    165VR15 XAS

    Longstone Tyres believe that the handling of a car such as a TR6 or Porsche 365 could get any better than it would be fitted with a 165 VR 15 Michelin XAS

    165 VR 15

    The 165R15 Michelin XAS would also be an excellent tyre for Porsche 356, Porsche 901, Porsche 912, and early Porsche 911. TR5 and TR6 had the 165 R15 Michelin XAS offered as an original equipment tyre. They would be perfect for an MGA twin cam, Peugeot 404 and were fitted to the rear of Citroen DS21 and Citroen DS23.

    165 R 380 Michelin XAS

    Back in the day Michelin sometimes called this XAS tyre a 165R380 or 165-380. A Michelin 165 R 380 XAS is simply a Michelin 165 R 15 XAS but with the 15 inch rim size described in millimetres. Triumph at this time realised how much better the XAS was than tyres they previously used. This advert shows the 165x15 XAS on the TR6. It is still the best tyre for the car. Triumph could have fitted wider low profile tyres but they were aware it would spoil the handling and the stuck with 165 R15. Interestingly around the same period they took the Triumph Stag off 185 x 14 tyres and fitted 175 x 14 Michelin XAS, lowering the tyre size. Many Triumphs are over tyred. Longstone Recommend sticking to a 165 x 15. The Overall Diameter of the 165 VR 15 Michelin XAS is 646 mm and the width is 167 mm.

    The 165HR15 CINTURATO ™ CA67 has been reproduced in November 2014 by PIRELLI. 165HR15 is a very important tyre size for a wide range of classic cars. Cars such as the Volvo P1800, VW Beetle, TR4, Daimler Dart, Porsche 356 and 911, etc, etc, would have fitted a 165HR15. This is the first time for some years there has been a genuine period tyre in the size 165HR15 available for pre 1965 cars.

    165HR15 Tires

    Many cars that fitted cross ply (bias ply) tires in the size 5.60-15 or 5.90H15 may well want to fit a radial 165HR15 tire to improve a cars directional stability, in which case PIRELLI's 1952 CINTURATO ™ CA67 165HR15 is the ideal tire.

    185/70WR15 Tires

    185/70vr15
    In 1968 when the development of low profile tire technology hit the road PIRELLI were at the for front with this 185/70WR15 CINTURATO ™ CN36. The rounded carcass gave progressive steering which is critical to cars of this period, and they cannot be replace by modern tyres without spoiling these handling of these cars. It is worth pointing out that although the tyre size 185/70WR15 was not original equipment on many cars, a 185/70WR15 tire is a low profile alternative to a tire of the size 165R15, which is why this PIRELLI 185/70WR15 CINTURATO ™ CN36 is a great choice for people that want to put a bigger tyre on their TR4, TR5, TR6, Volvo P1800, MGC, Austin Healey 100/4, Austin Healey 100/6 and Austin Healey 3000

    185/70WR15 Early Porsche tires

    It is fair to say that the size 185/70WR15 is predominantly associated with the early Porsche 911 as this tyre was original equipment on a 911 from 1969 when the CN36 first came out right through till 1986 when they went slightly larger on the front, having of course adjusted the car to suit more modern tyre carcasses. There has been some extensive testing of what tyres suit the early 911 best and the German article below proves categorically that the CN36 CINTURATO ™ is the one, this is backed up by Porsche awarding these tyres the N4 Porsche homologation. In 1972 Porsche fitted wider rims to it's Carrera and RS models and they fitted a 215/60WR15 PIRELLI CINTURATO ™ CN36 as a rear tire. This tire is also currently being produced by PIRELLI and is homologated with the N4. As time went by the 911 fitted the larger tyres across the range right into the 911 SC models it was fitting 185/70R15 CN36 on the front and 215/60R15 CINTURATO ™ CN36 on the rear. This page shows you a fitment guide for Classic Porsche tyres.
    Although not a great deal of cars actually fitted the tyre size 185/70x15 and standard equipment, many cars such as Volvo P1800, Triumph TR6 Porsche 912 for instance that would have originally fitted the tyre size 165R15 might want to fit a more modern up to date low profile tyre, and a 185/70R15 would have the same overall diameter while offering a wider section. Under these circumstances PIRELLI's CINTURATO ™ CN36 would be an excellent choice, because although it is a wider tyre it is designed with these sorts of cars in mind. Where a more modern tyre of the size 185/70R15 would have a very different carcasse, designed to be used in different circumstances.

    The Overall Diameter of the 185/70 WR 15 PIRELLI CINTURATO ™ CN36 N4 is 632 mm and the width is 183 mm. For more information on the 185/70 WR 15 PIRELLI CINTURATO ™ CN36 N4 please see below or call +44 (0) 1302 711 123.

    Although the tyre size 205/50 YR 15 is a current and very common tyre size that was fitted to cars like a VW Golf from the end of the '90s to a Mazda2 of the 2010s. There is something special about a 205/50 YR 15 PIRELLI CINTURATO ™ P7 of the '70s. The P7 is such an evocative tread pattern that carried on through to the '80s and was the tyre of choice for so many sports car users.


    205/50 YR 15 tyres

    When the Lamborghini Countach started to fit 205/50YR15 CINTURATO ™ P7 tyres on the front in the '70s it was the beginning of a new era of ultra low profile tyres.

    Today this 205/50YR15 P7 CINTURATO ™ is part of the beginning of a small range of P7 tyres very much aimed at satisfying the needs of Classic Porsche owners, this P7 is matched to a rear tyre 225/50YR15 CINTURATO ™ P7 which were fitted to the Porsche 930 3.0 Turbo and 930 3.0 Carrera.

    185/70VR15 Michelin XWX was original equipment on the Porsche 911, Porsche 924, and the front of a De Tomaso Pantera and Maserati Merak. This is an extremely high quality performance tyre.
    185/70R15 is a later low profile equivalent to a 165R15. It is often fitted to cars like Austin Healey, Triumph TR4, TR4 A, TR5, TR6, MGA, VW Beetle. Because the Michelin XWX is such an exceptional tyre it was the tyre of choice in the 70's and still offers excellent handling, especially if you are fitting the size 185/70-15 to a car that should have 165R15.

Classic 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 which came out in the ‘50s or the 165HR15 Michelin XAS Which came out in 1965. Both brands are excellent period tyres, made by two of the world's best tyre manufacturers to the highest standards, they will give perfect handling characteristics while also being genuine original equipment..

Porsche themselves have now become involved in sourcing classic tyres for their historic 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 165 VR 15 PIRELLI CINTURATO ™ CN36 N4. Having the V speed rating is great and appropriate to these early 911 cars. Although the CN36 tread pattern did not come about until 1968, by which time the 911 was fitting a 185/70VR15.

Interestingly Porsche widened their rims from the 4.5” Fuch alloy to a 5.5” Fuch alloy in 1967, but they continued to fit 165R15 tyres. These wider rims gave greater directional stability. It wasn’t until a year later in 1968 where Porsche moved onto fitting 185/70VR15 tyres front and rear. In the day the 185/70WR15 Pirelli Cinturato CN36 or 185/70VR15 Michelin XWX were the best of the OE tyres, and we would suggest today if you have a late ‘60s or ‘70s cars then they would still be the best tyres for an early 911 today.

Initially fitted all round; I85/70VR15 tyres were the mainstay tyre for the 911 right through to the 911 SC until August 1986 where they changed the front tyre to a 195/65R15. However over nearly 2 decades there had been a variety of changes made to the cars geometry that makes a 911 more suited to the modern tyre carcass of a 65% profile tyre on the front axle.

In 1972 on the 911 Carrera and RS models Porsche fitted a wider rear wheel and fitted 185/70WR15 Pirelli Cinturato CN36 on the front and 215/60WR15 Cinturato CN36 on the rear. We are fortunate, to be able to provide these tyres again made by Pirelli with the N4 Porsche homologation. As the years went by the various models of 911, moved over to fitting a wider rear wheel. Even with later 1980s cars like the 911SC they were still fitting 185/70VR15 on the front and 215/60VR15 on the rear. We would suggest that the Cinturato CN36 N4 tyres are the best.

We have information on Porsche 930 Fitment here.

Some of the performance Carrera, Turbo and RS models fitted some extra wide wheels which they tended to fit Pirelli Cinturato P7 Tyres to which Pirelli are producing again today in the sizes 205/50R15 P7, 225/50R15 P7, 285/40R15 P7 & 345/35R15 P7

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.

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 of road legal rally tyres for wider wheels, offering options up to 13" wide wheels. There is 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.

Pirelli’s commitment to these fabulous early high performance 911 Turbo’s, Carrera, RS, RSR etc are also backed up by their range of Pirelli Cinturato P7 tyres. In the Mid ‘70s when the 930 came out they were fitted with 205/50R15 Cinturato P7 on the front & 225/50R15 Cinturato P7 on the rear. Some of the RSR cars had 11” wheels with 285/40R15 Cinturato P7 tyres on the rear and 9” wheels with 225/50R15 Cinturato P7 on the front, all of which fortunately are being made again by Pirelli.

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 definitely not a car for the mainstream. The 911 driver of the time wanted fast thrills with no frills!

The earliest 911's were built from 1965 to 1969 and were short wheel base models many 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 911's 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........
