‘Iron Knight’ sets new speed record with spe­cial tyres

The Witness - Wheels - - TRANSPORT -

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.
