Frank brings up a good point.

The best information I have says that the failure rate of the Firestone tire was about ½%. Other tires on the same vehicle had much lower failure rates – as did other tires in other applications.

So if we are comparing failure rates of tires, remember that you have to have a fairly large sample size.

And the bursting pressure of tires? Most of the figures reported are for NEW tires. I have seen very old tires burst with as little as 35 psi in them. Obviously older tires are going to have lower bursting pressures, the question is where on the curve are your tires.

I urge caution when overinflating tires as the consequences of a tire burst can be quite severe.
