Tyre Pressures

[Waylander]

Same size on my 968 but I think the car is a bit heavier 36 all round is the norm, but I like it just a little softer 34

Just out of interest what pressure should I be running my tyres at ? I am running 17 inch cup 1'a with 225 50 17 on the front and 255 45 17 on the back. I just put them at 35 psi but i'm not sure it's right.

Opinions please

Softer still, 32 all round.

Same tyre sizes here - 34psi hot. Running grippy track tyres I find anything softer than 32 has too much sidewall roll.

As Scott says, I run my 16"s now the same as I used to run the 18"s - 32psi all round

General advice: I find that if you look at the sidewall of the tyre and find out the maximum pressure for it, and inflate it to 90% of that figure, it's likely to work well. Try 1 or 2 PSI each side of this if you want to vary it. Oli.

mine say max 60 PSI really 90% of that???

Crumbs - what tyres are they? Try it. Aim for 54 (purely as an experiment) and see how you get on. The rule works for most instances and I'd be curious whether it works for something with such a high rated pressure. Oli.
