Tyre Pressures

Hi all.

Although I've been a Porsche club member for several years, this is my first post to the forums. Glancing through the previous posts, I'm now wondering why I've not done so before. I am sure that I would resolved far more easily some of the issues I've had in the past.

Anyway, that aside, I am afraid that my first question is very basic.

I own and enjoy when I can a late-1988 944S. It is been off the road during the winter but, with the odd sunny day appearing, I am starting to prepare it for use again.

However, following a recent house move, I can't at present find my manual for the car.

Can one of you be good enough to let me know what the correct front and rear tyre pressures should be for this model?

The tyres fitted currently are Pirelli P6000 215/60 R15 94W.

Thanks,

Andy.
 
I used to run my Lux with 29F/36R, as in the handbook, or a little less in the rears. Same tyre size, so I'd think the "S" would be the same.
 
Thanks to you both for your replies. You are quite right, madrob6. The tyre pressures (29F/36R as Paul said) are shown on a label on the inside of the fuel flap. It's hard to believe that I could have owned this car for the best part of 4 years without knowing that. I can only think that my attention would have been on the amount to pay shown on the petrol pump instead! Thanks again, Andy
 
Take the 'recommended' values as a guide only, and play around with them from there. I run slightly higher pressure than recommended in the tyres on my S2, and find that it improves things a LOT. (944's are quite tyre pressure sensitive when correctly set up.) Oli.
 
Checked the fuel filler flap earlier and it says 36 front and 44 rear for the S.2. Seems high for the rears - I currently run 36 all round, but am going to try 40 to see if that smooths the potholes any better [:D]
 
I don't think that upping the pressure will smooth out the potholes better the government spent the road tax money on the roads

That's what the book says. Sounds very high to me, possibly ok on smooth autobahns but not our tarmac. [&:]
 
ORIGINAL: sc0tty Spill the beans please Oli, what PSI are you running? [:)]

From memory, 38psi all 'round. I know that the 'recommended' pressures changed from model year to model year, despite the wheels and tyres (and indeed the rest of the car) being the same. I think they are 'recommended' to be at 36psi all 'round on mine ('89 S2), but it responds better to a bit more poundage. Oli.
 
The 1990 onward manuals say 44psi in the rear [:eek:] If you pump up to that figure you will notice a very skittish rear end and your tyres will wear out in the middle. The 1989 manual says 36psi all round which is a much better figure in my experience. 944 Register folklore has had many theories about that 44psi figure over the years and the most plausible seems it was amended by Porsche to counteract high speed blow outs on the German Autobahns where this car can sit at 150mph all day long (until the tyres pop - eek! )
