i have a 1956 porsche 356 A i use 165\ 80\ 15 radial tyres i would like to know what pressure is ideal for my car

Start with 25 front and 30 rear and go from there. Keep at least 3 to 5 psi difference front to rear. Do not go over 30 or the car will ride like a tennis ball. Very bouncy and harsh. Different makes of tire will perform differently and different drivers like lower or higher pressures, also depends on driving style. Higher pressures for driving fast on curvy roads.

+1 what David said using stock size 165-15 tires. I'm using 24# frnt- 29# rear with Vredestein Sport Classic tires.
