Model: 977 Carrera, Year:2005, Mileage:15,500, Type of use:Street use only
TIRE PRESSURES:I recently purchased new Michelin Pilot Sport PS2 tires for my 2005 911 Carrera Coupe.The Porsche factory Owners manual suggests that the cold tire pressure for 18" wheels be 36 psi in front and 44 psi in the rear.The Michelin ZR 18 tires require max pressure 51psi in front and 50 psi in rear.What is the recommended tire pressure I should use?Thank you.
