Everything I Thought I Knew About Tires Is Wrong


Especially painful is reading that my hard-earned intuition that high-TPI tires are more puncture-resistant than low-TPI tires is WRONG WRONG WRONG. I was convinced this was true, and had based that conviction on personal experience.

Of course, the assertion that TPI is inversely correlated with puncture resistance is, ceteris paribus, inversely correlated with puncture resistance, does not necessarily contradict the observation that high TPI tires are more puncture resistant, since ceteris are not paribus.
