Porsche 911 Tires

This shows Porsche fitment in 1969. the new low profile tyres are so new it seems they have given the wrong description to the 911S tires, they should be 185/70VR15

Early Porsche 911 tires

When the first Porsche 911 cars evolved from the 356 they maintained the same tire size 165HR15. One of the original equipment 165HR15 tires that was offered by Porsche with the early 911 was a Pirelli 165HR15. Today Pirelli produce the 165HR15 Pirelli Cinturato CA67 which is a perfect tire for an early 911, or for that matter a 912 or 356. In 1968 Pirelli developed the CN36 tire, Pirelli also now make a 165/80VR15 Cinturato CN36. This is N homologated by Porsche themselves as the perfect V speed rated tires for their early 911.

Classic Porsche 911 tires

At the end of the 60's low profile tires were developed, and of course Porsche, being the company they were, embraced this modern technology with the 911. The low profile alternative to the 911's original 165HR15 was a 185/70VR15. Again Pirelli were chosen as one of the original tires on these classic Porsche 911's, fitting the 185/70VR15 Cinturato CN36 HS that are still produced today by Pirelli, very much with the classic 911 in mind.

911 2.7 Carrera RS Tires

When Porsche developed the 911 Carrera and 911 RS models with the 2.7 engine in 1973, they needed a wider rear tire. They continued to fit the 185/70VR15 CN36 on the front and then on the rear they fitted 215/60VR15 Cinturato CN36 on the RS and Carrera models. Through out the 1970s the various models of Porsche 911 moved over to fitting the wider 215/60VR15 CN36 tires on the rear, right through to the early 911SC models.

Porsche 930 Tires

The early Porsche 930 3.0 Carrera & 930 Turbo cars fitted 205/50R15 P7 on the front and 225/50R15 P7 on the rear. Then the later 930 Turbo & the 930 Carerra “Turbo Look“ Porsche moved to 16” wheels and fitted 205/55R16 P7 and 225/50R16 P7 on the rear between 1978 and 1985. Then in 1985 they increased the 930's rear wheels and tires to 245/45R16 P7.

Porsche 911 SC Tires

The early 911 SC  still fitted the 185/70VR15 & 215/60VR15 tires for which  we would suggest the Pirelli CN36. Then in 1986 along with some other setup changes the 911 SC moved onto a 195/65R15 front tire. However from 1985, Porsche were offering 16" wheels on these cars and fitting 205/55R16 Pirelli P7 and 225/50R16 Pirelli P7 on the rear.
