Porsche 911 Tyres
Porsche 911 tyres for a standard car as recommended by Longstone Tyres
Early Porsche 911 originally fitted a 165R15 tyres. They fitted a variety of different brands of tyres, including Michelin and PIRELLI CINTURATO ™. Currently Longstone tyres would suggest that the best tyres for these pre 1968 early 911 cars would be either the 165HR15 PIRELLI CINTURATO ™ CA67 or the 165HR15 Michelin XAS.
Both brands are excellent period tyres, made by two of the world's best tyre manufacturers. Porsche themselves have become involved in sourcing classic tyres for their cars, and giving them their seal of approval, in the form of a "N4" marking, meaning they have a Porsches Homologation. In doing so they have made a 165VR15 PIRELLI CINTURATO ™ CN36 N4. Having the V speed rating is great and appropriate to these early 911 cars, however sadly the CN36 tread pattern did not come about until 1969, by which time the 911 was fitting a 185/70VR15, however the CN36 tyres are excellent, look great, will handle excellently and of course have Porsches seal of approval as suited to these early 911's.
Porsche 911 Tyres
|In 1968 Porsche fitted wider rims to its early 911 cars and changed the tyre size to 185/70VR15. We believe that the earliest cars were offered with either Continental, Dunlop or Michelin XWX. In 1969 PIRELLI developed their low profile tyre developed in conjunction with Porsche, the CINTURATO ™ CN36 which became the tyre of choice on these early 911's.|
Porsche have recently been involved with PIRELLI producing and homologating the 185/70WR15 PIRELLI CINTURATO ™ CN36 N4, which would be the tyre of choice along with the other original tyre the 185/70VR15 Michelin XWX. In 1972 with the 911 Carrera, Porsche started to fit a larger rear wheel with the tyre size 215/60R15. Fortunately in conjunction with Porsche, PIRELLI produce the tyre 215/60WR15 CINTURATO ™ CN36 N4, homologated by Porsche for their top of the range early 911, such as the Carrera, RS, 911S, 911 Targa & Turbo models.
Racing 911 Tyres
If you are wanting to take your car on the track there are a wide range of options available. Dunlop Racing and Avon CR6ZZ for the early 911 and Michelin's extraordinary TB range for wider wheels, offering options up to 13" in the full tread Michelin TB15, and the semi slick Michelin TB5 F & R with it's choice of front and rear compounds, and the full wet Michelin PB20.
|When the first Porsche 911 came on to the market sporting a 2-litre 130bhp engine, they were up against some extremely good sports cars. Aston Martin DB6, E-type Jaguar and Ferrari 275 GTB were just a few of these cars. The first Porsche 911 it has to be said was up against it, and was definitely not a car for the mainstream. The 911 driver of the time wanted fast thrills with no frills!|
The earliest 911s were built from 1965 to 1969 and were short wheel base models most of which are now seen thrashing around in all their glory at historic race and rally events. These particular cars tend to be the most desirable amongst the for mentioned group of petrol heads. The next of the Porsche 911s were built between 1970 and 1973 with engines ranging from 2.2 - 2.4 litres. These cars were followed shortly by the arrival of the impact bumper model in 1974, with the top model sporting a 3.2 engine and given a Carerra badge.
Another of the Porsche range was the 2.7 R.S, which was brought out between 1972 & 1973. The Porsche 911 2.7 R.S (R.S standing for Rennsport meaning motorsport/circuit racing in German) sported wide arches and wheels, lighter body work, stiffer suspension and of course a powerful 2.7 engine. This car would prove to be the start of the R.S series and what was to be, a successful racing pedigree.
Shortly after the Porsche 911 R.S.R 3-litre and Carrera R.S.R Turbo were produced, though only in small numbers, making them eligible for racing. Porsche had almost immediate success with one of their Carrera R.S.R Turbos finishing 2nd at the Le Mans 24 hour race in 1974. The engine used in the Carrera R.S.R Turbo would go on to form the basis from which Porsche would make many assaults on the world of motor sport racing and not only that but also the start of Porsche fitting turbos to their cars.
In 1974 Porsche decided to up the engine capacity from 2.7 litres to 3.0 litres for the R.S using a k-jetronic Bosch fuel injection system giving the Porsche 911 3 litre R.S almost twice as much power as the 2.7 R.S. With this extra power came more racing capability........
