Guys,

What is the 'ideal' tire pressure to use on a 1973 Charger with modern radial tires? I have the Hayne's manual which lists the factory recommended tire pressures but since tires have changed so much since then, would the ideal pressure change as well?

Car is pretty much stock suspension wise. Only mods are poly bushings, Cooper Cobra tires, and FF stage 3 steering gear. The front end is about 100 lbs lighter than OEM with all the aluminum engine goodies. Would this affect the pressure I need to use or am I over-thinking this?

Thanks!
