Porsche 911

Initially the Porsche 911 would have fitted 165HR15 PIRELLI CINTURATO ™ CA67 or 165HR15 Michelin XAS. There is also now a 165HR15 PIRELLI CINTURATO ™ CN36 N4 homologated by Porsche for the early 911. In 1968 they moved onto fitting either 185/70VR15 Michelin XWX or 185/70VR15 CINTURATO ™ CN36 N4. Then from 1973 starting with the sports models such as the 911 Carrera or RS had wider wire wheels with 215/60VR15 CINTURATO ™ CN36 N4 on the rear. Again these CN36 tires have the N4 homologation from Porsche recommending them for the 911.
