Well I just got Toyo Proxes T1-S installed today and the guy saids that he put 32psi up front and 35psi in the rear. Is that good for street use. What is the recommended tires pressures for street on 245-35-19/275-30-19.

Can't go wrong following the recommended tire pressure on the sidewall, but it all boils down to suspension mods and how you want the car to perform(i.e. daily stop and go, autocross, freeway-flyer, etc.)
Just remember the lower the tire pressure, the better the grip but greater the heat generated and tire wear.

Toadman is right. Typically it's 1 psi for every 100 lbs a car weighs. So about 31 psi for a 7 after fuel and passengers. Tire size has nothing to do with it.
