The tyre pressures are on the inside of the petrol cap for the original tyres...when you`ve got different wheels and tyres there`s no harm in simply experimenting...add 2psi to the original and see how it feels for your conditions...then another 2psi..and begin to get a feel for what suits you.

I run front 225/50/16 zrn contisport on BBS spider alloys...recommended pressure for the original teledials was 29psi, which I stick to from about now, as the weather is warmer, but add another 3psi in cold weather. At the rear are 245/45/16 contisport on the BBS spider alloys but at 36psi, once again I`ld add about 3psi in winter.

With 17" wheels on a 944 try 32psi front and 34psi rear +/- 2psi depending on how stiff or soft your tyre walls are

It states in the 944 S2 and 944 Turbo drivers manual - tyre pressure front 36 psi and 44 psi rear. Is this correct pressure for my 944 S2 Cab?

It does state those figures from 1990 onwards, up until then the manual stated 36 front and rear.

When I first got my 1990 S2 I followed the book figures and quickly wore out the centre of my rear tyres. 44psi is WAAAAAAY too high in my opinion and we've had lots of discussion that maybe Porsche were covering themselves for possible high speed blowouts for prolonged 150mph cruising on the Autobahn.

Since then I've followed the pre '89 figures of 36 front and rear on 16" wheels and had no problems in over 80k miles and much more even wear (better rear grip too [])

The Porsche figures for 17" wheels on the 968 are 36psi all round.
