oi-punx

I'm running 17" twists (7" front/8.5 rear) on my 951 that were an option on the '99 Boxster. The tires are the stock Pirellis. I was told by the previous owner of these wheels that he was inflating them to a cold pressure of 36 psi. Is this the correct pressure as recommended by Porsche? I'm pretty sure it is, but wanted to check.

Thanks
