3 The longevity of Michelin’s endurance racing tires has increased by a factor of three since 1998

11 The number of sets of Michelin tires used by the winning #1 Audi in 2012

35% The additional distance that Michelin tires are capable of covering compared with 10 years ago

5 The number of stints covered on the same set of Michelin tires by the Signature LMP1 prototype in 2009, as well as by Audi Sport Team Joest’s Audi R18 TDI ultra in 2011 (almost four hours’ racing)

Less than 6,000 The number of Michelin tires available for the 2013 Le Mans 24 Hours, compared with 9,000 tires four years ago

1,231km The distance covered by the same set of Michelin rain tires on a LM GT1 car in 2008 (87 laps)

6,500 The number of times each tire is compressed every lap. That’s 84,500 compressions per 13-lap stint

120 The number of times its own weight an endurance racing tyre is capable of withstanding. That’s the equivalent of a person who weighs 75kg supporting a load of nine tons!

Approximately 100°C The ideal working temperature of a slick racing tire

150 The number of different ingredients that go into a racing tire

12.7kg The weight of a rear Michelin tire (37/71-18) for an LMP1 prototype (without wheel). The narrower Michelin tires (31/71-18) that the LMP1 cars will use in 2014 will weigh 11.5kg

36 The number of cars racing on Michelin tires at Le Mans in 2013

3g The lateral force to which tires are exposed through the Porsche Curves

3.5g The longitudinal force generated under braking at the end of the Mulsanne Straight

More than 30 The number of times the tire of an LMP1 car rotates every second round Le Mans
