What air pressure for 315/35 17 sumitomos?

[gunfish]

I just put on my 17 x 10.5 black bullitts with 315/35 17 Sumitomo HTRZ tires. My car is a 1995 GT Convertible, my daily driver/cruiser, and I'm wondering what air pressure I should run to get the most life out of these tires.
I don't do burnouts, so traction isn't an issue, just want the tires to last me a while.
Any help/advice will be appreciated.

how do you guys like the tires? in the next couple of weeks i'll be buying new wheels and tires and i'm interested in the htrZ's. i'm mainly concerned about dry traction and treadwear and i could careless about wet traction as i live in Phoenix, AZ. so are you guys happy with them?

I have only gone like 2-3k miles but they look like they are holding up. I hear people say they only get 10k miles out of them, don't know how they drive. They will stick, as long as you don't give it too much gas. It is not a drag tire, that is for sure. I can only get like a 2.2 60 foot.

Next, it depends on how these hold up I might go with the gs-d3 goodyears
