Just think of the forces that a tire encounters, he said. In just one revolution you're going to slam its tread into the pavement, drag its face across the pavement, and then subject the entire body to tremendous g-forces--and that's without even going on track or generating major slip angles. Now picture that at 60 mph.
and yet the company he works for makes tires that are supposed to last 80,000 miles.... REALLY???? The sidewalls are typically crap by 10k-15k miles........
