Classic Porsche Tyres
In the world of modern tyres it is common place to come across a tyre test. However in the world of classic tyres the investment never seems to be there to do a proper modern tyre test. However a German magazine in July 2016 conducted this modern tyre test on classic Porsche tyres. This classic Porsche tyre test has been translated from German to English. What is remarkable in this tyre test is quite how well the PIRELLI CINTURATO ™ CN36 classic Porsche tyres performed in the table at the end. The scores in this table are not scored in relationship to the other tyres in the test, so when a score of 1 is recorded, then that is a perfect score for a classic tyre or a modern tyre. It is wonderful to see that these classic Porsche tyres can give such exemplary results.
The simple time honoured shape of a Porsche 911 has been something that has inspired classic car enthusiasts for years. The refined elegant pure shape is unmistakeable. Now Longstone tyres, with the support from the world's best tyre manufacturers are able to supply tyres for classic 911's.
