have quick read of this
Tire Tech Information - Air Pressure/Load Adjustment for High Speed Driving
as long as you dont go under the oem psi or over the tire psi rating pick a psi that you feel balances comfort/handling.

For example on a X308, "by the book" would mean 42 psi on any brand tire other than the original factory issue Pirelli P-Zero. Clearly ridiculous, but "by the book".
As a matter of fact, going "by the book", the only allowable replacement tire is the factory issue Pirelli P-Zero.
Even, "the book" gives a range of inflation pressures depending on intended usage.
"the book" is a safe answer for the casual driver with no desire to look further ... it is not always the optimal answer.
If it were the fountain of all knowledge, there would be no need for places like JF.

I had so many problems with getting the right tire pressure on my XK8. It seemed I was replacing my tires because of center tire wear (over inflated) until I found the right pressure. However, on my S-Type I found the 32 – 34 works well. I now have 40,000mi on my tires and if it were not for a bad ball and 2 worn bushings on one side I would be getting at least another 15,000 on them. My driving has been 80% highway and 20% town. As others have suggested use the 32 – 34 psi it seems to be the right formula.

34/36 is reasonable - but I would advise against it as Gus pointed out above. Stick with 32 psi in front and 34 psi in the rear and check cold tire pressures weekly to obtain maximum usage on tires. Also, rotate every 6K miles...
