It says on the sidewall of the tire....

With modern cars, the aspect ratio (ratio of sidewall heigh to tyre
width) plays a big part in determining the correct tyre pressures. In
your case, you are moving to an even lower profile (35/40% from
40/45%) and gaining width to maintain the diameter.
Generally, the lower aspect ratio, the higher the recommended tyre
pressure. As such, I would suggest adding 1 or 2 PSI to maintain the
status quo.
However, the whole issue is more complicated that this. The
"recommended" pressure is generally a compromise between comfort, tyre
wear, and performance. The recommended tyre pressures tend to be
favour comfort over performance. The lower the pressure, the greater
the flex in the sidewall. This flex acts as additional suspension,
providing greater comformt and producing less road noise transmission
from the tyres. However, the flexing also causes the tyre to move
around more on the road under heaving g-forces - thus making the car
less accurate to drive, and reducing overall grip.
On my BMW M3 with 245/40/17 rear and 235/45/17 front, I always run
40PSI rear and 36PSI front. This provides me with exellent
performance, but the ride is a little harder and tyres don't quite
last as long. The rears tend to wear out in the middle quicker due to
the slight convexing caused by the tyre pressure.
At the end of the day, it depends on what you want to do with the car.
If you prefer cruising and easy driving, then stick with 35 PSI all
round. If like me, on most days you drive hard enough to slide your
car around, or enjoy very sharp turn in, then run them higher.
Try asking the experts. Bye!

Look on the inside of your car door! There's a sticker and if you look closely, you'll find the recommended tire pressure for THAT car. The tire also states the psi, but remember, different cars have different weights and handling capabilities that affect wear on your tires. So, that's a manufacturer's suggested "general" range. Go by the sticker and if you can't find it or it got scratched off, go to the manufacturer's web site and look it up. Or, call your local dealer and ask the service manager. Hope this helps!

Even the same tire can have different pressures depending their use and way they were manufactured. Suggest always go back to the experts (your Dealer)
