That could explain why I'm not getting any traction. . .

My sucky G-Forces are over a year old. My light car with big tires heat
cycles them to death before the rubber scrapes off.

I'm glad I asked!

But if that's true, then how do the street tires maintain their
sticktion year after year, hundreds of heat cycles? Or do they also lose
it?
