Early 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.|
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. then 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 911s.|
Porsche 911 SC Tyres
Later Porsche moved the 911 on to the SC models. The 911SC continued to fit 185/70WR15 PIRELLI CINTURATO ™ CN36 N4 on the front and 215/60WR15 PIRELLI CINTURATO ™ CN36 N4 until August 1986, when they moved the front tyres onto 195/65R15 as a standard equipment tyre. Some of the sports models of this period such as the 3.0 Turbo, 930, 3.0 Carrera, would want to fit more modern lower profile tyres 205/50ZR15 CINTURATO ™ P7 N4 on the front and 225/50ZR15 CINTURATO ™ P7 N4 on the rear. These tyres have also attained Porsche homolgation. From 1985 you could specify the 16" wheels for your 911, for which Michelin make their 205/55ZR16 SX MXX3 N2 & 245/45ZR16 SX MXX3 N2 and these tyres were fitted to the 930 Turbo and Carrera versions of Porsches 911

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........
