The ford 450 on 550 ues them. They are as hard as a rock. They make them in E,F,G,H rang. They handle weight very well. Because of how hard they are there not good snow tires. We service the power company trucks, the 550 fords use these tires up fast. They are 4wd so they use drive tires all the way around, when on front they chop real bad and quick. The ups trucks that come here use steer tires on front and get good milage from them. Because of our state makeing drw such a hassle to owen if we change to srw we will go to 19. 5. We tow big loads.
