The Bugatti Veyron crossed the 400 km / h barrier 15 years ago. Bugatti Chiron a year ago “crossed” the border of 300 miles per hour, that is, 482.7 km / h. Now the SSC Tuatara has driven faster than 530 km / h. Each of these records has one thing in common – all these cars raced on Michelin tires. Cars of this brand will gladly be accepted for recycling under the program scrap cars for cash.

Breaking speed records is like an ongoing process that, by the way, stimulates technological developments in the automotive industry. Manufacturers are improving the performance of powertrains, refining aerodynamics and suspension, and inventing solutions that allow you to squeeze even more and move even faster. All of this, however, is useless when the correct tires are not available.

When the Bugatti Veyron debuted a few years ago, everyone was shocked by the 1001 horsepower. Today’s cars have twice the power of their powertrains, but what top speed they can go – not in theory, but on asphalt – largely depends on the tires. The tires of a car moving at a speed of 400 or 500 km / h must withstand incredibly high overloads, of the order of several thousand “g”, while maintaining structural strength in the presence of centrifugal force, which wants to break the rubber into shreds, and at the same time remove heat collecting, accumulated heat , which in the shortest possible time can disassemble the tire and lead to its explosion. Space technology is needed here, literally.

Specifically for the Chiron, for example, reinforced tires have been developed based on the production Michelin Pilot Sport Cup 2. The BG mark indicates that they have been strictly adapted to the performance of this heavy 1.9 ton supercar. But to do this, Michelin engineers had to turn to the aforementioned space technology. After all, it was the French brand that supplied the tires for the Atlantis space shuttle at one time, and tires are no bigger problem than extreme temperatures in low-earth orbit and the safe landing of a heavy spacecraft.

When developing Michelin Pilot Sport Cup 2 tires, the specialists of the French manufacturer used their technology centers in French Ladoux and American Charlotte. Extreme tests were carried out using specialized equipment that had to find the limits of the capabilities of these tires before they were used in an actual attempt to break the speed record. We add that compared to the factory Michelin Pilot Sport Cup 2 tires, those designed for the Bugatti Chirona received a carbon fiber reinforcement of the carcass.

A few months ago, when Shelby Super Cars began testing its SSC Tuatara, a 1,750-horsepower car, it was decided to return to Michelin Pilot Sport Cup 2 tires. As it turned out, they used factory tires for this, without carbon reinforcement. Earlier tests were carried out that confirmed its endurance at high speeds, and this, in turn, paved the way for an attempt to set a new record.

The SSC Tuatara was tested on the same stretch of road where the 2017 Koenigsegg Agera RS – also on production Michelin Pilot Sport Cup 2 tires – reached a record 477 km / h and, incidentally, achieved several other outstanding results. Weighing just over 1.2 tons, the SSC Tuatara traveled in two directions, of which the average speed was up to 508.73 km / h, and in one direction it was even 532.93 km / h. No other road car has gone even faster, and the Michelin Pilot Sport Cup 2 tire limit seems to be unlimited …
