Hi,
I have some non-standard wheels/tyres on my Porsche 944 S2 and was looking for advice on how I might determine the correct tyre pressure or where would I find out what tyre pressure I should be using? I have been on Google and searched but with the different sizes on front and back its difficult ...

Any advice appreciated.

The standard Porsche 944 S2 had the following setup,
205 x 55 x 16 on the front with 36 psi
225 x 50 x 16 on the rear with 44 psi

I have
225 x 45 x 17 on the front
and
255 x 40 x 17 on the rear.

I don't know what pressure they should be set at though and they are all set at 32 psi at the minute.

The car is 2998 lbs or 1360 kgs, with petrol, and nearly exactly 50:50 weight distribution.


Best regards,
lmison
