Tires

two questions?
i just change my run flats to non run flat, are the tire pressure remaining the same 36psi front/39psi rear

tires size are 225/40/r18 255/35/r18 rear

im interested in filling my tires with nitrogen. anybody ever got it done? is it worth the money, also i read it improves the ride quality
