Goodyear Racing Truck Tires break FIA World Speed Records
Smolensk Russia, July 30, 2012 – Jochen Hahn in the Castrol Team Hahn Racing, driving his MAN truck racing on Goodyear tires still leads the FIA European Truck Race Championship after the seventh round, which took place at Smolensk, Russia on July 28 and 29. On the Saturday, the first race was won by Antonio Albacete in the team Equipo Cepsa driving an MAN and the second race was won by Rene Reinert also driving an MAN. On Sunday Jochen Hahn won both the first and the second race. The next event will take place at Most in the Czech Republic on September 1 and 2 after the traditional August break.
Goodyear Truck Racing tires, as used by all competitors racing in the championship, were fitted to the truck that has just been confirmed as having broken two world speed records.
Mean Green, the world’s fastest hybrid truck, broke the records in April at Wendover airfield in Utah, USA. The Volvo-built truck, which is owned and driven by Boije Ovebrink, broke international speed records for the standing kilometer (two-thirds mile), a record already held by the hybrid truck, and the flying kilometer1.
The confirmed results2
- Standing Kilometer – 153.252 km/h (95.245 mph) (previously 152.253 km/h (94.605 mph))
- Flying Kilometer –236.577 km/h (147.002 mph) (previously 218.780 km/h (135.943 mph))
Goodyear worked closely with Volvo developing the tires for Mean Green, which pumps out a massive 2,100 horsepower (1,566 kW) and nearly 5,000 lb-ft. (6,770 Nm) torque, and accelerates from zero to 100 km/h in four seconds.
The 315/70R22.5 Goodyear Truck Racing tires fitted to the steer axle were the same as those used in the FIA European Truck Racing Championship. For the drive axle, Goodyear specially built 495/45R22.5 single mounted tires. These were developed on the carcass of the 495/45R22.5 Goodyear Marathon LHD tire demonstrating the incredible strength of these tires. The components of the carcass including the compounds and reinforcements were the same as on the standard tire and the tire was optimized with regard to high speed durability and performance. This included a sub-layer under the tread and reduced tread gauge to keep down heat in the tire and a race compound and optimized footprint to increase the traction. Amongst the comprehensive testing that was done, a specific test was developed to assess the durability of the tire in terms of acceleration and speed for the Mean Green conditions. Tires were tested up to 350 km/h without structural defect.

1Standing kilometer – The truck starts off from a standstill, covering the 1,000-meter course in one direction and then the other. The average speed from the two runs is the official figure. Flying kilometer – The truck is moving before covering the defined 1,000-meter course in each direction.
