Porsche 914 Tyres
- The early 1.7 Porsche 914 fitted a 155R15. In the day it would have been Seperite, Dunlop SP57 155 HR 15 PIRELLI CINTURATO CA67 or 155 HR 15 Michelin XAS FF .
- The majority of Porsche 914 914/6 cars fitted 165R15 tyres. Today the best options are 165 VR 15 PIRELLI CINTURATO CN36 & 165-15 Michelin XAS .
- Some of the 914/6 cars were fitted 14” wheels with a taller tyre side wall to give a fatter more comfortable tyre, in this case we suggest 185 HR 14 Michelin MXV-P as the best option.
- It was also an option to specify wider wheels in the size 185/70 R15. For this size Porsche currently homologate the 185/70 WR 15 PIRELLI CINTURATO CN36 as the best option in this size.
- Pirelli also make a 175/70 WR 15 PIRELLI CINTURATO CN36 which would be another great option for a 914 Porsche.
- Also if you are going to use your Porsche 914 or 914/6 for motorsport, there is an excellent selection of Michelin TB Tyres and the PIRELLI P7 CORSA ™ are also an excellent choice.
- The155 R15, 165 R15, 175/70 R15, and 185/70 R15 tyres mentioned above are best suited to Michelin 15E inner tubes, while the 185 R14 tyres are best fitted with Michelin 14F inner tubes.
It is common practice to want to increase the foot print of a classic cars tyre. When doing so it changes the handling. However if you are keen to increase the size of your Porsche 914/6 tyre or 914 tyre, then sticking with the Pirelli Cinturato CN36 tyre will mean the derogatory side effects will be minimalized, because you will be using a larger tyre that is designed to compliment the chassis of a classic Porsche. You may also be interested in the 215/60 WR 15 PIRELLI CINTURATO CN36 for the rear.

Other Options for Porsche 914 Tyres
There are alternative brands of tyres available for the Porsche 914, but non so well suited. Check out this article done by the German Classic car magazine Autoblid-Klassic. where they compared classic tyres, back to back, for Porsche.
When fitting wider more modern tyres, you will have to start altering the caster and camber angles of the chassis and stiffening the suspension to keep the tyre foot print in contact with the road, or the handling will become more lurid and unpredictable. Which is why you don’t want a modern tyre carcass 185/70R15, 195/65R15 or even wider tyre on the front of your 914 particularly. However if you stick with the rounded period carcass of the 185/70WR15 Pirelli CN36 or Michelin XWX, the handling will be heavier than a 165R15, but still progressive, where a modern carcass will give a more sudden loss of grip.
If you do go down this modified route, for the track the Michelin TB15 range are what Porsche used in the day, and the Pirelli P7 Corsa are also excellent motorsport tyres. There is also a range of Pirelli Cinturato P7 tyres that might be of interest for road use. However it is worth considering that the works you perform modifying you 914 to fit fat tyres will make it an all round less pleasant car to drive on the road. Worth noting that when Porsche fitted 185R14 tyres instead of 165R15. It was as much to get the comfort of the taller side wall as the extra grip of the wider tyre. By the beginning of the 914 Porsche were fitting 185/70VR15 to their 911 and chose not to fit it to the 914 or 914/6 unless you specified it.

914 Porsche History
By the late 1960's, both Volkswagen and Porsche were in need of new models, Porsche was looking for a replacement for their entry-level 912, and Volkswagen wanted a new range-topping sports coupe to replace the Karmann Ghia. At the time, the majority of Volkswagen's developmental work was handled by Porsche, part of a setup that dated back to Porsche's founding. Volkswagen needed to contract out one last project to Porsche to fulfill the contract, and decided to make this that project. Ferdinand Piëch, who was in charge of research and development at Porsche, was put in charge of the 914 project.
Originally intending to sell the vehicle with a flat four-cylinder engine as a Volkswagen and with a flat six-cylinder engine as a Porsche, Porsche decided during development that having Volkswagen and Porsche models sharing the same body would be risky for business in the American market, and convinced Volkswagen to allow them to sell both versions as Porsches in North America.
It appeared to be a perfect win-win situation.
On March 1, 1968, the first 914 prototype was presented. However, development became complicated after the death of Volkswagen's chairman, Heinz Nordhoff, on April 12, 1968. His successor, Kurt Lotz, was not connected with the Porsche dynasty and the verbal agreement between Volkswagen and Porsche fell apart.
In Lotz's opinion, Volkswagen had all rights to the model, and no incentive to share it with Porsche if they would not share in tooling expenses. With this decision, the price and marketing concept for the 914 had failed before production had even begun. As a result, the price of the chassis went up considerably, and the 914/6 ended up costing only a bit less than the 911T, Porsche's next lowest price car. This had a serious effect on sales, and the 914/6 sold quite poorly. In contrast, the much less expensive 914-4 became Porsche's top seller during its model run, outselling the 911 by a wide margin, with over 118,000 units sold worldwide.
