on front is a must because of the engine weight and braking forces.
