Gwada kama da EPA/SAE: 25–35% karkara mai karkara a cikin tayar radial — wanda ke nuna saukin kai na kura

Tests da ke kama da EPA da SAE International sowa sun fada cewa radial tires suna da resistance gaba daya da 25 zuwa 35 percent ka karanci naka na old style bias-ply tires, don haka SAE J1269 standards. Rolling resistance yana amfani da roughly 30% daga ciki wanda ya daki big rig's fuel tank, saboda waɗannan cut down shine haɗuwa da real world gains. Truckers za su iya expected around 8 zuwa 12% ingancin fuel efficiency lokacin da suyi zuwa radial tires. Shirya abokin cin mutum alone take up over 30% daga ciki wanda fleets ya shirya a kowane watan, waɗannan kind of savings really add up a makon bayan rana ga company bottom lines.

Tread-to-shoulder geometry da saufin sidewall: Ka karce parasitic deformation loss

Radial tires suka samun efficiency ta hanyar precision engineering na key stress points. Tsaro da suke ba su:
