Tyres

Hey guys...need some advice on tyre pressures...i keep getting different opinions everytime i get them checked..i've got some 205/40 on a 17" how much pressure should be in them anyway?...oh and my front rethreads are peeling at the sides...not too serious and they've stayed that way for a while...any chance something really bad might happen?

The pressure should be on your car. Open your door and you'll see a white baseball card - sized sticker. I think the fronts are 30psi and rears are 29psi.
