Okay, now I'm really confused. I read elsewhere that the artificial stuff did not meet the specifications for radials and that the industry returned to using natural rubber. This from the Ohio Dept. of Natural Resources: "The tire industry consumes 65 percent of all rubber compounds produced worldwide, but it is not a candidate for extensive re-use of recycled tire rubber with today's technology. Because of speed, safety and other performance requirements of tires, they need to be made mostly using virgin rubber compound. But mixing five to 15 percent recycled rubber into the virgin rubber provides a few advantages in the production process, including better mixing properties and an increase in plant efficiency due to reduced curing times. Some tire manufacturers routinely use crumb rubber as a filler, especially to make treads on passenger car tires, farm equipment tires and solid rubber tires." Somebody help me, please!
