Michelin Pilote X
Michelin developed their 600WR16 Pilote X to be the tire to stand up to the test of the high speeds of the W Speed Rating capability (168mph/270Kmh) that could be reached by the Jaguar XK 150 or the Aston Martin DB. It became apparent to Michelin that many of the classic sports cars of the 50's were capable of incredible speeds when compared to the capabilities of the tires at the time. These classic cars when now driven on modern roads would be able to maintain these high speeds, thus the Pilote X was developed.
Michelin Pilote X: Englebert
In the 40's and 50's Englebert were the racing tires of choice for manufacturers such as Maserati with their 250F, Lancia with the D50 and many of the Ferrari's of the day would race on Englebert tires. At the end of the last century Michelin reintroduced the range of Englebert racing tires which have since been discontinued. However The 600WR16 Pilote X looks very reminiscent of the Englebert racing tire.
