Tyre air pressure

[wanda]

What is the needed tyre pressure for 205/50/17". The book says 36 psi for the front and 32 psi for the rear, but I get the feeling you can do more.

Why would you or anyone want to increase this pressure? Unless you want to make the ride too hard

same question to those running 215/35/19's.

I put 36 in the fronts and 31 in the rear, but the fronts always looks flat... (ok i know there is much side wall, but bear with me :P)

Any advise as the roadnoise is loud.
