That's a fair point, Trakhak, and in the world of manufactured goods made by high-volume makers, there is always a non-zero and finite amount of risk. (I'm wearing my engineer hat now.) Every company produces defects, and the rate of defects is not knowable. I used to deal in large volumes of computers so I had a bigger sample than most people, by far. I would hear anecdotes about this brand or that brand being either better or worse than the others, and I usually kept my mouth shut because some people don't understand the significance of sample size.

And even when I'm being scientific about it, I'll still have biases from my experiences. And that leads me to prefer certain companies over others, whether it's fair or not.

In 27" tires, we still have good choices but not nearly as many as with other sizes.
