‘Iron Knight’ sets new speed record with special tyres
GOODYEAR and Volvo have set a new speed record for trucks.
Riding on special racing tyres, the 4,5-ton “Iron Knight” Volvo truck achieved an average speed of 169,09 km/h in a time of 21,29 seconds over a kilometre from a standing start.
The 2 400 horsepower Iron Knight also beat the record for the 500-metre distance, at 131,29 km/h in 13,71 seconds from a standing start. If that is not impressive enough, during the record runs the Iron Knight reached a top speed of 276 km/h.
The technology for the unique truck tyres produced by Goodyear for the new world speed record truck is based on the experience gained in truck racing. The casings for the record truck tyres are standard latest generation Goodyear truck tyre carcasses, as used every day on European roads. The new world speed records achieved on the tyres demonstrate the technology leadership of Goodyear in the transport industry.
“With so much power and torque, ensuring that 4,5 tons of truck sticks to the track at speeds of up to nearly 280 km/h is a real challenge for the tyres,” said Laurent Colantonio, director Tyre Technology Commercial of Goodyear Europe, Middle East and Africa.
“The ability to develop tyres to break world speed records proves our prowess in using advanced technology and innovation to produce exceptional tyres. This is true for the Iron Knight’s tyres and also for our standard truck tyres that offer highest levels of performance to our customers and help them to reduce their total cost of ownership.”
The 315/70R22.5 Goodyear Iron steer tyres are based on Goodyear Truck Racing tyres, as used by all trucks in the Federation Internationale de l’Automobile (FIA) European Truck Racing Championship. The 495/45R22.5 drive tyres are capable of withstanding the incredible torque that the Iron Knight develops. Both tyres are built on standard Goodyear truck tyre carcasses with specially developed tread compounds and tread patterns. The world record tyres carry specific Goodyear “The Iron Knight” sidewall decorations.
The record run was carried out at a closed-off test track in northern SweKnight den. The Iron Knight was driven by Boije Ovebrink, who has more than 30 years’ experience of both car and truck racing and has previously broken five speed records. At the time of publication, the records are being reviewed by the FIA, the international motor sport association. — WR.
